Mainly the thinnest bar and space width that is
used to print the bar code determines the read range.
However, there are other factors that may have an
influence on the read range such as how well the
dimensions of a printed bar code are in compliance with the printing tolerances
according to the specification of that particular bar code type.
Typically the ‘size’ of the printed bar code is expressed as the width of its
narrow elements (both bars and spaces). The width is measured in mils –
thousandths of an inch. (For example, 40 mils in inches are 0.04, in millimeters it is
1.01.) The bar code scanner on the PL3000 is capable of reading all the supported
barcode types
of any mils
from
the shortest distance of 5cm
, approximately.
The longest read distance
varies according to the size of a bar code. The
distance ranges from
14cm with the 4-mil bar codes to 80cm with the 20-mil
and greater
bar codes.
2-D Symbology Reader
The imager supports the width-modulated linear symbologies, the hight-
modulated linear symbologies, the 2-D stacked symbologies, the 2-D matrix
symbologies, and the composite symbologies as follows:
