JUTAI Safety Blanking Light Barrier 2m Length Glue Filling IP67 -30℃
CL20-8L8 Infrared Safety Light Curtain Sensor with Blanking Function for Industrial Doors
JUTAI Safety Blanking Light Barrier 2m Length Glue Filling IP67 -30℃
Product Introduction
The JUTAI safety light curtain CL20-8L8 establishes a protective shield by generating a beam of light between the emitter and the receiver. When an object or person enters the grid area, the light beam is interrupted, instantly triggering the safety system to take appropriate actions. It is commonly installed at critical points of devices such as doors, automatic doors, lifting equipment, and more, to promptly detect potential crushing risks. Widely utilized in industrial and commercial settings, it is an essential component of automation systems, particularly in situations demanding high safety standards.
Operating Modes
Blanking Mode
  • The safety light curtain is installed within the door gap
  • When the door closes normally, the light beams are sequentially blocked from top to bottom
  • This sequential blocking is recognized by the system as a normal door closing action
  • When the door is closing and an object obstructs the light beam, it causes the door to open immediately
Normal Mode
  • Installed on the inside and outside of the door
  • Light beams do not pass through when the door is closed
  • Regardless of which light beam is blocked, the system immediately outputs the door opening signal
Key Features
  • Comprises an emitter and a receiver
  • Operating range of 1-8 meters
  • Maximum protection height: 1820mm in both concealing and normal modes
  • Shell material: aluminum alloy
Product Advantages
  • Suitable for cold storage doors and humid environments (-25°C temperature range)
  • Does not require synchronous wire control box
  • Fast response speed: 0.03 seconds
  • Resistant to sunlight and electromagnetic interference
  • Supports customization (quantity)

Troubleshooting Guide
Fault Symptoms Solutions
Slow Flashing Lights After Power On The emitter and receiver are not aligned; readjust the alignment
Red Light Flashing Fast (Transmitter End) Voltage at transmitter end is below 9V or above 28V
Light Curtain Normal, But Door Has No Anti-pinch Action Wiring error
Unable To Enter Concealment Mode 1. Light leakage during door descent
2. Bottommost beam blocked
3. Minimum distance for continuous blocking not met
Installation and Usage Precautions
  • Keep connecting cables away from high voltage or high current conductors
  • Ensure lower door or obstructive object meets minimum distance for continuous blocking
  • Wipe emitter and receiver windows with dry, soft cloth to prevent dirt accumulation
  • Do not bend or twist the light curtain
  • Avoid direct exposure of sunlight or other infrared light sources to the receiver
  • Avoid scratching the surface of the infrared lenses
