Positioning tray stacks

The tray stacks must be precisely positioned on the belt conveyor to allow a gripping arm to supply or remove trays. This task is handled by the CQ4 capacitive proximity sensor. With its small sensing range and compact form, the sensor can be integrated in the direct vicinity of the process, even where little space is available. The capacitative sensor technology enables a material-independent and safe detection of trays, no matter what object properties they have.
