MS-1207WA Specifications
MS-1207WA Decode Zone
The MS-1207WA Wide Angle decodes symbols as shown in Figure 3-3 . Typical values are
shown. Table 3-3 on page 3-8 lists the typical and guaranteed distances 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 Method on page 2-14.
