Matrix 210N is able to decode code labels at a variety of angles, however significant angular
distortion may degrade reading performance.
When mounting Matrix 210N, take into consideration these
ideal label position angles: Pitch
or Skew 10° to 20° and Tilt 0° .
Note: Since Matrix 210N is omni-directional on the code plane, the Pitch and Skew angles
have the same significance with respect to the code plane. However in some advanced code
reading applications performance can be improved by modifying the Skew angle.
The
Pitch, Skew and Tilt angles are represented in Figure 40. Follow the suggestions below
for the best orientation:
Position the reader in order to avoid the direct reflection of the light emitted by the Matrix 210N
reader; it is advised to
assure at least 10° for the Skew angle.

In some cases, such as low contrast or low illumination, it can be useful to use a
Pitch or
Skew angle = 0°.
Matrix 210N can read labels with any tilt angle. Keep in mind however, that since linear
barcodes are rectangular, the reader should be aligned to fit them into the horizontal FOV.
See chp. 6 for FOV and Reading Distance considerations.
