It is most suited for object detection on a large manufacturing line, or for detecting the falling or entrance of tiny items with an unpredictable journey route. It is ideal for detecting items of varying sizes and shapes at random points as this move through the target area. The presence of an item can be detected using proximity sensors and other sensor technologies.
