Inductive Proximity Sensor Switch

Description

Inductive Proximity Sensor Switch – LJ18A3-8-Z/BX NPN 18mm CNC Limit Combo for QueenAnt PRO

Upgrade your CNC with this Inductive Proximity Sensor Switch. Based on the LJ18A3-8-Z/BX model, this NPN sensor delivers reliable non-contact detection for limit and homing applications on QueenAnt PRO machines.

Featuring an 18mm tubular M18 housing with 8mm detection distance, it operates on DC 6-36V and outputs a clean NPN NO signal to your controller. Unlike mechanical switches, this sensor has no moving parts to wear out — making it ideal for dusty workshop environments.

The combo includes a mounting bracket and connectors for straightforward installation. Compatible with GRBL, Mach3, and most CNC controllers, this Inductive Proximity Sensor Switch is a direct replacement for worn limit switches or a clean upgrade for new builds.
