Pepperl+Fuchs NBN40-U4-E2-V1 Inductive Proximity Sensor

The Pepperl+Fuchs NBN40-U4-E2-V1 Inductive Proximity Sensor detects metal objects without contact, making it essential for precise, maintenance-friendly sensing in industrial automation across conveyors, packaging machines, assembly lines, and material handling equipment, and for reliable object detection and improved system accuracy. It features a 40 mm non-flush sensing distance, inductive metal detection, a PNP normally open output, 10–30 VDC supply, IP67 protection, a rectangular U-shaped housing, and an M12 connection (V1), with mounting by bracket or surface; it uses the MPN NBN40-U4-E2-V1 (203107) and operates from -25°C to 70°C with standard industrial switching frequency. In practical use, it serves positioning, counting, and machine-safety functions in manufacturing plants, automotive production lines, and logistics environments; common replacements include Pepperl+Fuchs NBN25-U4-E2-V1, Omron E2Q5-N40, and Sick IME30-40NPSZC0K.
