Symbol MS1204FZY Decode Zone

The scanner has a selectable scan angle of either 30° or 42°. The 42° symbol decodes are shown in Figure 4-5. The

figures shown are typical values. Table 4-3 on page 4-8 lists the typical and g uar ante ed 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 is

shown below. To calculate this distance, see Calculating the Usable Scan Length Methodon page 2-8.
