Figure 3.2 - "Picket Fence" scanning mode
If scanning is parallel to the code motion, (Figure 3.2 - "picket fence" mode),
the number of effective scans is given by:
SN = [((FW-LW)/LS) * SS] -2
These symbols signify:
SN
= number of effective scans
FW
= reading field width (in mm)
LW
= label width (in mm)
LS
= label movement speed (in mm/s)
SS
= scans per second
For example, for a 50 mm wide code moving in a point where the reading
field is 100 mm wide at a 1000 mm/s speed, the DS2200 (500 scans per
sec.), performs:
[((100-50)/1000) * 500] - 2 = 23 scans
3.3 PERFORMANCE
The DS2200 scanner reads codes with densities from 0.15 mm (6 mils) to 1
mm (40 mils) in the zone between 50 mm (1.9 in) and 220 mm (8.6 in) from
the emission window.
The DS2200 has a scanning speed of 500 scans/sec.
The max. capture of the raster version is about 15 mm (0.6 in) at 220 mm
(8.6 in).
