Optical short-range distance sensors

In addition to its analogue voltage output, the FT 20 R(L)A also has a switching output and offers the possibility of defining a switching window by means of two switching points. It can thus serve as a threshold switch. Thanks to their simple operation, these sensors are suitable for straightforward measurement and control tasks at distances of up to 200 mm.

  In a miniature housing The FT 20 R(L)A is also suitable for limited installation spaces thanks to its compact dimensions of 32 x 12 x 20 mm.

  Key applications:

  • Dancer roll regulation and sag monitoring
  • Determining the roll diameter of an unwinding machine
  • Stacking height measurement, double layer detection and height measurements in the wood processing, packagingand handling industry
  • Distance measurement and positioning on robot grippers at „pick & place" applications

   

  FT 25-RA for dancer roll regulation: The precise control of the FT 25-RA ensures a constant tension of the paper roll during unwinding.
