DS2400 DATALOGIC
3.2 -
Technical Features
For example, the DS2400 (800 scans/sec.) for a 25 mm high code moving at
1250 mm/s performs:
[(25/1250)
*
800] - 2 = 14 effective scans.
3.2 PICKET-FENCE MODE
If scanning is parallel to the code motion, (Figure 3.2 - "picket-fence" mode),
the number of effective scans is given by the following formula:
SN = [((FW-LW)/LS)
*
SS] -2
Where: 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
Code motion direction
at LS speed
Laser beam
Figure 3.2 - "Picket-Fence" scanning mode
For example, for a 100 mm wide code moving in a point where the reading
field is 200 mm wide at a 2000 mm/s speed, the DS2400 (800 scans per
sec.), performs:
[((200-100)/2000)
*
800] - 2 = 38 scans
