Balluff BES 516-3005-G-E4-C-S49-00,3 Inductive Proximity Sensor: Complete Technical Guide
On this page
What is the Balluff BES 516-3005-G-E4-C-S49-00,3?
The BES 516-3005-G-E4-C-S49-00,3 (catalogue family BES00HC) is a Balluff precision inductive proximity sensor on an M8 stainless thread: 1.5 mm rated sensing distance, 10...30 V DC supply at up to 100 mA, a PNP normally-open output, -25 to 70 °C operation, and a short 0.3 m lead ending in a 4-pin M12 connector. The bag print carries the full electrical set plus CE, EAC and cULus listing, and marks the country of origin as Hungary — Balluff's own European plant. The record covers 5 sensors, new in sealed Balluff bags. All 5 photos and 1 video below show these exact units.

Reading the long ordering code
Balluff's part numbers are a spec sheet in themselves, and this one decodes cleanly: BES 516 is the M8-thread precision family, 3005 the size step, G the stainless housing, E4 the electrical variant, C the connector output, S49 the active-face geometry, and 00,3 the 0.3-metre stub lead to the M12 plug. The short pigtail matters in tight machines — the sensor screws in with its lock nut and the M12 plug lands on a standard cordset, so panel wiring never has to reach into the machine. At 1.5 mm rated distance this is a precision position switch rather than a presence sensor: it picks up targets fractions of a millimetre apart, which is what tool-change confirmation, end-stop and reference-point duty in machine tools demand. Wiring is the standard M12 4-pin arrangement printed on the bag — pin 1 positive, pin 3 negative, pin 4 the PNP switching output. KOEED lists sibling sensors from the same family, such as the BES 516-3005-E4-C-PU-05, and other Balluff M8 switches like the BES M08EH-POC15B-S04G.
