Datalogic Scanning DS4600A User Manual

DS4600A 

 
The most important parameter in Advanced Code Reconstruction is the value of the 
maximum tilt angle (

α maximum) under which the code reconstruction process is still 

possible. 
 
We define the Tilt angle as the angle (

α) between the laser beam and a line parallel 

to the barcode label, as shown in Figure 29.

The formulas to calculate 

α maximum depend on various parameters such as: label 

height, number of scans per second, code motion speed, etc. To obtain 

α maximum 

for your application, please contact your Datalogic representative. 
 
You must remember that the decoder will be able to read the label with a tilt angle 
between + 

α max and - α max as shown in Figure 30 (the shaded zones are the NO 

READ zones).
