Balluff BES 516-208-S21-E Inductive Proximity Sensor

Balluff BES 516-208-S21-E (BES0282) is a cylindrical inductive proximity sensor designed for flush mounting in tight spaces, measuring Ø12 x 70 mm with an M12x1 housing and a 3‑pin connection for a compact, integrated fit in automated equipment. It detects metal targets within a 2 mm sensing range and switches with a normally closed (NC) output, making it suitable for end‑of‑travel, position sensing, and metal‑presence monitoring on conveyors, fixtures, and other machinery. The sensor supports a universal Ub of 20 to 250 V AC or DC, enabling easy integration into mixed power environments without special adapters. Built with a stainless steel housing for durability, it carries an IP67 ingress protection rating and operates reliably across a wide ambient temperature range from -25 °C to +70 °C, supporting use in harsh industrial surroundings. Typical applications span automated assembly lines, packaging equipment, and robotics where precise, metal‑target detection is required in a compact, flush‑mount footprint. This Balluff unit combines robust construction with straightforward installation and a 3‑pin M12 interface, delivering predictable switching for reliable automation feedback and control.
