Design of the Scanner Opening
A typical system uses the scanner mounted inside a host enclosure with an opening for
the scanner Field of View to exit the scanner window and read bar codes. If the scanner
is flush against the opening, it should be the size of the scanner window at a minimum,
but only exposing as much of the front surface of the scanner as necessary. Additional
clearance in the opening can also be considered for the speaker opening.
The design and placement of the scanner opening within a host enclosure is critical for
optimum system performance. Use the detailed dimensions shown in
Mechanical Specifications
with the following guidelines.
• The opening must not block any of the outgoing illumination light, described by
• Ensure that there are no reflective surfaces around the area of the scanner opening.
• The minimum opening size must increase as the distance between the scanner and
• The opening or other parts of the host enclosure must not enter the Field of View
