Balluff BES-516-371-E4-C-PU Inductive Proximity Sensor

Balluff BES-516-371-E4-C-PU is a flush‑mount inductive proximity sensor (Ø6.5 x 30 mm) with a stainless‑steel housing and a 28.7 mm mounting length, designed to detect metal targets at close range. It switches with a PNP normally open output and operates from 10 to 30 V DC, delivered over a 3‑conductor PUR jacketed cable that is 3.0 m long. Sensing performance lists a nominal distance (Sn) of 1.50 mm, an assured operating distance (Sa) of 1.20 mm, and a real distance (Sr) of 1.50 mm, with a sensing face of PBT and a cable diameter of about 3.1 mm. The device is IP68 rated for robust protection in demanding environments and supports flush installation at temperatures from -25 to 70 °C. This variant, BES00Z6, corresponds to the BES 516‑371‑E4‑C‑PU family and is commonly used in automation for conveyors, packaging lines, and robotic assemblies where a compact, shielded inductive sensor is required. The model is typically supplied with a 3.0 m PUR cable and a 6.5 mm sensing face, making it suitable for tight spaces while delivering reliable metal detection in industrial settings.
