Balluff BES 516-326-SA96-S4-W Inductive Sensor

Balluff BES02JF, part of the BES 516-326-SA96-S4-W family, is a shielded inductive proximity sensor in a rugged M18 barrel designed for flush mounting. Measuring Ø18 x 65 mm with an M18x1 thread, it detects ferrous targets at a nominal distance Sn of 5 mm, with an assured operating distance Sa of 0–4 mm, and delivers a 3-wire PNP normally-open output. It operates on a DC supply of 10–30 V and draws up to 200 mA, with built-in short-circuit protection and reverse-polarity tolerance typical of Balluff devices. The housing is CuZn with PTFE coating and a sensing face made of LCP with PTFE, providing IP67 protection for durability in industrial environments. The S4 connector denotes a 4-pin M12 interface for reliable wiring, and this variant is marketed as magnetic-field-resistant to maintain performance in environments with stray magnetic fields. Common applications include inline metal sensing on conveyors, clamps, and automated assemblies where a compact, flush-mounted sensor is required in challenging surroundings, making it a direct fit for metal-detection tasks where space is limited and robustness is essential. The BES 516-326-SA96-S4-W configuration offers a proven 5 mm sensing distance, sturdy 65 mm housing, and a 10–30 V DC supply range, aligning with standard industrial control schematics for DC-proximity sensing in automation systems.
