Ultrasonic detection
SICK’s UM30 and UM18 ultrasonic sensors detect objects and measure distances with high accuracy.


Further advantages:
  • the outstanding background suppression and the reliable detection of objects almost independently of their appearance.
  • the application determines the output – binary or analog – according to your needs
The functional principles:
Ultrasonic proximity switch

  • One or two binary switching outputs, or analog output
  • Ultrasonic, non-contact detection and distance measurement of objects
  • Highly accurate measurements
  • Large scanning ranges
  • Detection of transparent objects and fluids
  • Highly available,even under unfavorable environments
  • Binary of analog output
Ultrasonic double-sheet detection
  • Double-sheet check for film, paper, corrugated cardboard and fine metal sheet
  • Automatic adjustment
  • Alignment and teach-in unnecessary
  • Compact design
  • Plug and play
  • 2 PNP outputs for double- and mis-fed sheets
