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

The Balluff BES00UR inductive proximity sensor (516-356-E4-C-PU-05) is a compact, over‑surface sensing device designed for metal detection with a 4 mm nominal range. Encased in a 12 mm diameter M12x1 housing, the sensor measures 38 mm long with a mounting length of 29.5 mm and a depth of 37.5 mm, and uses a copper-zinc housing with a PBT sensing face for durability in demanding environments. It switches via a PNP normally‑open output and comes with a 3‑conductor PUR cable, 5.00 m long (Ø 4.60 mm jacket) for straightforward installation. The device operates on DC supply from 10 to 30 V (UB) and draws up to 200 mA, with a no‑load current around 4–10 mA depending on load conditions. Electrical protections include polarity reversal protection and short-circuit protection, and the sensor provides a functional indication feature. The enclosure is IP68 rated, and it withstands ambient temperatures from -25 °C to +70 °C, making it suitable for industrial environments. Sensing performance is Sn = 4.00 mm with an assured operating distance Sa of 3.20 mm and a maximum switching distance Sr of 4.00 mm. Certifications include CE, cULus, and EAC, reflecting compliance with IEC 60947-5-2. Balluff lists an MTTF of 830 a at 40 °C, underscoring reliability for continuous operation. This BES00UR device is ideal for automation tasks on conveyors, tooling, and robotic assemblies where a rugged, easy-to-wire inductive sensor in a compact form factor is required.
