    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.

    Simple use and accurate
    I believe this is the best laser distance sensor I bought this year for its affordable price and convenience. I can say that after testing it out today, I find it’s very easy to read and use. Multiple functions to measure distance and its accuracy definitely make my work much easier. I highly recommend it!
