Infrared Laser Safety Light Curtain for Automatic Swing Doors, M-903 Anti-Pinch Grating Sensor with Hand Protection and Collision Detection
M903 Infrared Laser Safety Light Curtain for Automatic Swing Doors

-
Intelligent cutting
The laser beam intelligently cuts the position of the door frame without self-sensing.

-
Angle adjustment
Installation angle is adjustable from 5° to 10°. Turn the knob clockwise, the angle becomes smaller, turn the knob counterclockwise, the angle becomes larger.

-
Function switching
Switching the safety presence and anti-collision functions by DIP switch 1 to achieve, easy to operate.

-
User-friendly debugging
Scanning range in all 7 levels, push once, one buzzer voice, scanning range will increase or decrease by 5cm. When buzzer sounds 2 times, the adjustment has reached the limit range.

-
Simple wiring, clean installation
Compact and delicate appearance. After the main and secondary machine are connected, only one of them needs to be connected with the door opener.

-
Stable, anti-interference
Use the "precise and fast" features of the laser, with the Intelligent Speed Adaptation System(ISAS), to ensure long-term stable operation and reliable security protection.

-
6-beam, fully coverage protection
6 laser beams, detecting range covers the entire door leaf, ensuring precise protection for personnel at any position.

-
Accurate detection
Adopt Time of Flight(TOF) technology, accurately detect the presence of the objects or human body, which as the function of safety presence, anti-collision and safety detection.
