Contact ArrangementRelays manufactured by Crydom have one of the following contactarrangements:

Form A : Normally open - energise to close contactsForm B : Normally closed - energise to open contactsLatching : Contact is bistable - energise ÒsetÓ coil to close

contacts; energise ÒresetÓ coil to open contacts

Coil SuppressionIt is recommended that all relay coils be suppressed by a diode. Thisis essential for latching relays. Operate and release times for therelays are quoted with coil suppression fitted.

Soldering & CleaningCrydomÕs reed relays are high performance products and thematerials and methods of construction are significant factorsin achieving performance specifications. The following guidelinesshould therefore be followed when adopting assembly, soldering andcleaning processes:

1) Soldering. Crydom propose that either low residue fluxes areused in the soldering process (to eliminate the need for cleaning),or that the reed relays are fitted onto the PCB after the cleaningprocess has taken place. If a solder bath is employed themaximum immersion time recommended is 10 seconds at 250¡Cor 3 seconds at 350¡C.

FRD12000/13000 Series: Electrical connection to the contacts ofthe FRD12000/13000 Series relay is via the reedswitch leadout.Care must be taken when hand soldering, as physical andthermal shocks can damage the glass to metal seals. A thermalshunt (aluminium clamp) carefully applied to the reedswitchleadout, adjacent to the glass seal will reduce the chances ofbreakage due to thermal shocks.

Alternatively, the relays should be warmed prior to soldering.

2) Cleaning. It is impossible for Crydom to offer blanket approval ofmethods, due to the many and varied automatic cleaning systemsnow available to conform to recent legislation.

If, after the soldering process, the customer wishes to clean PCBÕscontaining Crydom reed relays then the use of post operativecleaners such as IPA or HCFC based solvents with low pressurebrush applicators is recommended. Any customer wishing to usean alternative cleaning system should ensure that the fluids andprocesses are appropriate for application on Crydom reed relays.CrydomÕs devices are not hermetically sealed and as such,exposure to certain fluids can result in the degradation of therelay materials and subsequently a reduction in the electricalperformance. Please contact Crydom for further information onthe suitability of various cleaning solutions.

High Voltage Reed Relays

The principal function of a high voltage reed relay is to isolate as higha voltage as possible. In order to achieve this all Crydom high voltagereed relays employ evacuated reed switches. These switches areavailable with either Tungsten or Rhodium contacts depending uponthe switching characteristics required. As with all reed relays theyare susceptible to mutual magnetic interference when mountedin close proximity to each other. These parameters are discussed ingreater detail below.

Isolation VoltageThe isolation voltages specified correspond to DC or AC peak. Atmains frequencies (e.g. 50 or 60Hz) the two may be considereddirectly equivalent.

Contact Material - Rhodium vs TungstenRhodium contacts should be used where very low contact resistanceis required or when power switching at <1000V is undertaken.Tungsten contacts perform best when switching high voltages (1-10kV) at very low current. It should be noted that switchingpower will reduce relay operating life - the factory should becontacted for advice on specific applications.

Magnetic ScreeningCrydom high voltage reed relays are generally supplied withmagnetic screening fitted. However, this is not absolute and so, if theminimising of interference is critical, the mounting configuration infigure 1 below is recommended.

application notes

Figure 1 : Recommended Mounting for ‘S’ and ‘D’ Series High Voltage Reed Relays

RF Reed Relays

The basic requirements of RF reed relays are to provide minimal RFsignal loss and very low contact resistance over a long operatinglifetime. This is achieved in Crydom RF reed relays through the use ofcopper plated reed switches with Rhodium contacts in conjunctionwith carefully designed coil assemblies. They are intended for useacross the frequency range 1-30MHz and typical RF parameters foran RF reed relay across this band (measured in a 50 Ohm system) areshown in figure 2 below:

Particular to RF reed relays are the effects of RF and magneticscreening and these are discussed in more detail below. Also, highvoltage isolation considerations are specific to RF conditions.

RF ScreeningWhen an RF current is passed through the switch of a reed relay anelectromagnetic coupling between reed switch and coil results in someenergy being dissipated in the coil. This dissipation manifests itself asan addition to the effective series resistance (ESR) of the relay and, atcurrents of several amps, heating of the relay coil. RF coil heating isgreatest at high frequencies and varies in proportion to the square ofthe RF current carried in the switch. It is this factor which limitsmaximum carry current at high frequencies and ambient temperatures.The purpose of RF screening is to reduce these losses and extendrelay performance at high frequencies and high ambient temperatures.

Crydom RF reed relays are available with no screening, partialscreening and full RF screening of the coil, depending upon therequirements of the application.

Relays without an RF screen have restricted current carryingcapability at high ambient temperatures and frequencies (and ahigher associated ESR). However, this suits many typical ATUapplications well, as the highest currents occur only at the lowerfrequency bands (e.g. 2MHz).

Relays with partial RF screening have extended current carryingperformance at elevated ambient temperatures over unscreenedvariants.

Relays with full RF screening represent the ultimate in low loss RF reedrelay design. The ESR and resulting coil heating are significantly lowerthan for other types and this makes them suitable for applicationsin high ÒQÓ circuits where high currents are present over the wholefrequency range.

As an illustration of the effect of relay screening on ESR,measurements taken under load at 30MHz (i.e. the worst casefrequency) are shown in figure 3 below for fully, partially andunscreened ÒFRDÓ series reed relays.

Magnetic ScreeningWhen power is supplied to the coil of a reed relay a magnetic field isproduced. When relays are mounted in close proximity this can resultin mutual magnetic interference. However, Crydom RF reed relaysare generally not fitted with magnetic screens, as the presenceof ferromagnetic material around the coil can adversely affect ESRand RF coil heating as described above. For applications whererelays are mounted in close proximity the recommended mountingconfiguration is shown in figure 4 below.

Isolation VoltageAll withstand voltages are specified and tested at DC. However, highvoltage breakdown mechanisms at high frequency differ to those atDC. In general, breakdown across the reed contacts occurs at ahigher RF peak voltage than DC. Conversely, breakdown outside theswitch (e.g. switch to coil or screen), caused by surface tracking, canoccur more readily at high frequency than at DC. Verification of anyparticular voltage and frequency combination can be undertaken byCrydom upon request.

6 SeriesMiniature, Fully Screened, Open Frame. 3.5kV, 4A

Developed closely with RF design Engineers in the radio communications industry,

this new fully screened reed relay series, offers low RF loss and high current

carrying capability. The robust shell construction enables the customer to specify

contact pin configuration. The relay coil section is totally enclosed in a copper

screen, resulting in lower self-heating and RF loss. Together with Crydom's vacuum

reed switches, benefits include higher carry currents for a given frequency and

ambient temperature. Peak RF isolation voltages up to 3.5kV are achieved by

clever coil design maximising pin spacing. Switch connections are offered for

either PCB or Flying Lead mounting
