Sick UM18-20014 Overview



Ultrasonic sensor double sheet detection UM18-20014 Sender / Receiver 2 switching outputs NPN

Sick UM18-20014 Description



  • Double-sheet detection of foils, metal sheets and thin corrugated cardboard
  • Operational area 40 mm +/- 3 mm
  • Automatic adjustment, plug and play operation
  • Color- independent detection
  • Two PNP outputs for double and miss-fed sheets
  • Your benefits

  • Increased quality and productivity through reliable double sheet detection
  • Fast commissioning since sensor does not require calibration or teaching
  • Reliable detection of transparent foils, various paper types and thin metal sheets provide application flexibility
