Double sheet monitoring

Product selector

One at a time

The double sheet monitoring devices from Leuze electronic reliably prevent multi-layer sheets from being drawn in. As a result, scrap and damage are reliably avoided with machines that process stacks of paper and cardboard.
The systems operate on the basis of various physical principles and are thus able to cover nearly the entire range of applications.

They have it covered

Multi-layer paper and plastic sheets as well as metal foils are reliably detected by an M18 ultrasonic sensor.

  • Double sheet detection of paper, plastic and metal foils
  • Measurement range 20 g/m² to 1,200 g/m² (homogeneous cardboard)
  • Ultrasonic sensors in M18 cylindrical sensor housing
  • Ultrasound models in 25 mm or 42 mm housing lengths
  • Indicator diodes for alignment and diagnostics
  • Teach button

These help when space is tight

Particularly in constrained spaces, such as in post-press processing, an M12 ultrasonic sensor reliably detects multi-layer paper and plastic sheets as well as metal foils.

  • Double sheet detection of paper, plastic and metal foils
  • Measurement range 20 g/m² to 800 g/m² (homogeneous cardboard)
  • Ultrasonic sensors in M12 cylindrical sensor housing, 20 mm housing length
  • Very small sensor construction
  • Indicator diodes for alignment and diagnostics
  • Teach button

Reliability, black on white

This series reveals its strengths in the double sheet monitoring of paper and cardboard. Even printing and fluttering paper are no problem. It works though a combination of ultrasonic and capacitive sensors.

  • Double sheet detection of paper, cardboard, plastic and metal foils
  • Measurement range 20 g/m² to 2 mm thick cardboard
  • Ultrasonic sensors in M18 cylindrical sensor housing
  • Ultrasound models in 25 mm or 42 mm housing lengths
  • Thin capacitive sensor
  • Automatic readjustment during operation
  • Extensive diagnostic options via 2-digit 7 segment display
