LJ18A3 Inductive Proximity Sensor

Description

LJ18A3 Inductive Proximity Sensor – NPN DC 6V-36V 3-Wire for CNC & 3D Printer Limit Switch

Detect metal targets with this LJ18A3 Inductive Proximity Sensor. Featuring an 8mm sensing distance and M18 threaded body, this sensor provides reliable non-contact detection for CNC limit switches, homing, and 3D printer applications.

The Inductive Proximity Sensor outputs a clean NPN signal to your controller. It operates on DC 6V-36V and uses 3-wire connection for easy wiring. Unlike mechanical switches, it has no moving parts to wear out — ideal for dusty workshop environments.

Ideal for CNC routers, 3D printers, and industrial equipment, this Inductive Proximity Sensor installs easily with standard mounting nuts. Whether you’re building a new machine or replacing a worn sensor, this switch delivers dependable performance.
