SICK: AS30 Array Sensors
SICK has come out with the AS30 sensor arrays. 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.
