Balluff BES-516-325-S4-W Inductive Proximity Sensor

Balluff BES-516-325-S4-W is a weld-immune inductive proximity sensor housed in a cylindrical M12 x 1 body (Ø12 x 61 mm) designed for flush mounting in tight spaces. It detects ferrous targets with a 2 mm sensing range and delivers a single PNP normally open output via a 4-pin M12 connector, powered from 10–30 V DC. The IP67-rated enclosure protects it from dust and water in rugged industrial environments, including welding cells where magnetic-field resistance is essential. This model is the BES02J6 variant of Balluff’s BES 516-325-S4-W family and is commonly used for end-stop detection, position sensing on conveyors or feeders, and other compact metal-detection tasks that require reliable weld-immune performance in constrained installations. Its cylindrical, flush-mount design keeps cables and attachment points accessible in busy automation cells while delivering dependable, fast switching for metal-detection applications.
