Balluff BES 516-3019-S4-C Inductive Proximity Sensor

Balluff BES018Y (BES 516-3019-S4-C) is a cylindrical, non-flush inductive proximity sensor with a Ø12 x 70 mm stainless‑steel body designed for metal detection and a 4 mm nominal sensing distance, making it suitable for tight spaces where mounting depth is limited. It uses a 3‑wire DC configuration and provides a PNP normally closed output, powered from 10 to 30 V DC, with an M12x1 4‑pin S4 connector and a PA12 sensing face for robust sensing in industrial settings. The unit is IP68 protected and rated for an ambient temperature range of -40 to 85 °C, enabling operation in harsh environments and washdown processes. Electrical performance includes a maximum load current of 200 mA, ripple up to 15%, no-load current around 1–8 mA, and a switching frequency up to 1,500 Hz, with built‑in short‑circuit and polarity‑reversal protection.
