Balluff BES 516-324-G-E5-C-S4 Proximity Sensor

Balluff BES 516-324-G-E5-C-S4 is a rugged inductive proximity sensor designed for detecting metal targets with a 2 mm Sn sensing distance and a 10–30 VDC supply. It employs a 3-wire DC output in a PNP normally-open configuration and uses an S4 (M12) 4-pin connector for robust wiring. The sensor features an 8 mm diameter stainless-steel housing with a 55.5 mm length, PBTP sensing face, and IP68 protection, suitable for flush mounting in harsh industrial environments. Electrical specifications include 10–30 VDC supply, 200 mA rated operational current, Sn 2 mm, Sa 0...1.6 mm, hysteresis 15%, and a voltage drop around 2.5 V; it also provides short-circuit protection and reverse polarity protection. The listing title identifies this unit as PREOWNED, indicating used condition, and the BES-series sensor is commonly applied in conveyors, safety interlocks, and automation tasks where reliable metal sensing is required.
