Balluff BES-516-327-S4-C Inductive Proximity Sensor

Balluff BES-516-327-S4-C is a cylindrical inductive proximity sensor in an M30 housing (Ø30 x 83 mm, M30x1.5) with a 10 mm sensing range and flush-mount installation, designed to detect metal objects as they pass within a compact, rugged package. It operates from 10–30 VDC and provides a PNP normally-open (NO) switching output through an M12 4-pin connector, with an IP68-rated enclosure and a switching frequency up to 300 Hz to handle continuous production-line cycling. A brass, nickel-plated housing protects a PA12 sensing face suitable for harsh factory environments, and the device is rated for -25 to 70 C, complying with CE, cULus, EAC, and WEEE standards. Common applications include position sensing on conveyors, tool changers, and automated manufacturing lines where a robust, flush-mount sensor with easy cable-connection is advantageous. With its standard form factor, reliable inductive sensing, and availability from Balluff's global catalog, the BES-516-327-S4-C is a practical choice for retrofit projects seeking durable, maintenance-friendly metal-detection capability.
