    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.

    Tips: Safety Warning of Laser Distance Sensor.

    1. Do not use in an environment with flammable,explosive or corrosive gases.
    2. The RS485 communication line should not be too long.
    3. Do not disassemble,repair or modify this product without authorization.
    4. This product is dangerous, please do not look directly at the laser or observe the optical system through the lens.
    Existing reviews of Laser Distance Sensor, 85mm
    Excellent laser distance sensor!
    After using my original laser sensor for a while, the measurement error became worse. I was quite surprised to buy a laser distance sensor from ATO this time. This long distance laser sensor is lightweight and very easy to carry. The most important thing is that the distance measurement is fast and accurate. What makes me the most impressed is that even in the case of rain and interference, the range error of the sensor is still small. Sincerely recommend it!
