Wiring diagram

Remark:
The sensors are equipped with shielded cables, Q is the switch output.
RS-485 output: The black and white lines A and B must not be reversed and A and B cannot be short-circuited with the power line "﹢, -".
Analog output: The gray line Ia cannot be short-circuited with the power line "﹢, -". There is a small shielded wire, which shall not be in short-circuit connection with the analog output wire, but recommended to be grounded or not grounded.

Installation of laser distance sensor

Tips: Working Principle of Laser Distance Sensor.

When the laser distance sensor is working during the transmission time, the laser diode is first aimed at the target and emits laser pulses. The laser light is scattered in all directions after being reflected by the target. Part of the scattered light returns to the sensor receiver and is imaged on the avalanche photodiode after being received by the optical system. The avalanche photodiode is an optical sensor with an internal amplification function, so it can detect extremely weak light signals. Record and process the elapsed time from when the light pulse is sent to when it is received, and then the distance to the target can be determined. Transit time Laser sensors must measure the transit time extremely accurately because the speed of light is too fast.
