LJ6A3-1-Z/BX Inductive Proximity Sensor NPN NO, 1mm Detection, 10-30VDC, 300mA

This sensor features a 3-wire NPN normally open (NO) output. The standard wiring is: Brown wire to +V (10-30VDC), Blue wire to DC common (0V), and Black wire as the switched output. When a metal target is detected, the NPN transistor switches, connecting the Black output wire to the Blue common wire (current sinking).

As a shielded inductive sensor, the LJ6A3-1-Z/BX is primarily designed to detect ferrous metals (steel, iron) at its rated 1mm distance. It can also detect non-ferrous metals like aluminum and copper, but the effective sensing distance will be reduced, typically by 30-50%, due to lower conductivity and permeability.

The 'detection distance' (1mm) is the nominal sensing range under standard conditions. The 'setting distance' (0-0.7mm) is the recommended installation gap between the sensor face and the target to ensure reliable switching and account for manufacturing tolerances, temperature effects, and supply voltage variations.

Yes, with its IP65 rating, the sensor is protected against dust ingress and low-pressure water jets from any direction. This makes it suitable for use in most industrial settings, including machine tools, packaging lines, and outdoor enclosures, though it is not submersible.
