MOUNTING AND POSITIONING MATRIX 220
PRODUCT REFERENCE GUIDE
61
Matrix 220 is able to decode code labels at a variety of angles; however significant
angular distortion may degrade reading performance.
When mounting Matrix 220, take into consideration these ideal label position angles:
Pitch or Skew 10° to 20° and Tilt 0°.
Note: Since Matrix 220 is omni-dir
ectional 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 angl
es are represented in Figure 37. 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 220 r
eader; 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°.
The Tilt angle i
s also
represented in Figure 38. Matrix 220 can read labels with any tilt
angle. Keep in mind however, that since linear barcodes are rectangular, the reader
should be ali
gned to fit them into the horizontal FOV.
