Read Head Orientation
5.6.1
Horizontal Tolerance—Read Distance z
The read head offers the highest possible depth of field for cornering horizontal curves and
mounting at different reading distances. If the read head is mounted too close or too far away
on the Data Matrix code tape, a warning message is issued. We recommend that the read head
always be mounted at a nominal distance of 100 mm to ensure the highest possible availability
of the system (due to resolution and code redundancy). Pay particular attention to the reduced
mounting tolerance in the y direction and the reduced gap width, especially at extremely close
reading distances.
