Mounting and installation
Leuze electronic GmbH + Co. KG
BPS 8
36
In order to select the right mounting location, several factors must be considered:
• The working range must be adhered to at all areas at which a position determination is to be made.
• The BPS should be mounted at an angle of 10° (depending on the tape height, see note on see
page 36) in the horizontal axis relative to the bar code tape to ensure continued reliable positioning
results even in the event of soiling of the bar code tape.
• On the BPS 8, the beam is not emitted perpendicular to the cover of the housing, but with an angle of
about 4°±2° towards the bottom. To achieve a total pitch greater than/equal to 10°, the mounting
bracket BT 8
-
01 has an angle of about 8°±0.5°. This angle must not fall below this value. A total
reflection of the scanning beam on the bar code tape is thus prevented. With the angles integrated
into the BT 8
-
01, the BPS 8 can be mounted in parallel to the bar code tape in the reading distance
required.

NOTE
Angle of inclination!
For the mounting, an angle of inclination of
• 10° for a tape height of 47mm,
• 5° for a tape height of 30mm or 25mm
must be factored in the vertical axis and the working range of the reading field curve.
