SR31-0
The SR31-0 is a compact metal-housing (Zamak) fork/slot photoelectric sensor from Datasensing (Datalogic) featuring infrared LED emission and a 30 mm wide, 42 mm deep sensing slot. It achieves a high switching frequency of 10 kHz (response time 50 µs), making it well suited for fast-moving label or web detection tasks. The NPN open-collector output is light/dark selectable via internal trimmer, and the unit operates on 10–30 VDC with an M8 4-pin connector. Protection is IP60; housing is metal Zamak with a glass active head.
