Balluff BES 516-370-G-E5-Y-S4 Inductive Proximity Sensor

The Balluff BES 516-370-G-E5-Y-S4 is a shielded inductive proximity sensor with a 4 mm nominal sensing distance, designed for flush mounting in metal frames via an M12x1 4‑pin connector. This 3‑wire DC device features a PNP normally‑closed output and operates on 10–30 VDC (commonly powered from 24 VDC), delivering up to 130 mA to a load with built‑in short‑circuit and reverse‑polarity protection. It is rated IP67 and specified for harsh environments from −25°C to 70°C, with a PA12 sensing face and a housing intended for mounting in steel, making it well suited for compact end‑of‑travel or position sensing in metal‑enclosed automation areas. The nominal sensing distance is 4 mm (Sn), with guaranteed operation from 0 to 3.2 mm (Sa) and a repeatability on the order of a few percent, ensuring reliable switching in repetitive industrial cycles.
