The Pepperl+Fuchs NBN8-12GM50-E2 is an inductive proximity sensor in a M12 x 1 threaded brass housing with a rated operating distance of 8 mm (non-flush installation). It has a PNP normally-open 3-wire DC output, an operating voltage of 6 … 36 V, a switching frequency of up to 1650 Hz, and a 2 m PVC cable, per the Pepperl+Fuchs data sheet (item number 326161-0054).
Decode the model: NB = inductive sensor, N = non-flush, 8 = 8 mm operating distance, 12GM50 = M12 threaded metal housing (GM50 design), E2 = PNP NO output. The NBB/NBN GM50 sensors are rated for harsh environments with high shock resistance and an extended temperature range, and are standard on packaging, automotive and material handling lines.

Compatibility and replacement
Replace like-for-like: same thread (M12), output (PNP NO), installation (non-flush) and distance (8 mm). Wiring: brown L+, blue L-, black output. If the old sensor is NPN, it is a different model; send us its label and we will match it.
Frequently asked questions
Flush or non-flush, what is the difference?
A flush sensor can be mounted level with the metal around it; a non-flush sensor needs free space around the sensing face but has a longer range for the same size.
Are the mounting nuts included?
Yes. Pepperl+Fuchs lists two self-locking nuts in the scope of delivery.
