Matrix 400™ is able to decode code labels at a variety of angles, however significant angular
distortion may degrade reading performance.
When mounting Matrix 400™, take into consideration these ideal label position angles: Pitch
or Skew 10° to 20° and Tilt 0°.
Note: Since Matrix 400™ 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.
Follow the suggestions below for the best orientation:
The Pitch and Skew angles are represented by the values P and S in Figure 46 and in Figure
47. Position the reader in order to avoid the direct reflection of the light emitted by the Matrix
400™ 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°.

The Tilt angle is represented by the value T in Figure 48. Matrix 400™ can read labels with
any tilt angle.
