SE1524 Long Range Laser Decode Zones
Typical decode ranges are shown in Figure A-2. Table A-4 on page A-8 lists the typical distances for the SE1524
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.
