Symbol MS1207FZY Specifications 4 - 7

Symbol MS1207FZY Decode Zone

The scanner has a selectable scan angle of either 30° or 42°. Figure 4-5 shows the 42° symbol decodes. The figures

shown are typical values. Table 4-3 on page 4-8 lists the typical and guaranteed distances for the 42° scan angle

for selected bar code densities. The minimum element width (or “symbol density”) is the width in mils of the

narrowest element (bar or space) in the symbol. The maximum usable length of a symbol at any given range

appears below. To calculate this distance, see Calculating the Usable Scan Length Method on page 2-8.
