Balluff BES0058 BES M12MI-NSC40B-BV05 Inductive Sensor

Balluff BES0058, marketed as BES M12MI-NSC40B-BV05, is a compact M12 inductive proximity sensor with a 4 mm sensing distance designed for metal targets. It provides a NPN normally open output that operates from 10 to 30 V DC and can sink up to 200 mA through a 5 m PVC cable (three conductors, 0.34 mm²; cable diameter about 4.6 mm). With an overall body length near 53 mm, it fits neatly into tight spaces while offering IP68 protection for rugged industrial use and an ambient operating range of -25 to +70 °C. The sensor includes safety features such as polarity reversal protection, device-mix-up protection, and short-circuit protection, and supports a switching frequency up to about 2,500 Hz for fast detection on conveyors and automation lines. RoHS-compliant and backed by Balluff reliability data, it lists a mean time to failure (MTTF) of 555 a at 40 °C. This model is ideal when a ready-to-use, cable-connected inductive switch is needed in compact form factors, enabling reliable metal presence sensing in machines, guards, and automated stations with simplified wiring through a 5 m lead.
