Industrial BES-516-300-S-166-PU-3 Proximity Switch

Balluff BES 516-300-S166-PU-3 is a compact inductive proximity switch that detects ferrous metal without contact at a 1.5 mm sensing distance, enabling reliable metal presence sensing in tight spaces. It arrives with a pre-wired PUR cable (30 cm) terminated by a 4-pin M12 A-coded connector for quick, plug-and-play installation in automation equipment. The sensor operates on 10–30 V DC and provides a single PNP normally‑open output rated up to 200 mA, making it suitable for direct interfacing with standard industrial controllers. Its rugged construction features a die-cast zinc housing with a PUR jacketed cable and a PBT sensing surface, and it carries an IP67 rating for dust and water ingress protection, with an ambient temperature range up to approximately +70°C. In practice, this model supports high switching frequencies (up to about 5 kHz) and is commonly used for position sensing on conveyors, tooling, and other machine‑level applications where robust, non-contact metal detection is required. The BES-516-300-S166-PU-3 variant aligns with Balluff’s BES 516 family, delivering dependable performance in demanding industrial environments while maintaining straightforward integration through its M12 connection and standardized 10–30 V DC supply.
