Mounting

The DCR 40 scan engine can be attached at two M2.5 through-hole mounting tabs.
Optionally, the DCR 40 scan engine is available without mounting tabs.
In addition, two 2 mm deep inserts for M1.8 self-tapping screws are provided on top of the scan engine.

Selecting a mounting location

NOTICE
The size of the code module influences the maximum reading distance and the width of the
reading field. Therefore, when selecting a mounting location and/or the code label, take into ac-
count the different reading characteristics of the scanner with various code modules.
NOTICE
Observe when choosing the mounting location!
Ä Maintaining the required environmental conditions (temperature, humidity).
Ä Possible soiling of the reading window due to liquids, abrasion by boxes, or packaging mate-
rial residues.
Ä Lowest possible chance of damage to the scanner by mechanical collision or jammed parts.
Ä Possible extraneous light influence (no direct sunlight).
The best read results are obtained when
• the reading distance lies in the middle area of the reading field.
• there is no direct sunlight and extraneous light is avoided.
• the bar code labels are of good print quality and have good contrast ratios.
• you do not use high-gloss labels.
• the bar code or the Data Matrix code is moved past the reading window with an angle of rotation of 10°
to 15°.
• the red light beam is narrowed down for its respective reading task in order to avoid reflections on shiny
components.
NOTICE
The front beam exit of the device is almost vertical to the optics. The code label must be rotated
by > 10° to avoid a total reflection of the red light beam in the case of glossy labels.
