The new SR22 series of 2 mm slot sensors has been developed as the most cost effective solution for label detection on reels. The infrared LED emission allows detection over even dark or thick supports, while the low response time of only 100μs allows to reach a 10 kHz switching frequency in the faster labeling processes.
The label detection sensitivity is trimmer adjustable. The compact metal housing with 40 mm slot depth fits even the most limited spaces. The M8 4-pole connector offers simple and fast connection. The power supply is 24 VDC and versions with light or dark mode, both with double NPN and PNP outputs, are available.
