Electrical Characteristics Operate TimeThe time that elapses between the instant power is applied to a relay coil and the moment the contacts have closed. In case the relay has several contacts, the duration of the operate time shall be considered to end when the last contact has closed unless otherwise specified. Release time is always specified at 20°C unless otherwise noted. Operate bounce time is not included in the operate time of a relay.
Release TimeFor an SPDT relay, the release time is the time that elapses between the instant a relay coil is de-energized, and closure of the NC contacts. For an SPST relay, the release time concludes at the opening of the NO contacts. Release time is specified at 20°C unless otherwise noted. Release bounce time is not included in the release time of a relay.
BounceIntermittent opening and closing of contacts caused by vibration or shock resulting from the collision of the relay's moving parts.
Operate Bounce TimeThe time interval between the initial closure of the NO contact and when the bounce ceases.
Release Bounce TimeThe time interval between the initial closure of the NC contact and when the bounce ceases.

all contact terminals2. Between contacts of a different polarity: Between contact
terminals of a different polarity3. Between contacts of the same polarity: Between contact
terminals of the same polarity
Dielectric StrengthThe ability of electrically isolated parts within the relay to withstand high voltage applied across them without arcing. Typically, an acceptable leakage current is established at a particular voltage for a specified duration.
Mechanical Characteristics Vibration ResistanceVibration resistance of a relay is characterized by two values:
Malfunction Durability, refers to the maximum vibration the relay can withstand without changing state (vibration doesn't cause closed contacts to open or open contacts to close).
Mechanical Durability, refers to the maximum vibration the relay can withstand without causing it to permanently change its operating characteristics.

Contour and Shape Contour DimensionRelay for automobile PCBFor miniature relays, dimensions (either nominal or maximum) are provided to aid the customer in the design process.
General purpose relayMaximum dimensions are shown as a reference for design.
MarkingVarious markings are used such as relay type, voltage rating, internal connection diagram, etc. Because of space restrictions on the surface of smaller relays, they may not display all of the information found on larger relays.
Mounting Orientation MarkThe top of all Omron relays are marked to indicate the location of the relay coil. Knowing the terminal location aids in designing PCB patterns, and when spacing components. Also, the printing makes it easy to discern pin orientation when automatic or hand-mounting the relay.
Note: In a contour dimensional drawing, PCB process dimensional drawing or terminal layout/internal connection diagram, the directional mark is found on the left. JIS contact symbol is not inscribed to match with case marking.

Notice to ensure safety• This relay is intended for automotive use only. Do not subject it
to any other use. Refer to the specification and confirm that the relay meets the application before using any relay from this catalog.
• Confirm acceptability for safety critical applications by appropriate testing or contact Omron.
• Do not use the relay for loads which exceed the rated values given in the data sheet. Failure to do so may result in unforeseen consequences such as insulation failure, smoking, breakdown of operation, etc.
• Do not apply over-voltage to the relay coil. Do not apply AC power to a DC relay coil. Be careful not to exceed the temperature ratings of the relay.
• Do not make incorrect connections to the relay terminals.
• Endurance (Lifetime) is significantly affected by changes to the load and switching condition. When using the relay, check the relay behavior with an actual product under actual conditions. Use the relay within timing characteristics it can meet according to the data sheet.
• Carry out the proper number of confirmation tests with an actual product for each application or contact Omron.
• A relay is a precision part. Do not apply vibration and shock beyond the specified value. Do not drop the relay. Do not use a relay that has been dropped.
• Do not remove the case of a relay or modify the terminals in any way.
• Do not touch the relay terminal or opposing mating terminal while applying current. Electric shock may occur.
• Do not use a relay under any environment that contains flammable or explosive gas. Fire or an explosion may result.
When using a relay• As with all technologies, relays may not always behave as
expected. Therefore, evaluation under actual application conditions is always best.
• Each performance rating in this catalog is based on the value under controlled conditions (i.e. temperature, humidity, etc 86~106kPa) unless otherwise specified. Confirm not only load condition but also actual environmental conditions for actual use.
• Reference data in the catalog is based on measurement values from sampling of production. The values are as accurate as possible and believed to be correct at the time of publication. Due to production necessity or other reasons, specifications may change without notice.
• Each rating or performance value indicated on the data sheet is collected under specific controlled conditions. Changes to or introduction of more complex conditions may cause changes to ratings or performance values.
• When a relay is used outside the recommended conditions, there is no way for Omron to predict the failure mode or results of the failure. Omron will remain blameless for the results of applying relays outside of the recommended parameters described in this catalog.

Notice related to relays
➊Coil Input(1) Maximum Applicable VoltageThe maximum voltage applicable to a relay is determined in accordance with the coil temperature rise and the coil insulation material’s thermal stability. If the thermal limit of the wire insulation is exceeded, the coil may become damaged by burning or a coil layer short may occur. Do not exceed the values given in the catalog; failure to do so may cause unfavorable results.
(2) Applied Voltage to the CoilThe voltage applied to the coil should not exceed the rated voltage. Applying a voltage that exceeds the rating decreases the switching time, but can also contribute to a deterioration in durability performance due to an increased incidence of contact bounce, and a shorter relay life due to an increased operating temperature.
(3) Ripple Ratio of Coil CurrentThe power source for DC-operated relays is in principle, a power source with a maximum ripple of 5%. If the ripple of the voltage applied to the coil is too great, undesirable performance characteristics may emerge. For instance, in a half-wave rectifier circuit with a smoothing capacitor, the ripple increases as the value of the smoothing capacitor decreases.
(4) Waveform of Applied Voltage to the CoilA coil voltage signal that gradually increases or decreases is not desired. A rectangular (square) waveform is preferred. It cannot be assumed that the relay will operate or release at the moment the coil voltage reaches the limits shown on the specification sheet. Voltage applied to the coil should increase or decrease sharply. Otherwise contact operation time may be prolonged or other malfunction may occur. With longer operating and release times, contact endurance may decrease. Also, contact welding may occur.
(5) Lack of Applied VoltageWhen the applied voltage to the coil is low, the relay may not operate or its behavior may become unstable. Contact endurance may decrease, or contact welding may occur (among other possible drawbacks.) Also, relay malfunction can occur below the specified vibration and shock values. Hence, the rated coil voltage should be applied to the relay coil.
(6) Coil PolarityIt is necessary to apply the correct polarity to the coil in instances where the coil has a diode or other polarity sensitive device employed as a surge suppressor. Applying reverse polarity will damage the suppression device and possibly cause damage to the circuit in which the relay is installed.When using a polarized (latching or moving loop) relay, a permanent magnet is employed. In such instances, the relay will not operate if the coil voltage or pulse is applied in the opposite polarity.
(7) Changes in Operating Voltage due to Coil Temperature Rise
The specified operating voltage value in the catalog may not be satisfied under hot start conditions and/or an ambient temperature greater than 20°C. It is necessary to confirm operation under the actual conditions in which the relay will be used. Coil resistance and operating voltage will increase linearly as the coil temperature rises. The temperature coefficient of resistance for copper wire is about 0.4% per 1°C, and the coil resistance increases at the same ratio. Values for operating and release voltage in the catalog are given at 20°C.

Notice related to relays
(8) Load Switching FrequencyThe acceptable maximum switching frequency will vary with the type of load, voltage, current, etc. The user must confirm operation under actual application conditions. When the switching frequency is beyond the relay’s capabilities, it may be impossible for the relay to interrupt the circuit properly.
(9) Infrequent Switching and Dry SwitchingIf a relay is used under a condition where it is subjected to very infrequent switching, the contacts may naturally form non-conductive surface films. These films may produce an unstable or unreliable contact resistance. This condition is also observed when "dry" circuits are switched (meaning little or no contact current.) The development of these films is highly dependant on environment and load type. It is imperative that these conditions be considered and evaluated. Circuitry can be employed to lessen or eliminate the appearance of this phenomenon.
(10) Continuous Energization for Extended PeriodsIt is not recommended to use a relay in a circuit where the coil is energized for long periods (such as months or years.) These conditions are severe on the coil and contacts.
(11) Surge ProtectionThe reverse voltage that is generated by the coil when it is switched off can cause damage to a semiconductor used to drive the coil and may result in circuit malfunction. Some countermeasures are to attach a surge suppressor to both ends of the coil or to select a model with a built-in surge suppressor. As surge suppression will cause the release time to increase, operation in the actual circuit should be confirmed.When using a diode for surge suppression, it is good to use a device that has tolerance for external surges. Repeated peak inverse voltage rating and forward bias current rating should be considered.Surge voltages shall not be applied to the relay coil. An instance where this may occur would be one in which an inductor is in parallel with the relay's coil. The surge generated by the inductor may damage the relay coil's surge protection device (resistor or diode) if so equipped.
(12) Leakage Current to the CoilLeakage current should not be allowed to pass through the relay's coil. See Improvement example 1 and 2.
Example of a circuit in which leakage current occurs:
Improvement example 1:
Improvement example 2: The case output value, which is the same phase as input, is necessary.
(13) Sequence CircuitWhen configuring a sequence circuit, care must be taken to ensure that the circuit does not malfunction due to sneak current. When designing a sequence circuit, it is important that, of the two power lines, the top being considered positive and the bottom negative (this applies to AC as well as DC circuits), that the contact circuits (relay contacts, etc.) be connected to the positive line, while the load circuit (relay coil, timer coil, magnet coil, solenoid coil, etc.) be connected to the negative line.
An example of a sneak circuit is shown below. After contact A, B and C have been closed, in turn energizing X1, X2 and X3, if contacts B and C are opened, a series circuit consisting of A, X1, X2 and X3 is formed which can cause the relays to not release or to generate heat. In a DC circuit, the sneak current can be prevented with the use of diodes.
An example of a correct circuit is shown below. In a DC circuit, the sneak current can be effectively prevented by using diodes.

➋Contact Output (Load Circuit)(1) Maximum Switching PowerTo select a relay, refer to catalog curves and data to determine the maximum switching power and contact endurance. Confirmation of maximum conditions under actual circuit conditions is still necessary. Use the following graph to evaluate maximum switching power.For example, the maximum contact current I1 can be determined when contact voltage V1 is known. Switching times can be estimated by using the data in the curve for I1.
For example, Contact switching current is 2A---*1 if Contact voltage = 40 V.Switching durability at a maximum contact current 2A is about 300000 cycles.---*2
Maximum Switching Power
Endurance Curve
(2) Switching Voltage (Contact Voltage)When switching DC loads, the acceptable switching power will decrease as voltage increases. This concept is demonstrated in the “Maximum Switching Power” graph above. At the lowest voltage, the maximum switching power is 90 W. However, at the highest voltage shown, the maximum switching power is 50 W.
Applying voltage or current that exceeds the maximum will result in the following:1. The carbon generated by load switching will accumulate
around the contacts and cause a degradation of dielectric performance.
2. The contact material transfer and consumption will cause deposits, which can cause contact locking and lead to contact malfunction.
(3) Switching CurrentThe current applied to contacts during switching will have a significant effect on the contacts' performance. Motors and lamps produce large inrush currents. As inrush current increases, the amount of contact material consumption and transfer will increase. Deposits, pip and crater, or other conditions, lead to mechanical locking and other contact malfunctions. (See below for typical examples of the relationship between load and inrush current.) If a current greater than the rated current is applied from a DC source, it is possible to have a situation where the opening contacts can not extinguish the arc. A continuous uninterruptible arc may occur.
DC Loads and Inrush Current
(4) Switching EnduranceSwitching endurance depends on many factors such as; the drive circuit for the coil, load type, switching frequency, switching phase, and ambient conditions. Evaluation under actual conditions is necessary. The switching endurance in the catalog is based on the following information.
(5) Resistive Loads and Inductive LoadsThe maximum acceptable switching power for an inductive load is lower than that of a resistive load of equal current draw due to the influence of the electromagnetic energy stored in the inductive load.
(6) Signal Level Loads or Dry SwitchingThe appropriate relay should be selected based on load type, contact materials, and contact system (small signal load, dry switching, etc.) Failure to do so may affect relay reliability.
(7) Contact Switching PhenomenonWhen switching a DC load, one contact typically gives up material from vaporization caused by arcing. The vaporized metal is sometimes deposited on the opposite contact. The end result of this occurrence is the mating of a convex, with a concave, contact. To minimize this effect, an arc reducing contact protection circuit such as a diode, is appropriate. Careful selection of contact materials and evaluation under actual operating conditions are also important.

Notice related to relays
(8) Contact Protection Circuit (Arc Reduction)It is recommended to employ a contact protection circuit to increase the service life of the relay, to suppress noise, and to prevent the generation of carbine and nitric acid which otherwise will be generated at the contacts during switching. Examples of surge suppressors are shown in the table below.
1. The effect of the protection cannot be assumed due to variation in the load or relay characteristics. Verify proper operation under actual load.
2. When using a surge suppressor, the release time may be prolonged. Operation under actual load should be verified.
Examples of surge suppressors
Avoid use of a surge suppressor in the instances shown below.
(9) Surge Protection from the External CircuitThe protection circuit, such as a surge suppressor, should be attached in the area where the surge exceeds the withstand voltage value of the relay. Insulation breakdown and short circuit may occur between the coil and contact, where the voltage exceeding the maximum withstand voltage is applied, or between contacts of opposite polarity.
(10) Motor Switching for Forward and Reverse OperationIn the case of switching a motor for forward and reverse operation, two relays or a dual relay should be used (See the figure below.) The lag-time (OFF time) in the operation sequence of the relays should be 100ms minimum.
ItemCircuit example
ApplicabilityFeatures and remarks Element selection
Type DC
CR type
OKLoad impedance must be much smaller than the CR impedance. Current flows to the inductive load though CR when the contact is open.
Optimum C and R values are:C: 0.5 to 1 uF for 1A switching current.R: 0.5 to 1 Ω for 1V switching voltage. These values do not always match with the optimum values due to the nature of the load and the dispersion in the relay characteristics. Confirm the optimum values through experiment. Capacitor C suppresses the discharge when the contacts are opened, while resistor R limits the current applied when the contacts are closed the next time. Generally, use C whose dielectric strength is 200 to 300 V. If the circuit is used with AC power source, use an AC capacitor (without polarity).
OKRelease time of the contacts will be delayed in case the load is inductive (relay, solenoid, etc.)
Diode type OK
The energy stored in a coil (inductive load) is routed through the coil as current by the diode connected in parallel with the coil, and is dissipated as Joule heat by the resistance of the inductive load. This type of circuit delays the release time more than the CR type.
Use a diode having a reverse breakdown voltage of more than 10 times the circuit voltage, and a forward current rating greater than the load current. A diode having a reverse breakdown voltage two or three times that of the supply voltage can be used in an electronic circuit where the circuit voltage is not particularly high.
Diode+Zener diode type
OK
This circuit is effective in an application where the diode type protection circuit alone is not sufficient because the release time is delayed too much.
The breakdown voltage to the zener diode should be about the same as the supply voltage.
Varistor type OK
This circuit prevents a high voltage from being applied across the contacts by using the constant-voltage characteristic of a varistor. This circuit also somewhat delays the release time. This circuit is effective if connected across the load when the supply voltage is 24 to 48 V. If the supply voltage is 100 to 200 V, connect the circuit across the contacts.
The cutoff voltage Vc must satisfy the following conditions (on AC, it should be multiplied by 2). Vc>(Supply voltage × 1.5) But, cutoff for high voltage does not work if Vc is set too high.

This circuit arrangement is very effective for diminishing arcing at the contacts when breaking the circuit. However, since electrical energy is stored in C (capacitor) when the contacts are open, short-circuit current of C flows into the contacts when they are closed. Therefore, metal deposition is likely to occur between mating contacts.
This circuit arrangement is very useful for diminishing sparking (arcing) at the contacts when breaking the circuit. However, metal deposition is likely to occur between the mating contacts.
Note: Although it is considered that switching a DC inductive load is more difficult than a resistive load, an appropriate contact protection circuit can come close to achieving parity of performance.

Notice related to relays
(11) Load Connection of a Multi-polar RelayIn a multi-polar relay, loads should not be connected in a way that could potentially create a different circuit (See the figure below.) This could cause a short between contacts due to arcing, and can break the relay or peripheral devices.
(12) 2-Point Power Shut-off using a Multi-polar RelayWhen designing a 2-point power shut-off circuit using a multi-polar relay, the relay should be selected based on the relay's structure, the creepage distance, and the spatial distance between poles (also considering whether or not there is an arc barrier.)Even when using a load within rating, operation of the relay under actual conditions should be verified. It is possible that a short will occur between unlike poles due to arcing at power shut-off causing peripheral devices to burn or break.
(13) Different Capacity Load ConnectionOne relay should not be used to switch both a large and small load. Switching a large load can impair the cleaning performance of a contact when switching a small load and result in contact failure.
(14) Power Supply SwitchingWhen switching a number of different power supplies, or switching power supply polarity, use more than one relay with sufficient lag time to prevent short circuiting the power supply.
(15) Circuits in which Contact a Contact Short OccursUsing a relay with a small clearance between the A and B contacts, or switching a large current with a relay that has both A and B contacts, can facilitate arcing between the contacts. Circuits should be designed so that if a relay's contacts become shorted, the circuit will not burn out or experience an over-current condition.
➌Mounting Design(1) Lead Wire Diameter for WiringThe lead wire diameter is decided depending on the value of the load current. The chosen lead wire shall be at least the cross-sectional area shown in the following table. If the lead wire is thinner than required, burnout will occur due to abnormal heating of the wire.
(2) Socket MountingWhen using a socket mounted relay, the lower rating of the two should be used. If the higher rating is used, abnormal heating will lead to burnout at the connected point.
(3) Installation DirectionRelays shall be mounted in the direction detailed in this catalog. Mounting direction may differ depending on relay type.
(4) Relays mounted close to a CPUWhen a relay is mounted near a noise-sensitive device such as a CPU, consideration of noise interaction must be taken during trace and circuit design. A relay switching large currents will create noise due to arcing, possibly leading to CPU malfunction.

➍Storage and Usage Environment(1) Using, Transporting and Storing the Relay When using, storing and transporting relays, avoid direct sunlight and keep normal temperature, humidity and pressure.• Oxides or sulfurized films may accumulate on the contact
surface if the relay is exposed to high temperature and humidity for long periods of time. That could be a root cause of failure like contact defect.
• Condensation may occur inside the relay if the ambient temperature changes sharply from a high temperature and humidity to a lower temperature. Condensation should be avoided because it may cause insulation failure.Furthermore, bluish-green compounds may be generated inside of the relay due to relatively strong arc discharge associated with contact switching at high humidity. Best overall relay performance is attained at low humidity.
• When relays have been stored for a long period of time, it is possible for various oxides to form on the terminals and contacts. Therefore, if such a situation were to occur, it is necessary to evaluate the readiness of relays for use.
(2) Ambient Environment• Do not use the relay in any area containing flammable or
explosive gas. Fire or explosion may occur due to arcing or heating that is generated when switching the relay.
• Non-sealed relays should not be used in an excessively dusty environment. Loose contact may occur if dust enters the relay. It is recommended to use plastic sealed relays or metal hermetically sealed relays when a dusty application environment is foreseen.
(3) Gases (Silicone gas, sulfuric gas, organic gas)Relays should not be used or stored near silicone, sulfuric (SO2, H2S) or organic gases. Degradation of the contacts may occur or solderability of the terminals may be adversely affected. Storage or use in an environment containing silicone gas may cause loose contacts to occur. The following table shows some countermeasures.
(4) Dust When an unsealed relay is used or stored in an excessively dusty environment, contamination may enter the relay and obstruct the contacts or other moving parts. The result may be failure to physically or electrically close the contacts. Loose contacts or short circuit may occur if conductive substances enter the relay. In those cases, a fully sealed relay is recommended.
(5) Exportation to a Tropical RegionWhen a relay will be used or stored in a tropical region, the following types are recommended:• A Relay that is designed and manufactured specifically for
tropical conditions.• A Plastic sealed relay• A Hermetically sealed relay
Failure to consider application in tropical regions may lead to unexpected corrosion of metal parts.
(6) Invasion of Water, Chemicals, Solvents, & OilDo not use or store the relay a place where it may be exposed to water, chemicals, solvents or oil. Rust, corrosion, resin deterioration or other adverse conditions may occur. Also, with solvents such as thinner or gasoline, parts may deteriorate and markings may disappear. With exposure to oils, a clear (polycarbonate) case may become clouded or cracked.
(7) Vibration and ShockVibration and shock over the rated value should be avoided. Excessive shock or vibration may cause relay part deformation or damage and lead to relay failure. To minimize vibration and its effects, it is recommended to mount the relay in a location isolated from sources of vibration.
(8) External Magnetic FieldMalfunction may occur if using the relay in the presence of a strong magnetic field. Do not use the relay in any location where external magnetic field of 800A/m or more exists. Arc discharge generated between contacts during switching is distorted in the presence of a magnetic field. A short circuit or insulation failure may occur.
(9) External Physical LoadsDo not use or store the relay in a state where a physical load or stress is applied to the relay from an external source. It could be a root cause that the relay causes malfunction or cannot keep the initial characteristics.
(10) Adhesion of Magnetic ParticlesDo not use the relay in the presence of magnetic particles. Performance of the relay may not be maintained if particles attach themselves to the case.

➎Relay Mounting(1) Common Subdivision➀Do not solder a tab terminalDo not solder a lead wire to a tab terminal. Contact failure can occur due to relay deformation and flux immersion.
➁Do not cut a terminalPerformance will be impaired.
➂Terminal deformationDeformed terminals should not be used, even after repair. Unacceptable force may be applied to the relay and initial performance may not be kept.
➃Relay replacement and wiringWhen replacing a relay or wiring, ensure safety by turning the power OFF at the coil and load before beginning work.
➄Coating and packingFlux, coating agent or packing resin shall not penetrate into a relay. Contact failure or operation defect can occur. When coating or packing, a plastic sealed relay shall be used. Coating agents and packing resin shall not contain silicone. When coating, relay operation in the actual unit shall be checked.
Coating agent type
(2) PCB RelayUltrasonic cleaning of relays shall not be performed. Contact sticking or coil disconnection may occur due to the resonance of internal components.
(3) Plug-in Relay➀Front connection socket• Screw to attach a socket
A front connection socket shall be attached firmly using screws after making attaching holes. If the socket is not securely fastened, a socket, lead wire, or relay may come off due to vibration or impact. A socket mounted to a 35mm DIN rail is also acceptable.
• Screwing a lead wireA lead wire shall be tightened to the following torques.①M3 screw socket: 0.78 to 1.18 N·m②M3.5 screw socket: 0.78 to 1.18 N·m③M4 screw socket: 0.98 to 1.37 N·mWhen using a front connection socket, a lead wire will come off and abnormal heating may occur if the screw is under-torqued. If the screw is over-torqued, the screw head may become stripped.
• A Holding clasp shall be used to maintain the reliable connection between the relay and a socket.The relay may come off from a socket when abnormal vibration or impact is applied.
➁Relay insertion/removal directionThe insertion and removal of a relay shall be performed normal to the socket surface.
If the relay is inserted or removed at an angle, contact failure and relay terminal bending may occur.

➏Relay for Automobile PCB(1) PCB Selection➀PCB MaterialsGenerally, the substrate of a PCB is made of glass epoxy, paper epoxy, or paper phenol. The table below shows various properties of typical types. PCB and relay selection should be made in light of the intended use. Of these, the glass-epoxy or paper-epoxy PCB is recommended for mounting relays.
➁PCB ThicknessPCBs having a thickness of 0.8, 1.2, 1.6 or 2.0mm are generally used. A PCB that is 1.6mm thick is best for mounting relays. This determination is based on relay weight and terminal length.If a PCB of insufficient thickness is used and displays warpage, relay performance may suffer. Care should be taken to consider board size, part weight, mounting methods and usage environment to avoid these complications.
(2) Mounting Interval➀Ambient TemperatureFor the mounting interval, follow the recommendations described in the catalog.When many relays are mounted together, they may generate abnormally high heat due to the thermal interaction between the relays. Therefore, provide an adequate distance between the relays to dissipate the heat. When using a relay, be sure to check the minimum mounting interval.Also, if multiple PCBs with relays are mounted within close proximity to each other, the temperature may rise. In this case, preventive measures must be taken so that the ambient temperature falls within the rated value.
➁Mutual Magnetic InterferenceRelay characteristics may change due to the magnetic field generated by other relays. If two or more relays will be mounted in close proximity to each other, use the relay only after checking for acceptable operation.
(3) Pattern Layout to Protect from Noise (EMI)➀Noise from the CoilWhen the relay coil is switched off, reverse electromotive force is generated by the collapsing of the coil's magnetic field. When this occurs EMI noise appears. A diode across the coil can help absorb the surge. The figure below is an example of a circuit used to reduce noise.
➁Noise from the ContactNoise may be introduced into the electronic circuit when switching loads that generate arcing on contact points. Examples would be any inductive load such as a motor, solenoid, or magnetic clutch. Consider the following points when determining the routing of conductors on the PCB:1. Keep the current carrying path as far away from signal paths
as possible.2. Design the shortest possible current-carrying path.3. Shield from the electronic circuit by employing a ground plane.
(4) Shape & Position of Solder PadsThe solder pad should be on the center line of the copper-foil pattern, so that the soldered fillets become uniform.
A break in the circular land area will prevent molten solder from filling holes reserved for components which must be soldered manually after the automatic soldering of the PCB is complete.
(5) Stabilization Method for PCBAlthough the PCB itself is not usually a source of vibration or shock, it may amplify or prolong the vibration by resonating with external vibrations or shocks. Securely fix the PCB, paying close attention to the following points.

(6) Automatic Mounting of Relays on PCBs➀Though-hole MountingThe following tables list the processes required for mounting a relay onto a PCB along with recommendations at each point in the process:
Process 1 ① Do not bend any terminal of the relay for the purpose of holding it on a PCB. Doing so may cause the relay to malfunction.
② Be sure to process the board in accordance with the process drawing.
Possibility of automatic placement
Placement
Process 2 ① To apply flux to a flux protected or fully sealed relay, a sponge soaked with flux can be used. Place the relay in the holes drilled in the board and press the board (with relay still mounted) firmly against the sponge. The flux will be pushed up the relay's contact legs, and through the board holes. This method must never be applied with unsealed relays because the flux will penetrate the relay. Be careful not to use too much pressure to avoid flux intrusion into flux protected relays (not fully sealed.)
② The flux used with the sponge must be a non-corrosive resin type flux. For the flux solvent, use an alcohol-based solvent, which tends to be less chemically reactive. Apply the flux sparingly and evenly to prevent penetration into the relay. When dipping the relay terminals into liquid flux, be sure to adjust the flux level, so that the upper surface of the board is not flooded with flux.
③ Flux must not be on any other area except the relay terminals. Insulation deterioration might occur if flux is applied on the bottom of the relay, etc.
Flux application
Process 3 Preheat the board to a temperature of 100°C maximum within a period of approximately one minute for smooth soldering. The characteristics of the relay may change if it is heated to a high temperature for a long time.
Possibility of preheating

Process 4 Automatic soldering Manual soldering
① Wave soldering is recommended to assure a uniform solder joint.
• Solder: JIS Z3282, H63A• Soldering temperature: About 250°C (About 260°C in case of
DWS)• Soldering time: within 5sec (In case of DWS, about 2sec for
first time and about 3 sec for second time.)• Adjust the level of the molten solder so that the board is not
flooded with solder.
① Solder with the following conditions flattening a soldering iron tip.
• Solder: JIS Z 3282, H60A, or H63A (containing resin-type flux)
• Soldering iron: rated at 30 to 60 W• Tip temperature: 280 to 300°C• Soldering time: within 3 sec② The solder in the illustration shown above is provided with a
