Matrix 210™ is able to decode code labels at a variety of angles, however significant angular
distortion may degrade reading performance.
When mounting Matrix 210™, take into consideration these
ideal label position angles: Pitch
or Skew 10° to 20° and Tilt 0° .
Note:
Since Matrix 210™ 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 Pitch angle.
Follow the suggestions below for the best orientation:
The
Pitch and Skew angles are represented by the values P and S in Figure 34 and in Figure
35. Position the reader in order to avoid the direct reflection of the light emitted by the Matrix
210™ reader; it is advised to
assure at least 10° for one of these angles. In some cases, such
as low contrast or low illumination, it can be useful to use a Pitch or Skew angle = 0°.
P
Assure at least 10°

The
Tilt angle is represented by the value T in Figure 36. Matrix
210™ can read labels with
any tilt angle.
