BurookHi Norman... I just remembered i didn't let u know.... everything worked out we made both the wired and the remot control opening work... they loved the item (assuming it will hold its own for the next 10 years or so) -
KiranYes I don’t doubt you. Jutai is one of the most confident companies I came across in China

Product Description
Photoelectric Safety Device for Automated Doors with Blanking Mode Function
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.
Core Specifications
| Parameter | Specification |
|---|---|
| Model | CL20-8L |
| Product Type | Photoelectric safety device (safety light curtain) |
| Working Voltage | DC12-24V |

| Operating Temperature | -20°C ~ +60°C |
| Key Function | Automated door anti-pinch protection + Blanking Mode (anti-false alarm) |
| LED Status Indicators | Transmitter: Steady blue (normal operation); Fast-flashing red (voltage <9V or >28V) Receiver: Steady red (object/personnel blocked); Steady blue (no obstruction); Flashing blue (first power-on, emitter-receiver misalignment) |
| Installation Hole Dimensions | Refer to size parameters: 14mm, 80mm, 175mm, 259mm, 29mm, 75mm, 19.7mm, 21.4mm (unit: mm) |
Key Functions & Advantages
- Blanking Mode: Anti-False Alarm for Automated Doors - Specifically designed for automated door gaps where blocking the first channel won't trigger safety responses, adapting to structural characteristics of automated doors
- Targeted Anti-Pinch Protection - 8-beam light grid covers full door height (1729mm), detecting hands, limbs, or objects to prevent accidents with instant response
- Rugged & Reliable Performance - IP67 protection withstands dust, water, and temperature extremes from -20°C to +60°C with durable aluminum alloy housing
- Easy Installation & Intuitive Operation - Color-coded wiring, adjustable mounting, and visual diagnostics simplify setup and maintenance
Wiring Guide
| 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 |
Critical Warning: Do NOT connect NO/NC terminals (Green/Yellow wires) to power supply positive terminal—this will permanently damage the optical relay.
Application Scenarios
- Industrial Automated Doors - Fast doors, roller shutter doors, sectional industrial doors in factories, warehouses, and logistics centers
- Commercial Automated Doors - Automatic swing doors, sliding doors in shopping malls, office buildings, and retail stores
- Special Environment Automated Doors - Cold storage automated doors, clean room fast doors, outdoor automated doors resistant to temperature extremes
- Logistics/Loading Dock Doors - Automated loading dock doors, material transfer area doors for high-frequency operations
Troubleshooting
| 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 |
