Registration sensors

Registration sensors

The variety of tasks in automated production processes today, such as in packaging and printing machines, require sensors with the highest performance standards. Typical applications are the detection of visible and non-visible marks, labels and colours at high speeds as well as the detection of small parts and precise positioning. SICK offers a wide range of contrast, markless, colour, luminescence, fork and array sensors to solve this wide spectrum of demanding tasks.

Line-for-line further ahead – array sensors

Array sensors operate on the proximity scanning principle. They detect even the smallest edges based on differences in grayscale values within the field-of-view. Positioning of, for example, a paper web based on the web edge or a contrast line is only one of many possible applications. Widths, diameters, and gaps can also be detected. In reflector mode, the array sensors can even detect transparent materials.


From pattern detection to rapid position identification

The pattern sensor is a proximity-scanning opto-electronic sensor. Distinctive patterns in an image are used as a reference for the subsequent, accurate detection and positioning of objects. A stable switching signal is generated at high speeds with an intelligent algorithm for signal processing regardless of reference marks. It is typically used in the packaging industry.
