3.2 - Reading Features

500 mm/s performs:

[(25/500)

350] - 2 = 15 effective scans.

3.2 PICKET-FENCE MODE

Code motion direction

at LS speed

Laser beam

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 180 mm wide at a 1300 mm/s speed, the DS1100 (350 scans per

sec.), performs:

[((180-50)/1300)

350] - 2 = 33 scans

1 2 ... 25 26 27 28 29 30 31 32 33 34 35 36 37 38
