    Tips: The current and voltage of proximity sensor

    1. No-load current (IO): The current consumption measured in no-load condition.
    2. Operating current (IL): The maximum load current measured in the condition of proximity sensor continuously working.
    3. Instantaneous current (IK): The permissible current that appears in a short time and doesn't damage the proximity sensor, when the proximity sensor is closed.
    4. Residual current (IR): The current that goes through the load, when the proximity sensor is disconnected.
    5. Operating voltage (UB): It means the maximum and minimum value of the operating voltage. In this range, the proximity sensor can ensure the safe operation.

    ATO will use a proximity sensor and a digital counter to count number in the video.

    Existing reviews of Proximity Sensor, Inductive, M18, 3 Wire, 120V
    How is it powered?
    Is this sensor measuring a distance and sending out the data or is it only sending a signal when a specific distance is achieved? How is it powered? I am looking for a small assembled prox sensor to detect when an object is 1-2 inches away.

    ATO Responded
    It's not sending out data. Here is the supply: voltage  DC 12-24V (6-36V), AC 110-220V  (90-250V).
