Safety Light Barrier for High Speed Doors with CE Certification and Anti Pinch Function 0


Safety Light Barrier for High Speed Doors with CE Certification and Anti Pinch Function

The JUTAI CL20-8L Safety Light Barrier is a specialized protective device engineered to deliver reliable anti-pinch safety and intrusion detection for high speed doors in industrial and commercial settings. By forming an invisible light beam grid between its emitter and receiver, it instantly triggers safety responses—such as door reversal or stopping—when people, objects, or equipment interrupt the beams, effectively preventing pinching accidents and operational hazards.
Certified CE and compliant with safety standards, this light barrier combines rugged performance with user-friendly design, making it an indispensable safety component for high speed doors in factories, warehouses, logistics centers, and other high-traffic industrial environments.

Core Features Tailored for High Speed Door Safety

1. CE-Certified Anti-Pinch Protection

With CE certification validating its safety performance, the light barrier is designed specifically to address anti-pinch risks of high speed doors. It detects intrusions within milliseconds, ensuring the door responds instantly to avoid crushing or pinching personnel, tools, or goods in the door’s path.

2. IP67 Waterproof & Dustproof Durability

Crafted with a sealed aluminum alloy shell, the light barrier achieves IP67 protection rating, resisting water immersion, heavy dust, and industrial contaminants. It maintains stable performance in outdoor installations, dusty workshops, or humid environments—ideal for long-term use with high speed doors exposed to harsh conditions.

3. Blanking Mode to Avoid False Alarms

Equipped with a specialized Blanking function, blocking the first channel won’t trigger safety responses. This mode is optimized for high speed door gaps, where sequential beam blockage during normal door closure is expected, eliminating false alarms while retaining full protection against unintended intrusions.

4. Rapid Response & Precise Detection

Featuring 8 photocells and a maximum protection height of 1729mm, the light barrier covers large high speed door openings comprehensively. With a sensitive detection design, it identifies objects and personnel quickly, matching the fast operational speed of high speed doors to ensure no safety lag.

5. Wide Temperature Adaptability

Operating reliably within a temperature range of -20°C to +60°C, the product thrives in diverse environments—from cold storage facility high speed doors to outdoor-installed doors exposed to seasonal temperature fluctuations, without performance degradation.

6. Intuitive LED Status Monitoring

Clear LED indicators on both emitter and receiver provide real-time operational feedback for easy troubleshooting:
  • Transmitter: Steady blue light (normal operation), fast-flashing red light (voltage irregularity: <9V or >28V).
  • Receiver: Steady red light (beam blocked/intrusion detected), steady blue light (no obstruction), flashing blue light (alignment required after first power-on).

7. Easy Installation & Seamless Integration

Features standard connectors (transmitter: 5-pole M8 male; receiver: 4-pole M8 male) for straightforward wiring. Color-coded cables (DC12-24V power supply) simplify setup, with red for positive, black for ground, and green for NO/NC output (default NO), ensuring compatibility with most high speed door control systems.

Primary Applications

  • Industrial High Speed Doors: Anti-pinch protection for fast-closing doors in manufacturing plants, distribution centers, and logistics hubs.
  • Roller Shutter High Speed Doors: Safety monitoring for high-speed roller shutters in warehouses, industrial facilities, and retail back entrances.
  • Cold Storage High Speed Doors: Reliable performance in low-temperature environments, preventing door closure on personnel or equipment.
  • Workshop High Speed Doors: Protection against intrusions during rapid door operation in production areas with frequent personnel and equipment movement.

Troubleshooting & Usage Guidelines

Fault Symptoms Solutions
Slow Flashing Lights After Power On The emitter and receiver are misaligned; readjust to ensure precise beam alignment.
Red Light Flashing Fast (Transmitter End) Voltage is outside the 9V-28V range; check and stabilize the power supply.
Light Barrier Normal But No Anti-Pinch Action Wiring error; verify connections (ensure NO/NC is not connected to the power supply positive terminal to avoid optical relay damage).
Unable To Enter Blanking Mode 1. Light leakage during door descent causes discontinuous beam blocking. 2. The bottommost beam is blocked. 3. The door or obstruction fails to meet the minimum continuous blocking distance.

Usage Caveats

  • Keep connecting cables away from high-voltage or high-current conductors to avoid interference.
  • Wipe the emitter and receiver lenses with a dry, soft cloth regularly to prevent dirt from affecting detection.
  • Do not bend or twist the light barrier, and avoid direct sunlight or other infrared light sources shining on the receiver.
  • Ensure the door or obstruction used for Blanking mode meets the minimum continuous blocking distance requirement.
