Balluff BES 5216-370-S4-C Inductive Proximity Sensor

The Balluff BES 516-370-S4-C is a flush-mount inductive proximity sensor in a rugged stainless‑steel housing that detects metallic targets with a 2 mm sensing distance. It operates from a 10–30 VDC supply and provides a PNP normally closed (NC) output through a 4‑pin M12 connector, simplifying wiring in tight spaces. The device measures Ø12 x 70 mm and uses a stainless‑steel body with a PBT sensing surface for durability in demanding environments. It carries an IP68 rating and a wide operating temperature range of -40 to 85°C, making it suitable for harsh industrial settings, conveyors, and presses. With a switching frequency up to about 3.5 kHz, it responds quickly to fast-moving parts on automation lines. Compliance includes CE, cULus, EAC, and WEEE markings, supporting integration into global systems. Typical applications include end-stop and position sensing, metal presence checks, and flush-mounted sensing where space is at a premium, such as packaging machines, robotic fixtures, and automated assembly lines. The BES 516-370-S4-C’s combination of compact dimensions, robust stainless‑steel construction, and reliable 10–30 VDC operation makes it a dependable choice for metal-detection tasks that require a discrete, non-contact switch.
