Selecting a mounting location
In order to select the right mounting location, several factors must be considered:
• The scanning range determined from the scanning curve must be adhered to at all
locations where a position determination is to be made
• The BPS should be mounted at an angle of 10° (depending on the tape height, see
notice page 39) in the vertical axis relative to the barcode tape to ensure continued
reliable positioning results even in the event of soiling of the barcode tape.
• On the BPS 34, the beam is not emitted perpendicular to the cover of the housing, but
with an angle of 10 ° towards the top. This angle is intended to prevent total reflection
on the barcode tape. This beam exit is already integrated in the device. As a result,
the BPS can be at the minimum read distance and mounted parallel to the barcode
tape.
