Luster-cancel, small beam spot sensor head

CZ-H37S

Four types of sensor heads selectable according to target conditions and size.The luster-cancel type cancels the influence of the luster of a target. The adjustable spot type allows adjustment of the beam spot size according to the target. The fluorescence detection type can detect fluorescent materials. These sensor heads offer highly stable detection while solving conventional problems.

Extremely high powerUtilizes the world’s first hybrid structureThe SUPER RGB sensor was developed by a dramatic redesign of the sensor head structure to improve overall performance. The transmitter uses an optical fiber, which creates an incredibly uniform beam spot and helps reduce the size of the sensor head. The light-receiving circuit is built into the sensor head, enhancing its detection ability and improving stability.

RGB light source for triple 16-bitcalculationThree-color light source for accurate target recognitionThe SUPER RGB sensor incorporates three separate color LED’s. The signal from each color is converted into 16-bit data in the receiver to enable color recognition. This ensures accurate detection regardless of target vibration.

First-in-its-classSimple sensitivity adjustmentOne-touch calibrationThe SUPER RGB sensor can be calibrated with the push of a button. This simple approach eliminates variation between operators and ensures continuous, stable detection.

What is “luster”?

Less affected by shape, position, inclination, and surface luster (Patent-pending)

The CZ-H35S/CZ-H37S incorporates a polarizing filter which cancels the reflection from the glossy section and only recognizes targets by their color components. The CZ-H35S/CZ-H37S maintains accurate detection despite changing target conditions.

As the picture on the right shows, depending on the illumination some sections on a pepper’s surface can appear white. Like human eyes, conventional sensors can not recognize the correct colors of such a target.

Long detecting range of 1.97" to 3.74" (50 to 95 mm)Detection is available within a range of 1.97" to 3.74" (50 to 95 mm). The sensor can be mounted at a long distance and is less affected by changes in target position.

Detecting the presence/absence of greaseBy canceling the influence of surface luster and target position, the CZ-V20 reliably detects grease, despite its non-uniform shape and position.

Detecting marks on bags printed with multiple colorsThe luster-cancel type stably detects marks on bags even when the background of the mark vibrates or has luster. The small beam spot ensures reliable detection of even small marks.

Differentiation between the front and back sides of chips after being sealed in embossed tapeThe luster-cancel type, which cancels the influence of specular reflection, stably differentiates between the front and back sides of chips even through a transparent film.

Checking parts assemblyThe enhanced detection ability ensures stable detection of dark-colored targets.

RGB light source for diversified target recognition

Accurate target recognition

Single-color light source

Almost no difference is recognized between certain colors, resulting in unstable detection.

The received light quantity is converted into a ratio of three colors, and the target is recognized by its color. This ensures accurate detection.

High resolution amplifier for triple 16-bit calculation

The SUPER RGB sensor enables stable detection by using a three-color light source.

Dual digital display & Direct access

When the target position changes, the received light quantity changes according to the distance between the target and the sensor head, resulting in unstable detection.

Both the current value and set value are displayed simultaneously. Sensitivity and fine adjustment can also be done manually.

Even when the target position changes and the received light quantity changes, the ratio of the three colors does not change. Stable detection is ensured.

In the Super I mode, the sensor detects the received light quantity and automatically selects the most stable light from seven patterns. (There is no need for complicated settings because the light source is automatically selected during the sensitivity setting.)** In reality, the color of the emitted light does not change because the light combination is selected by the receiver.

Automatic calibration adjustment After the sensitivity setting is complete, the set value can be finely adjusted by detecting actual acceptable or unacceptable targets and adding (increasing) or excluding (decreasing) the set value. (Patent pending)

External calibration functionThe sensitivity can be adjusted by using an external device such as a PLC.

Shift functionThis function is useful for detecting subtle color difference. When there is a change in the surrounding environment over time, the displayed value can be compensated with the external shift input. (Patent pending)

Attenuation functionWhen the reflection from a target is too strong, the attenuation function can be used to decrease the sensitivity.

Three types of timer functionsThree types of timers are available: ON-delay, OFF-delay, and One-shot. The timer value can be set between 1 ms and 1,000 ms.

When the difference in sensitivity between the target and the background is small, providing shift inputs periodically will compensate for data variations.

Note: The expansion unit of the FS-V20 Series cannot be connected to the main unit of the CZ-V20 Series. To connect the FS and CZ Series units, connect the expansion unit of the CZ-V20 Series to the main unit of the FS-V20 Series. To connect two or more expansion units, connect the CZ-V20 Series units on the right of the FS-V20 Series units.

Advanced features that provide 100% reliability

Four independent outputsThis function is useful for target differentiation. The sensor stores data of four types of targets simultaneously and allows the setting and output for each target independently. When the C or C+I mode is used, the bank function enables differentiation of up to eight different types of targets.

Applications

Detecting labels on white containersThe fluorescent component contained in a label is detected to check for the presence/absence of the label. Since the detection uses the fluorescent components, it can stably detect even white labels on white containers.

Detection of presence/absence of invisible printThe CZ-H52 detects the presence or absence of the print in invisible ink which contains a fluorescent component. The fluorescence detection UV sensor can stably detect print which cannot be detected with reflective type photoelectric sensors.

Detection of presence/absence of instruction sheets (package insert) The CZ-H52 detects the fluorescent component contained in paper to check whether the instruction sheet (package insert) is properly inserted into each medicine package.

Checking grease application on ball bearingsThe grease application is checked by detecting the presence/absence of the fluorescent component contained in it. Even glossy metal targets can be stably detected by ignoring the influence of specular reflection.

Detection/operation indicatorsThe detection and operation indicators show the current status of the detection.

UV ON indicator

Detection indicator

Detecting fluorescent marks without being affected by patterns or colors The CZ-H52 emits UV light from the transmitter and detects the reflected light which was converted into visible light by the fluorescent material. Fluorescent materials and paints are normally invisible, however, they reflect visible light when UV light is applied.

Targets which may contain fluorescent materials/paints ■ Fluorescent label ■ Fluorescent chalk ■ Fluorescent lubricant■ Fluorescent dye ■ Paper ■ Adhesive ■ Marking tool/ink-jet printer■ Fluorescent color ■ Label ■ Sticker ■ Optically bright materials■ Transparent film ■ Marking ink ■ Grease ■ Ink and varnish/lacquer■ Felt-tip pen ■ Printing ink And so onThe CZ-H52 may be effective for detecting the above targets.

Super-small head for space saving The small sensor head measures only 0.59" (W) x 1.30" (H) x 0.94" (D) (15 x 33 x 24 mm). It can be easily mounted in tight spaces.

Many targets contain fluorescent materials or paints. The fluorescence detection UV sensor may be able to detect targets which cannot be detected with photoelectric sensors. Try your target in an actual situation.
