SE965 Decode Zone

The table lists the typical distances for selected barcode densities. The minimum element width (or “symbol density”) is the width in mils of the narrowest element (bar or space) in the symbol.

Contrast is measured as Mean Reflective Difference (MRD) at 650 nm. Working range specifications at temperature = 23°C, pitch=18°, roll=0°, skew=0°, photographic quality, ambient light ~150 ft-c, humidity 45-70% RH. Dependent upon the width of the barcode. Distances measured from the front edge of scan engine chassis.
