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.

Automation light grids

Two-dimensional inspection or counting tasks are important in automation. SICK’s automation light grids can be used in a number of these solutions, such as detecting and counting irregularly shaped objects, people and vehicles, and checking for presence and pallet overhang detection. The tasks are so versatile that one light grid cannot fulfill the requirements of every application. Light grids from SICK offer multiple ranges, heights, sizes, orientations, and resolutions which simplify integration through high flexibility and performance.

Capacitive proximity sensors

Liquids, granulates, glass, powder, wood and more – capacitive sensors detect almost any object by non-contact means, regardless of color, reflection factor, and surface characteristics. After suitable adjustment of the sensitivity, they even detect objects behind non-metallic walls and can therefore provide a cost effective alternative for level measurement.

Color sensors

Color sensors detect object colors. To do so, the sensors emit light throughout the entire visible range onto the objects to be inspected, calculate the color proportions from the reflected light and compare these with previously taught reference color values.

Condition Monitoring sensors

The Condition Monitoring sensors from SICK allow intelligent condition-based monitoring. They determine relevant physical parameters for mission-critical processes and applications. The sensor data provide the foundation for analyses that make condition-dependent maintenance possible. Besides reducing unplanned downtimes, they can thereby also increase the service life of components and reduce costs.

Contrast sensors

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.
