Pepperl+Fuchs NCN4‑12GM35‑NO Inductive Proximity Sensor
Product Overview
The Pepperl+Fuchs NCN4‑12GM35‑NO is a 2‑wire NAMUR‑type inductive proximity sensor. It detects the presence of metallic objects without physical contact, converting metal target proximity into NAMUR‑standard current signal output. Mainly matched with intrinsic safety barriers, it performs position detection, object counting and equipment status monitoring in explosive‑hazard industrial zones. Widely deployed on automated machinery for non‑contact metal target sensing tasks.
Core Advantages
✅ NAMUR intrinsically‑safe output: Designed for hazardous explosive areas, compatible with safety barriers, meets ATEX / IECEx explosion‑proof standards, supports SIL 2 functional safety application. ✅ Stainless‑steel threaded housing: M12 cylindrical metal body, robust mechanical resistance, non‑flush mounting style, rated IP67 tightness for harsh workshop environments. ✅ Reverse‑polarity & short‑circuit protection: Built‑in circuit protection, reduces installation wiring damage risk; omnidirectional yellow LED status indicator for on‑site quick status check. ✅ Stable detection performance: 4 mm rated sensing distance, low hysteresis, up to 800 Hz high‑frequency switching response, reliable detection for different metal materials with defined reduction factors. ✅ Wide temperature adaptability: Operates stably from ‑25 °C to +100 °C, fits high‑temperature production field conditions.
