Special Sensors

Leuze Logo

Under this heading are sensor solutions that must perform special detection tasks or which were developed for specific applications. Here you will find contrast and luminescence scanners as well as color sensors and systems for monitoring double sheets and splices as well as for overlap detection.

  • Contrast Scanners Contrast Scanners
    This sensor type can use various light sources – such as white light, laser-generated red light or RGB light – to very precisely detect and compare contrasts and report the results to the process with minimal signal jitter. Through the automatic selection of the right transmitter colors, various color or gray value combinations can be reliably detected.
  • Luminescence Scanners Luminescence Scanners
    This sensor detects both visible as well as invisible luminescent markings. It sends the result as switching output or analog value and is used primarily for sorting and inspection tasks in areas in which other detection methods fail to supply reliable results or where the markings should not or must not be visible.
  • Color Sensors Color Sensors
    This sensor type detects colors and compares them to a stored reference value. They are the right solution whenever the color of an object or marking can serve as a sorting or inspection criteria. Depending on the configuration and specified tolerance values of the system, the result is output as a switching signal.
  • Double Sheet and Splice Inspections Double Sheet and Splice Inspections
    Devices for ensuring system availability and the corresponding logistics in the graphics industry have been among our core competencies for decades. Not least of all because we have a great deal of practical experience and have application know-how from this business sector that has been collected over a decade.
  • Edge Detection in Overlap Flow Edge Detection in Overlap Flow
    The counting of products that are transported on conveyors and conveyor tracks in an overlapping arrangement – whether ultraflat or thin – is usually performed by means of a so-called layer counter.
