Balluff BES-517-139-P5-H Inductive Proximity Sensor

Balluff BES-517-139-P5-H is an inductive proximity sensor designed for non-contact detection of metal targets in industrial automation. It delivers a 50 mm sensing distance (Sn = 50 mm) for reliable presence sensing in mid-range applications such as conveyors, machining lines, and robotic cells. The device operates from a DC supply of 10 to 55 V and draws up to 200 mA, enabling straightforward integration with standard PLC inputs and controllers. This model is part of Balluff’s BES 517-139 family and is configured for rugged, practical mounting in demanding production environments. The P5-H variant represents one of the housing options Balluff offers within this family, tailored for installations where metal target detection needs to be achieved quickly and reproducibly. In typical automation use cases, such sensors provide fast response in end-of-travel sensing, position feedback, and presence detection tasks where contactless metal sensing improves reliability and reduces wear. When selecting this sensor, engineers benefit from a proven 50 mm sensing range and a DC power-compatible design that fits into common control schemes used across manufacturing lines.
