Laser sensor with rectangular ABS housing (22*11*31mm), 1mm spot size, diffuse reflection/through beam detection mode and NPN/PNP NO/NC output mode for selection.

Specification:

Note: The detection range of diffuse reflection laser sensor can be adjusted by the knob (Clockwise rotation for adding distance, anticlockwise rotation for reducing distance). The detection range of through beam laser sensor can be adjusted by the distance of projector and receiver.

Tips: Application of laser sensor - Automatic Collision Avoidance System
In general, most existing automatic collision avoidance systems use laser distance sensors. The laser sensor uses a laser beam to identify the distance between a car and a target car driving in front or behind it in a non-contact manner. When the distance between the cars is less than the predetermined safe distance, the automatic collision avoidance system of the car makes an emergency brake on the car, or issues an alarm to the driver. The car collision avoidance system can make real-time judgment and response to the car driving by integrating the target car speed, car distance, car braking distance, response time and other factors, which can greatly reduce driving accidents. Especially when used on the highway, the advantages of the car collision avoidance system will be more obvious.
