Description

The LJ12A3-4-Z/BY is an M12 inductive proximity sensor for detecting metal without contact. Its PNP normally-open output switches on when a suitable metal target enters the nominal 4 mm sensing range. Use it for position sensing and end-stop detection with a compatible DC control input.

Wiring & getting started

  1. Check the input and wiring

    Confirm the diagram on the supplied sensor. Standard three-wire PNP wiring is brown to positive, blue to 0 V and black to the compatible input or load, with its return at 0 V.

  2. Mount and power it

    Keep the blue sensing face proud of surrounding metal. With power off, connect a regulated DC supply within the stated range. Apply power and bring an iron target within the set distance.

  3. Check detection

    The input should activate near the target and release when it is removed. Allow for a shorter detection range with non-magnetic metals.

Note: The PNP output can approach the sensor supply voltage. Use a suitable interface for 3.3 V or 5 V logic; do not connect the output directly to a microcontroller GPIO. Replacing an NPN sensor requires checking the controller input and wiring.
