Pepperl+Fuchs NBB4‑12GM50‑E0 Proximity Sensor (IP65)

📌 Product Overview

This Pepperl+Fuchs NBB4‑12GM50‑E0 is a 3‑wire DC inductive proximity sensor. It detects metallic target objects without physical contact. It sends digital switching signal to PLC / industrial controller for object presence detection, position confirmation, parts counting and equipment limit signal in industrial automation machines. Non‑contact detection avoids mechanical wear, widely deployed for automatic machine status feedback.
