    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.

    Existing reviews of Proximity Sensor, Inductive, M18, 3 Wire, 120V
    Maximum Mounting Torque
    We plan to purchase a proximity sensor (inductive, M18 thread, two-wire, 120V) from ATO, but we need to know its maximum mounting torque to determine if it is suitable for our application. Thank you very much for your help.

    Was this review helpful? Yes No (0/0)
    ATO Responded
    Regarding the ATOM18 specification inductive proximity sensor (SKU: ATO-PROS-I18) you mentioned, we recommend a maximum thread mounting torque between 20 N·m and 40 N·m, with around 30 N·m generally considered the safest.
    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).
