Balluff BES-516-210-S21-E Inductive Proximity Sensor

Balluff BES-516-210-S21-E is a compact inductive proximity sensor (BES028J) designed for metal-detection tasks in automation. Measuring Ø12 x 70 mm, it features a stainless-steel housing (M12x1), non-flush installation, a PA12 sensing surface, and a 4 mm sensing range, paired with a normally closed (NC) switching output. It accepts a wide supply of 20–250 V AC or DC and terminates with a 1/2"-20 UNF-2A male connector, enabling straightforward field wiring, while delivering a switching frequency up to 600 Hz and an IP67 rating for use in harsh environments from -25 to 70 C. The BES-516-210-S21-E is cataloged under the BES028J order code and is part of Balluff’s BES 516 family of rugged inductive sensors, designed for reliable metal sensing in industrial applications.
