The Pepperl+Fuchs NBB5-18GM50-E0-V1 Proximity Sensor is an inductive proximity sensor designed for non-contact detection of metallic objects in industrial automation. It uses an M18 threaded housing with flush-mounting design, built from nickel-plated brass, and offers a 5 mm sensing distance powered by 10–30 VDC through a 4-pin M12 connector. It provides an NPN normally open, 3-wire output, supports reverse-polarity and short-circuit protection, switches up to 800 Hz, and is rated IP67 with an operating temperature of -40°C to +85°C.
