The (theoretical) line speed LS can be calculated using the following formula:
0.8 X / T
exp
= LS
LS = 0.8
*
(X/T
exp
) Where: LS = line speed (in mm/s)
X = code module width (in mm)
T
exp
= exposure time (in s)
Examples:
For TC1200, T
exp
max is = 300 s with No Ambient Light (0 Lux) and Strobed Exposure Mode.
Using the maximum exposure time of 300 s, the following line speeds can be obtained
depending on the code resolution:

0.508/300 s] = 1354 mm/s
14 mils

0.356/300 s] = 949 mm/s

0.305/300 s] = 813 mm/s

0.254/300 s] = 677 mm/s

0.203/300 s] = 541 mm/s
