Balluff BES 516-324-E0-C-PU Inductive Proximity Sensor

Balluff BES 516-324-E0-C-PU is a flush‑mount inductive proximity sensor housed in a durable stainless steel cylinder (Ø 8 x 45 mm) with a PUR jacketed connection and a PBT sensing face designed for metal targets. The sensor delivers a nominal sensing distance (Sn) of 1.5 mm with an assured operating distance (Sa) of 1.2 mm and a real switching distance (sr) of 1.5 mm, with hysteresis capped at 15% of Sr and temperature drift up to 10%, making it predictable in compact automation layouts. Its robust format supports flush mounting via the M8x1 thread and a tightening torque of 8 Nm, which helps maintain position accuracy in vibration‑prone environments. The BES 516 family uses a PUR jacket and stainless steel housing to withstand industrial conditions, while the sensing surface is made from PBT for reliable contact against metal surfaces. Typical variants in this line are provided with a fixed PUR cable length, and the 516‑324 models commonly appear with a 3 m lead length on the documented configurations, aligning with Balluff’s standard 8 mm sensing face and compact dimensions for narrow installation footprints. Power is drawn from a DC supply in the 10–30 V range, with a maximum current draw around 200 mA, making it suitable for direct integration with common PLC I/O rails and compact control circuits without requiring an external regulator. This sensor is well suited for applications such as position sensing, end‑of‑travel detection, and presence verification on conveyors, automated assembly cells, and machine guards where a small, rugged inductive switch is needed.
