SR31-1
The SR31-1 is a photoelectric slot (fork) sensor in the SR31 series with a 30 x 42 mm fork gap, infrared LED emission, and PNP transistor output with selectable light-on/dark-on operation. It operates from 10–30 V DC, achieves a 10 kHz switching frequency with 50 µs response time, and is housed in a compact metal (Zamak) body measuring 13 × 50 × 70 mm. The sensor connects via an M8 4-pin plug and is rated IP60, with an operating temperature range of −10 °C to +60 °C. Designed for detecting opaque labels on transparent carriers, small component presence, synchronism pulses on toothed wheels, an
