Balluff BES-516-19-12-85 Inductive Proximity Switch

Balluff BES-516-19-12-85 is a cylindrical inductive proximity switch designed for non-contact detection of metal targets in industrial automation. This 3-wire device operates from 10 to 30 V DC and delivers a PNP normally closed (NC) output for straightforward wiring into control circuits. The sensor is housed in stainless steel with a PA12 sensing surface and measures Ø12 x 70 mm, suitable for non-flush mounting. It uses an M12x1 four-pin connector for field wiring, providing robust connectivity in harsh environments. The active sensing distance is 4 mm, enabling reliable detection of small metal parts without physical contact. Built to endure tough conditions, the unit carries an IP68 ingress protection rating and an extended operating temperature range of -40 to 85 °C. Balluff’s BES 516 family is designed for demanding automation tasks such as position sensing and integration into conveyors, robotic grippers, and other automated equipment where durable metal sensing is required. This model's stainless-steel body and PA12 sensing surface balance mechanical robustness with responsive sensing for metal objects across a wide range of industrial applications.
