| High Light | Photoelectric safety device for automated doors ，IP67 blanking light curtain ，Safety device with blanking mode | ||
The JUTAI CL20-8L Photoelectric Safety Device is a professional protective sensing solution engineered exclusively for automated doors. It forms an invisible 8-beam light grid between the emitter and receiver, instantly triggering safety responses (door reversal, stopping, or alarm) when personnel, objects, or equipment intrude the detection area. With a dedicated Blanking Mode to avoid false alarms, IP67 rugged protection, and user-friendly design, it effectively prevents pinching, crushing, or collision accidents in industrial, commercial, and logistics environments—becoming an indispensable safety component for automated door systems.

| Component | Wire Color | Function | Detailed Notes |
|---|---|---|---|
| Transmitter | Red | DC12-24V Positive Power Supply | Must connect to stable DC power supply (12-24V); avoid overvoltage/undervoltage |
| Transmitter | Black | Ground (GND) | Connect to power supply negative terminal; ensure reliable grounding |
| Transmitter | Green | Reserve | No connection needed in basic use |
| Transmitter | Yellow | Reserve | No connection needed in basic use |
| Transmitter | White | Reserve | No connection needed in basic use |
| Receiver | Red | DC12-24V Positive Power Supply | Same power source as transmitter |
| Receiver | Black | Ground (GND) | Shared ground with transmitter |
| Receiver | Green | NO/NC Output (Default NO) | Connect to automated door control system's safety signal input |
| Receiver | Yellow | Configurable NC | Switches to NC output after Blanking Mode activation |
| Receiver | White | COM (Common Terminal) | Must connect to door control system's corresponding terminal |
| Fault Symptoms | Possible Causes | Detailed Solutions |
|---|---|---|
| Receiver's blue light flashes continuously | Emitter and receiver misalignment | Check parallel installation and adjust positions until blue light stabilizes |
| Transmitter's red light flashes fast | Power supply voltage too low (<9V) or too high (>28V) | Test voltage with multimeter and replace with stable DC12-24V adapter |
| Device works but door has no anti-pinch action | Wiring error or door control system issue | Recheck wiring and verify door control system recognizes safety signals |
| Unable to enter Blanking Mode | Operation timeout or environmental factors | Restart device and complete activation within 1 minute; check for light interference |
