2.9 TYPICAL
LAYOUTS
The DS41 barcode reader was specifically designed for industrial
applications. A typical use is real time identification of moving objects on
conveyor belts.
A photoelectric sensor used as a code presence sensor signals when an
object enters the scanner reading zone (see Figure 2.33).

Figure 2.33 - DS41 typical layout
DS41 can be mounted vertically or horizontally to read labels in the two
standard 'picket fence' or 'step ladder' positions. A system can be configured
to read labels in any orientation using several scanners positioned at different
angles.
For each application it is advised that the length of the scan line, the scan
speed, the height of the bars and the code motion speed with respect to the
scanner, allow at least five scans on the code.
The possibility of using raster models allows a greater surface area of the
code to be scanned, increasing the probability of correct reads even if the
code printing quality is poor or the code is positioned incorrectly.
