Balluff BES-516-200-S2-1.250-S5 Proximity Switch

Balluff BES-516-200-S2/1.250"-S5 is a flush‑mount, pressure‑rated inductive proximity switch (normally open) from the BES 516 family, designed for demanding industrial environments. It features a 2 mm sensing distance, a stainless steel housing with a ceramic active face, and a 10–30 V DC operating supply, suitable for -25 to 70 °C operation with IP67 protection and magnetic‑field immunity for AC/DC. The sensor is rated to withstand up to 207 bar of external pressure and can be configured with M12x1 4‑pin or 7/8‑16 UN connectors depending on the variant, with overall dimensions of 51 × 48 × 31.75 mm (Bauform D12.7). Certifications include CE, cULus, and EAC, making it a compact, durable choice for high‑pressure, flush‑mount sensing in automation and machine tooling.
