Description
Infrared Safety Beam System for Garage Doors & Sectional Door Safety
Product Overview
Infrared Safety Beam System for Garage Doors & Sectional Door Safety

The JUTAI CL20-8L Infrared Safety Beam System is a dedicated protective solution for garage doors and sectional doors. It forms an 8-beam invisible infrared barrier between the emitter and receiver, instantly triggering door reversal or stopping when personnel, vehicles, or objects intrude the detection area. With IP67 protection and rugged aluminum alloy construction, it delivers reliable anti-pinch safety for residential, commercial, and industrial garage/sectional doors.

Core Specifications
Parameter Specification
Model CL20-8L
Product Type Infrared safety beam system (safety light curtain)
Working Voltage DC12-24V
Working Current Transmitter: <65mA @DC12V; Receiver: <20mA @DC12V
Output Configuration NO/NC relay output (default NO, configurable to NC); COM terminal included
Protection Rating IP67 (dustproof + waterproof)
Housing Material Aluminum alloy
Operating Range (Emitter to Receiver) 1-8m
Maximum Protection Height 1729mm
Number of Photocells 8 beams
Cable Length Transmitter: 8m; Receiver: 4m
Connector Type Transmitter: 5-pole M8 male connector; Receiver: 4-pole M8 male connector
Operating Temperature -20°C ~ +60°C
Key Function Garage/sectional door anti-pinch protection + Blanking Mode (anti-false alarm)
LED Status Indicators Transmitter: Steady blue (normal); Fast-flashing red (voltage <9V or >28V)
Receiver: Steady red (blocked); Steady blue (unblocked); Flashing blue (misalignment)
Installation Hole Dimensions (Unit: mm) 14, 29, 75, 80, 175, 19.7, 21.4, 259
Key Advantages
  • Targeted Anti-Pinch Protection: Detects people, pets, vehicles, or objects near garage/sectional doors, triggering immediate door reversal to prevent pinching or crushing. 8-beam full coverage eliminates safety blind spots, adapting to standard and large-sized garage/sectional door openings.
  • Blanking Mode for False Alarm Prevention: Blocks the first channel without triggering safety responses, adapting to sectional door panel gaps and garage door structural characteristics. Avoids unnecessary interruptions during normal door closure while retaining protection against unintended intrusions.
  • Rugged & Environmentally Adaptable: IP67 protection resists rain, dust, and outdoor elements, suitable for indoor/outdoor garage doors and industrial sectional doors. Wide temperature range (-20°C ~ +60°C) ensures stable operation in cold winters, hot summers, or temperature-variable industrial settings.
  • Easy Installation & Integration: Color-coded wiring simplifies connection to garage/sectional door control systems. Adjustable mounting brackets fit various door frame structures; 8m/4m cables allow flexible positioning. Intuitive LED indicators enable quick status checks without professional tools.
Wiring Guide
Component Wire Color Function Notes
Transmitter Red DC12-24V Positive Power Supply Connect to door control system's power positive terminal
Transmitter Black Ground (GND) Connect to power negative terminal
Transmitter Green/Yellow/White Reserve No connection required for basic use
Receiver Red DC12-24V Positive Power Supply Same as transmitter power connection
Receiver Black Ground (GND) Same as transmitter ground connection
Receiver Green NO/NC Output (Default NO) Connect to door control system's safety signal input
Receiver Yellow Configurable NC Activate via Blanking Mode setup
Receiver 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 system.
  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.
Application Scenarios
  • Residential garage doors (single-car, double-car)
  • Commercial garage doors (parking facilities, retail back entrances)
  • Industrial sectional doors (factories, warehouses, loading docks)
  • Cold storage sectional doors (refrigerated warehouses, freezer rooms)
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
System 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.
  • Regularly wipe emitter/receiver lenses with a dry, soft cloth to remove dust, dirt, 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).
  • For outdoor installation, ensure the device is shielded from extreme weather (e.g., heavy rain, snow) to extend service life.
