Sensor for counting number of rotations
Holes in rotating disk detected for measuring number of rotations or speed (RPM).
Positioning of rolled paper
Rolled paper positioned on printer. Sensor with focused laser beam ensures high accuracy.
Detection of lifting of ejected paper
Background suppression photo sensor is unaffected by color variation and therefore used for detecting any lifting of ejected paper.
Detection of tapes on paper joint lines
Tapes applied on paper joint lines are detected. Only variations in the level of light received are used to determine gradual changes in light level.
Film loop control
Winding speed controlled by output in proportion to size of loop.
Lettuce detection
Background suppression sensor less influenced by color or gloss of object
Detection of roll thickness (distance)
Thickness of material wound on roll or distance stably detected without being affected by paper dust or dirt.
Steamed fish paste detection
Background suppression sensor less influenced by color or gloss of object
Detection of broken paper on rotary press
Limited-distance sensor not affected by print colors.
