Contrast sensors
SICK – The pioneer in contrast sensors for more than 60 years
Contrast sensors are primarily used in packaging/printing machines for the detection of printed or control marks. SICK's line of KT contrast sensors detects even the smallest contrasts at the highest speeds, such as print marks on foils or packaging. They detect minute grayscale variations between the mark and the background on matte, shiny or transparent surfaces. A variety of device types with different contrast resolution methods and teach-in versions are available to meet wide-ranging requirements.
