Balluff BES M18ML-PSC50A-S04G-W proximity switch is a compact, flush‑mount inductive sensor in an M18 housing (Ø18 x 65 mm) with a 5 mm sensing distance, optimized for metal detection in harsh industrial settings. Operating on 10–30 V DC (typical 24 V) with a 3‑wire PNP normally‑open output, it can switch up to 200 mA at frequencies up to 2.5 kHz. Its construction uses CuZn housing with PTFE coating and a sensing face of LCP with PTFE, and the electronics are sealed to IP67 for protection against dust and water. Configured for flush mounting with an M12 x 4-pin connector (S4), it's a Factor 1, weld‑immune sensor suitable for repeated metal detection in automation lines.
