Pepperl+Fuchs NBN4‑12GM50‑E2 Inductive Proximity Sensor

Product Overview

The Pepperl+Fuchs NBN4‑12GM50‑E2 is a 3‑wire PNP normally‑open cylindrical inductive proximity sensor. It detects metal objects without physical contact, converting metal target proximity into digital switching signal. This sensor performs position detection, object counting, limit monitoring and parts presence check for automated machinery. Widely deployed on conveyor lines, packaging machines and production equipment for general factory‑automation non‑contact metal‑sensing tasks.

Core Advantages

✅ IP68 high‑level enclosure protection: Brass nickel‑plated threaded housing, PBT sensing face, resistant to dust, water splash and moisture, fits harsh workshop environments. ✅ Reverse‑polarity & short‑circuit protection: Built‑in circuit safeguards, effectively avoid damage caused by wiring mistakes on site. ✅ Non‑flush mounting, 4 mm sensing distance: Stable detection performance, low hysteresis, reliable response for steel, brass, copper and aluminum workpieces. ✅ Yellow omnidirectional status LED: Visible from multiple angles for quick on‑site working‑status check. ✅ Wide operating‑temperature range: Works stably under‑40 °C ~ +85 °C, adapts to cold‑storage and high‑temperature workshop conditions. ✅ cULus certified: Meets international industrial standards, supports global machine‑building export projects.
