Balluff BES 516-384-E4-C Inductive Proximity Switch

The Balluff BES 516-384-E4-C inductive proximity switch is a compact, 8 mm‑dia stainless steel sensor in an M8x1 housing, 30 mm long, designed for DC operation from 10 to 30 V and a maximum current of 200 mA. This three‑wire device provides a NPN normally‑open output and a nominal sensing distance Sn of 2.5 mm, with an assured operating distance Sa of 0–2.0 mm for repeatable detection of metallic targets in steel environments. It is unshielded and intended for mounting in steel, with a PA12 sensing face and IP68 protection for demanding industrial conditions. Electrical specifications include a supply range of 10–30 VDC (24 VDC nominal), ripple up to 15%, and a maximum switching frequency of 2 kHz. The sensor offers short‑circuit and reverse‑polarity protection and is rated for DC 13 utilization; it uses a LiYY‑O cable. Mechanical robustness includes shock resistance to 30 g (half‑sine) and vibration tolerance of 55 Hz with 1 mm amplitude (3 × 30 min). A time delay before availability is about 20 ms. Operating temperature ranges from −25 to +70 °C, and the housing is designed for a rugged industrial environment with IP68 protection. With its stainless‑steel body, 2.5 mm sensing range, and metal‑sensing capability, the BES 516-384-E4-C is well suited for industrial position sensing, automation tasks, and applications requiring reliable metal detection in harsh environments.
