Balluff BES M30EG1-PSC20Z-S04G-S11 Inductive Sensor

The Balluff BES M30EG1-PSC20Z-S04G-S11 is a 30 mm-diameter inductive sensor (M30 housing) that detects metal targets without contact and is designed for flush mounting in steel environments. It operates from 10 to 30 V DC and draws up to 200 mA in a 3-wire configuration, delivering a PNP normally-open output via a 4-pin M12 connector, with a stainless steel body (M30x1.5, 63.5 mm long) and sensing face of 1.4305 stainless steel. The nominal sensing distance Sn is 20 mm, with an assured operating distance Sa of 0…16 mm, and the device is described as quasi-shielded with IP67 protection; mounting in metal can reduce the switching distance, while the unit withstands ambient temperatures from -25 to +70 °C. Key electrical features include LED indication, short-circuit and reverse polarity protection, a maximum switching frequency of 100 Hz, ripple up to 15%, and a rated operating current of 200 mA; the sensor is rated for pressure resistance in the P area up to 40 bar.
