Three Wire Micro Inductive Proximity Sensor, IP68 Waterproof Metal Detecting Switch with 2m Cable, Selectable NPN/PNP NO NC, Model NPN NC O3

This miniature O3 inductive proximity sensor is an industrial-grade metal detection switch built for automated equipment, conveying lines and precision machinery. Adopting advanced inductive sensing technology, it accurately identifies ferrous metal objects without physical contact, delivering reliable non-contact detection to avoid mechanical wear.

The sensor features a robust fully sealed IP68 waterproof and dustproof structure, capable of stable operation in damp, dusty, splash-prone workshop environments without short circuit or signal failure risks. It comes with a 2-meter long wear-resistant cable, offering ample length to meet different equipment wiring demands and simplify layout assembly.

Standard three-wire circuit design supports customizable output types including NPN, PNP, Normally Open (NO) and Normally Closed (NC). This specific version is NPN NC, which cuts off the signal when metal targets enter the sensing area, perfectly matching PLC, relay and controller signal input terminals.

Its tiny O3 micro body fits tightly into confined installation positions where standard-size sensors cannot be mounted. Internal anti-interference circuit effectively filters electromagnetic interference from motors and power supplies, ensuring consistent, accurate detection during long-duration continuous operation.

Widely applied in mechanical automation, packaging machinery, CNC equipment, conveyor belt counting and position limiting detection. Simple wiring and plug-and-play operation greatly reduce on-site debugging time for industrial maintenance...
