Basic Features
The BES M12MI-PSC40B-S04G inductive sensor is compliant with CE, UKCA, cULus, and WEEE standards, and follows the IEC 60947-5-2 basic standard. It features a function indicator but lacks a power indicator.

Electrical Connection
The sensor uses an M12x1-Male, 3-pin, A-coded connection. It is protected against polarity reversal, device mix-ups, and short circuits.

Environmental Conditions
The sensor operates in ambient temperatures from -25 to 70 °C, with a contamination scale of 3. It is shock-resistant (EN 60068-2-27) and vibration-resistant (EN 60068-2-6), with an IP68 rating.

Functional Safety
The Mean Time to Failure (MTTF) at 40 °C is 640 years. The switching output is PNP normally open (NO).

Material
The housing is made of brass with a nickel-free coating, and the sensing surface is made of PBT.
