Balluff BES 516-325-E4-Y Proximity Sensor

The Balluff BES 516-325-E4-Y proximity sensor is a compact flush-mount inductive switch in a Ø12 x 33 mm M12 housing that detects metal targets within a 2 mm sensing range. It operates from a 10 to 30 V DC supply and provides a PNP normally open (NO) switching output, suitable for directly pulling in loads or interfacing with control logic. The sensor switches at up to 3,500 Hz and uses a brass, nickel-free coated housing with a PBT sensing surface for durable, corrosion-resistant performance. Cable options are commonly 5 m, with variants offered in PVC or TPU jackets; it carries IP68 protection for robust operation in dusty or wet environments across a wide operating temperature of -25 to 70 °C. Designed for flush-mount installation, its compact Ø12 x 33 mm form factor minimizes protrusion on machine surfaces while maintaining reliable metal-target detection, making it suitable for integration with PLCs and other control electronics in automation and packaging equipment.
