Balluff BES M18ML-PSH12E-S04G-W Inductive Sensor

Balluff BES M18ML-PSH12E-S04G-W is a compact inductive proximity sensor in an M18 housing (Ø18 x 65 mm) with a 12 mm nominal sensing distance for metal targets, designed for non‑flush installation. It uses a 3‑wire DC interface with a PNP normally open output and operates from 10 to 30 V DC (typical 24 V), switching up to 200 mA at load and delivering a maximum switching frequency of 2,500 Hz; an LED indicator accompanies the output to confirm switching status. The device is built with a CuZn housing that’s PTFE coated and a sensing face of LCP + PTFE, rated IP67 for protection against dust and immersion, and specified for an operating range of -25 to +70 °C with weld‑immune construction and magnetic‑field tolerance up to 100 kA/m. Electrical protections include reverse‑polarity protection and short‑circuit protection, with no‑load current up to about 15 mA (typical around 10 mA), a voltage drop near 2 V, and ripple up to 10%; the wiring uses a 4‑pin M12 connector (S4).
