Balluff BES 516-355-BO-C Inductive Proximity Sensor

Balluff BES 516-355-BO-C Inductive Proximity Sensor is a flush‑mounted M18 cylindrical sensor with a 5 mm nominal sensing distance (Sn), engineered to detect ferrous targets without contact in compact spaces. It delivers a three‑conductor NPN normally‑open output powered from 10 to 30 V DC, and it comes with a 5 m LiYY‑O cable on a PVC jacket for easy deployment in machinery and panels. The housing is nickel‑plated brass with a PA12 sensing face, compatible with flush installation in steel housings, and the body measures Ø18 mm with a length around 76.5 mm. Electrical performance includes a maximum switching frequency of 500 Hz, a rated operating current up to 200 mA, and a static voltage drop near 2.5 V, with built‑in short‑circuit and reverse‑polarity protection. The device is IP68 protected and rated for ambient temperatures from –25 to +70 °C, offering an assured operating distance Sa of 0–4.0 mm and a nominal sensing distance Sr of 5.0 mm for reliable detection across target tolerances and material variations.
