Description
Photoelectric Safety Guard for High Speed Doors with 8-16 Beam Options
Product Overview
Photoelectric Safety Guard for High Speed Doors with 8-16 Beam Options

The JUTAI CL Series Photoelectric Safety Guard is a specialized protective solution engineered for high speed doors, offering flexible 8-beam or 16-beam configurations to match different safety requirements. It forms an invisible light grid between the emitter and receiver, instantly triggering door reversal or stopping when personnel, objects, or equipment intrude—effectively preventing pinching, crushing, or collision accidents in industrial and logistics environments. With IP67 protection and rugged aluminum alloy construction, it delivers reliable performance even in harsh conditions.

Core Specifications

Installation Hole Dimensions (Unit: mm) 14, 29, 75, 80, 175, 19.7, 21.4, 259
Key Advantages
  • 8-16 Beam Flexible Configuration: 8-beam option balances safety and cost for standard high speed door openings, while 16-beam option delivers high-precision detection with denser light grid for large doors or high-risk areas.
  • High Speed Door Compatibility: ≤20ms rapid response time matches fast door operation, with Blanking Mode adapting to door gap structures to avoid false alarms.
  • Rugged & Environmentally Resilient: IP67 protection withstands dust, water splashes, and temporary immersion, with wide temperature range for stable operation in various environments.
  • Easy Installation & Integration: Color-coded wiring simplifies connection, adjustable mounting brackets fit various frames, and intuitive LED indicators enable quick status checks.
Wiring Guide
Component Wire Color Function Notes
Transmitter Red DC12-24V Positive Power Supply Connect to stable power supply; avoid overvoltage/undervoltage
Black Ground (GND) Connect to power negative terminal; ensure reliable grounding
Green/Yellow/White Reserve No connection required for basic use
Receiver Red DC12-24V Positive Power Supply Same as transmitter power connection
Black Ground (GND) Shared ground with transmitter
Green NO/NC Output (Default NO) Connect to door control system's safety signal input
Yellow Configurable NC Activate via Blanking Mode setup
White COM (Common Terminal) Matching terminal for NO/NC output
Critical Warning: Do NOT connect NO/NC terminals to the power supply positive terminal—this will damage the optical relay.
Blanking Mode Activation Steps
  1. Complete wiring and power on the device.
  2. Within 1 minute of power-on, touch the receiver's Green wire to its GND (Black wire) five times.
  3. Receiver's Red light blinks to confirm activation: Yellow wire switches to NC mode, Blanking Mode enabled.
Model Configuration & Application Scenarios
Model Beam Quantity Protection Height Target Applications
CL05-8L/16L 8/16 500mm Small high speed doors, access doors in logistics centers
CL10-8L/16L 8/16 1000mm Medium-sized high speed doors, retail back entrance doors
CL15-8L/16L 8/16 1500mm Warehouse high speed doors, production line access doors
CL20-8L/16L 8/16 2000mm Large industrial high speed doors, cold storage fast doors
CL25-8L/16L 8/16 2500mm Extra-large high speed doors, loading dock doors
Troubleshooting
Fault Symptoms Possible Causes Solutions
Receiver's blue light flashes (power-on) Emitter and receiver misalignment Readjust positions to ensure parallel alignment
Transmitter's red light flashes fast Power supply voltage <9V or >28V Stabilize power supply to meet DC12-24V requirements
Safety guard works, but door has no anti-pinch action Wiring error Recheck wiring against the guide; ensure correct connection to door control system
Unable to enter Blanking Mode 1. Light leakage during door descent
2. Bottommost beam blocked by debris
3. Door/obstruction fails to meet minimum continuous blocking distance		 1. Fix door sealing to prevent light leakage
2. Clear debris blocking the beam
3. Adjust door/obstruction to meet distance requirements
Usage & Maintenance Caveats
  • Keep cables away from high-voltage conductors and door machinery to avoid damage or interference.
  • Regularly wipe emitter/receiver lenses with a dry, soft cloth to remove dust or condensation.
  • Do not bend, twist, or pull cables forcefully; avoid scratching infrared lenses.
  • Prevent direct sunlight or infrared light sources from shining on the receiver (avoids false triggers).
  • Periodically test the anti-pinch and Blanking Mode functions to ensure normal operation.
