LASER LIGHT SAFETY SENSOR

NEW VERSION M-227LF 4-Beam Laser Safety Sensor For Swing Door

This laser safety sensor 227LF is a new version based on 227L to adapt to more occasions and demands. It utilize time-of-flight (ToF) principle to detect whether the objects or humans in the moving range to protect the pedestrian’s security.

227LF is used for swing door, revolving door, and fix on the top edge of the door leaf. High quality and performance safety laser scanners, every sensor is a total of four beams light, each beam light is 100mm light spots.
