Pepperl+Fuchs NBB4-12GM50-E0 Inductive Proximity Sensor 4 mm NPN NO IP65
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.
✨ Product Advantages (Core Features)
- Flush‑mount M12 cylindrical design, 4 mm nominal sensing distance, easy installation inside metal equipment frame
