Balluff BES 516-371-E0-C-05 Inductive Proximity Sensor

Balluff BES 516-371-E0-C-05 is a compact flush-mount inductive proximity sensor with a Ø6.5 x 45 mm form factor and a stainless steel housing. It operates on 10–30 V DC and provides a PNP normally-open (NO) switching output, ideal for detecting metal targets in tight spaces. The sensing range is 1.5 mm, and the device ships with a 5 m PUR cable for flexible installation. Designed for harsh environments, it features IP68 protection and an operating temperature range from -40 to 85 °C; the housing is stainless steel and the active sensing face is made of PBT. The sensor supports up to 5000 Hz switching frequency, making it suitable for high-speed automation applications. Although listed as BES 516-371-E0-C-05, catalog pages also reference BES 516-371-EO-C-PU-05, indicating the same hardware across variant naming; the BES01KE designation appears in related product listings. Common uses include precise position sensing on conveyors, robotic end-effectors, and inline presence checks where a small, flush-mounted metal-sensing solution is required.
