    Documentation:

    How to Use:

    Wiring:

    • Connect the Brown wire (VIN) to the positive terminal of your DC power supply (6-36V).
    • Connect the Blue wire (GND) to the ground terminal.
    • Connect the Black wire (Signal) to the input of your control circuit or microcontroller.

    Installation:

    • Position the sensor near the target metal object within a 4mm range.
    • Ensure that non-metallic materials do not obstruct the detection path.

    Operation:

    • When a metallic object is detected within the range, the signal output will connect to the ground, activating your connected device or system.

    Testing:

    • Verify proper operation by introducing a metallic object within the detection range and observing the signal output.

    Package Includes:

    1 x LJ12A3-4-Z/BX Inductive Proximity Sensor NPN NO 4mm Detection Range M12
