MOUNTING AND POSITIONING MATRIX 320
PRODUCT REFERENCE GUIDE
67
Matrix 320 is able to decode code labels at a variety of angles; however significant
angular distortion may degrade reading performance.
When mounting Matrix 320, take into consideration these ideal label position angles:
Pitch or Skew 10° to 20° and Tilt 0°.
The Pitch, Skew and Tilt angles are represented in Figure 48. 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 320 reader; it is advised to assure at least 10° for the Skew angle.
Figure 48 - Pitch, Tilt, and Skew 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 also represented in Figure 48. Matrix 320 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
Chapter 6, Reading Features for FOV vs. Reading Distance considerations.
NOTE
Since Matrix 320 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.
