CANBO®
CNB-903 Laser Safety Curtain Sensor


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.

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

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


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.

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.

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

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.
