Feature

Dual Detection Modes: The photoelectric LED color sensor supports both color mode and mark mode. In color mode, it uses RGB tri-color LEDs to identify colors based on the reflected RGB ratio. In mark mode, it automatically selects the optimal single-color LED for high-speed mark detection.
Long Detection Range: Thanks to advanced optical and circuit design, the photoelectric LED color sensor achieves a reliable detection distance of 18–28 mm.
Anti-Jitter Performance: Equipped with adjustable hysteresis, the color identification sensor minimizes the impact of object vibration, ensuring stable operation.
Rectangular Light Spot: The color recognition sensor projects a rectangular light spot (approximately 1.5 mm × 7 mm at 23 mm), enabling precise detection on small or narrow targets.

3 Tips for Photoelectric LED Color Sensor Operation

Before teaching the photoelectric LED color sensor, confirm whether it is set to color mode or mark mode. The "COLOR" indicator light will be steadily lit in color mode and off in mark mode.
To teach the color sensor, first position it over the target color and press the ON button until the GOOD indicator flashes. Then, position it over the background color and press the OFF button to complete the setup.
Adjust the hysteresis setting to reduce the effects of object vibration. Press and hold the ON button for about 5 seconds until the hysteresis indicator flashes, then use the OFF button to select the desired hysteresis level (small, medium, or large).
