Balluff BES 516-324-E4-C-PU-05 Proximity Sensor

The Balluff BES 516-324-E4-C-PU-05 is a cylindrical inductive proximity sensor (M8, 8 mm diameter) designed for flush‑mount installation and metal‑detection tasks on industrial equipment. It measures Ø8 × 30 mm with an M8x1 thread and provides a three‑wire PNP normally‑open output, powered from 10–30 V DC and drawing up to 200 mA. The sensing face is PA12, the jacket is PUR, and the housing is stainless steel, delivering rugged performance in harsh environments. For field wiring, it ships with a 5 m PUR cable (PU‑05). The device carries IP68 protection, suitable for immersion and washdown in demanding applications. Balluff specifies a rated operating distance Sn of 1.5 mm, an assured distance Sa from 0 to 1.2 mm, and a real switching distance sr of 1.5 mm, with a hysteresis of about 15% and a repeatability around 5%. It is a 3‑wire DC sensor with PNP NO output, and the -PU-05 suffix denotes the 5 m cable length. Common applications include end‑of‑line or presence sensing on conveyors, automated fixtures, and machine tools where a compact, robust inductive sensor is required.
