Datasheets

Ultrasonic sensors for double material detection protect against faulty material feed and ensure reliable processes and high plant availability: double sheet control on printing and paper machines and in sheet metal and panel processing; splice detection on paper, sheet metal or textile rolls; detection and counting of labels in labelling systems. They work on the thru-beam principle; the ULB/UGB versions are insensitive to printing, colours and shiny surfaces.

Key features

  • UDC-18GS/30GS: double sheet detection from thin paper to thick cardboard with a single configuration, IO-Link, teach-in and automatic synchronisation
  • UDCM-30GS: for thick materials such as metal sheets up to 3.5 mm, parquet, wooden boards and OSB, 30 ms response time
  • ULB-18GM50 (labels) and UGB-18GM50 (splices): compact housing, ideal for transparent materials
  • IO-Link/push-pull outputs (UDC/UDCM) or 2 × NPN / 2 × PNP (ULB/UGB)
  • 18…30 V DC supply, cable with M12 connector or fixed cable
