Balluff BES516-208-S21-E Inductive Proximity Sensor

The Balluff BES0282 BES 516-208-S21-E is a stainless-steel, cylindrical inductive proximity sensor with a 12 mm diameter and 70 mm length designed for flush mounting in industrial equipment. Its PA12 sensing face detects metallic targets at a 2 mm range and provides a normally closed (NC) switching output. The device accepts a universal 20–250 V DC or AC supply and uses a 2-wire connection via a 1/2"-20 UNF-2A-Male connector, simplifying integration into control circuits. Built for harsh environments, it carries IP67 protection and operates across -25 to 70 °C, making it suitable for dusty, moist, and temperature-variant settings. With an M12x1 housing and compact form factor, it fits tight spaces while delivering reliable switching at up to 1 kHz.
