Generic LJ18A3-8-Z/EX Inductive Proximity Sensor, 6.4mm Detection Range, 2-Wire DC NO, 10-36V, IP65

This inductive proximity sensor is specifically calibrated to detect ferrous metals, primarily iron and steel. The sensing distance of 6.4mm is guaranteed for these materials. Non-ferrous metals like aluminum or copper will have a significantly reduced effective sensing range and are not the intended detection target for this model.

Wiring is straightforward due to the 2-wire design. Connect the brown wire to the positive DC supply voltage (10-36V) and the blue wire to the ground/common of your load (e.g., a PLC digital input). The sensor acts as a switch in series with the load. When a metal target is detected, the internal switch closes, completing the circuit and allowing current to flow to your controller.

Yes, the 'non-shielded' or flush-mountable design of the LJ18A3-8-Z/EX allows it to be installed flush in a metal mounting bracket without a gap. This design minimizes the required mounting space and enables side-by-side installation of multiple sensors. Ensure the sensing face is flush with the mounting surface for optimal performance.

The operating voltage (10-36V DC) is the electrical power required for the sensor's internal electronics to function. The detection range (6.4mm) is a mechanical specification indicating the maximum distance from the sensor's face at which a standard iron target will reliably trigger the output switch. These are independent parameters; the sensor will operate across the full voltage range while maintaining the specified 6.4mm sensing distance.
