Product Description

The LJ18A3-8-Z/AX sensor is an NPN NC proximity switch designed for industrial applications like automation, machinery, and material handling. As an LJ18 inductive proximity sensor, it features an 18mm detection range, detecting ferrous metal targets with high repeatability. Operating within 10-30V DC, it supports a temperature range of -25°C to +70°C, ensuring reliability in harsh environments. The NPN normally closed (NC) output configuration delivers up to 200mA current, compatible with PLCs or control modules via direct wiring. Its rugged stainless-steel housing offers IP67 protection against dust and water. While optimized for metal sensing, it is unsuitable for non-metallic objects. Key advantages include robust build, EMI resistance, and long service life. The LJ18A3-8-Z/AX requires no batteries or displays, functioning as a passive sensing component for streamlined integration.
