Summary

SR31 Series

The SR31 series is composed of fork sensors with infrared LED emission, distinguished by an elevated 10kHz switching frequency and by a sturdy and compact metal housing.

The detection sensitivity is adjusted by means of a trimmer. The dark/Iight operating mode is configured according to the connection. The series includes M8 connector versions with NPN output, or PNP output; cable versions present both NPN/PNP outputs.

The SR31 sensors have e 30 mm wide and 42 mm deep fork These sensors are suitable for detecting opaque Iabels on a transparent support, to control material presence and continuity, to detect synchronism pulses on toothed or holed wheels, or as on-off edge guide.
