About this product
The LJ12A3-4-Z is a cylindrical inductive proximity sensor with a 12 mm threaded body and a 4 mm sensing distance. It detects ferrous metals such as iron and steel without physical contact, so it suits position detection, end-stop sensing and counting metal parts in machines and automation projects. It runs from 6 to 36 V DC and has a 3-wire cable.

How do I wire the sensor?
The three wires are brown for positive supply (V+), blue for negative supply (0 V / GND), and black for the signal output. Confirm whether your sensor is NPN or PNP and match the output logic to your controller's input before connecting.
Which materials does it detect?
It is designed to detect ferrous metals such as iron and steel within its 4 mm rated distance. Plastic, wood and glass are not detected, and non-ferrous metals like aluminium or copper give a shorter sensing range.
