Operating principle of the reading system
The camera system is an intelligent sensor system for the automatic and non-contact
identification and decoding of 1D/2D codes. In principle, the codes can be identified on
any side of moving objects in a conveyor system.
In the case of single-side reading, the codes are identified by a camera from above,
below, or from the side. To facilitate the mounting and alignment of the camera system,
the camera image is taken via a deflector mirror.
The camera system is operated in conjunction with a controller unit, by means of which
the read results are output to the data interfaces.
