    Wiring diagram

    Wiring diagram of laser distance sensor

    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

    Installation of laser distance sensor

    Tips: Precautions of Laser Distance Sensor.

    Please do not use in the following environment.

    1. Direct sunlight.
    2. Places with high humidity or easy condensation.
    3. Places containing corrosive gases.
    4. Places subject to severe vibration or shock.

    Connection and installation

    1. Do not use the sensor in an unstable state immediately after the power is turned on,it is recommended to test after 30 minutes of power on to achieve desired accuracy. Be sure to carry out wiring with the power off. If a wrong wiring occurs, it will cause a malfunction.
    2. Please make sure that the power supply voltage is within the rated value before powering on.
    Please use rated load.
    3. The RS485 signal line cannot be short-circuited with the power supply,otherwise it may cause product failure or damage the product.
    4. When installing the sensor,do not subject the sensor to severe external forces(such as hammering,etc), as this may damage the sensor performance.
    5. Do not bend the lead out of the cable with excessive force,and avoid applying pressure such as pulling.


    1. Thinner will corrode the surface of the filter, it is best to avoid using it.
    2. If there is dust on the surface, please wipe it gently with dry dust-free cloth.

    Accurate laser distance sensor
    Is there anything I need to be aware of for normal use?

    ATO Responded
    1.Make sure the weather environment is good. There should be less dust and floating particles visible in the air.
    2.Try not to use the laser distance sensor in rainy weather, because the water will cause the refraction of the laser dispersion, affecting the results of ranging and ranging range.
    3.Rangefinder is not a plaything. Careful use can extend the service life.
