The BES M12ME-NSC40B-S04G-003 is an M12 inductive proximity sensor with an NPN normally open output, detecting metal targets at a rated operating distance of 4mm. It is designed for flush mounting and operates on a 10-30 VDC supply, connecting via an M12x1 4-pin male A-coded connector. The brass housing and IP68 rating suit installation in industrial environments where exposure to dust and moisture is expected, with a switching frequency of 2500 Hz supporting fast detection cycles.
