Balluff BES 516-356-E4-C-PU-05 Inductive Sensor

Balluff BES 516-356-E4-C-PU-05 Inductive Sensor is a compact M12 cylindrical proximity switch intended for metal-detection tasks in automated equipment. It has a 4 mm sensing distance (sn=4) and an overall body length of 38 mm, with a 5 m fixed cable (PU-05) for flexible installation away from the control cabinet. The sensor operates on 10–30 V DC and delivers a PNP normally open output, making it compatible with standard logic inputs used in modern machine controls. The M12 housing size and inductive sensing principle suit metal targets, enabling reliable end-of-travel, position sensing, and presence indication on conveyors, robotic cell fixtures, and tooling setups. As part of Balluff’s BES family, this device is designed for straightforward wiring in 10–30 VDC control circuits and provides stable metal-target detection without physical contact. With a 5-meter lead, it supports installations where the sensor must be positioned away from the controller, and its 38 mm length keeps the profile compact for tight spaces. Typical applications include automated assembly lines, packaging machinery, CNC machines, and other metal-friendly environments where a contactless sensing signal is required for sequencing, safety interlocks, or feedback loops.
