Enclosure Specifications
The imaging engine was specifically designed for integration into custom housings for OEM applications. The
imaging engine’s performance will be adversely affected or permanently damaged when mounted in an
unsuitable enclosure.
Warning: The limited warranty (on page 49) is void if the following considerations are not adhered to when
integrating the area-imaging engine into a system.
Electrostatic Discharge (ESD) Cautions
All engines and decode boards are shipped in ESD protective packaging due to the sensitive nature
of the exposed electrical components.
• ALWAYS use grounding wrist straps and a grounded work area when unpacking
and handling the engine.
• Mount the engine in a housing that is designed for ESD protection and stray electric fields.
ESD has the ability to modify the electrical characteristics of a semiconductor device, possibly
degrading or even destroying the device. ESD also has the potential to upset the normal operation
of an electronic system, causing equipment malfunction or failure.
Airborne Contaminants and Foreign Materials
The imaging engine has very sensitive miniature electrical and optical components that must be protected from
airborne contaminants and foreign materials. In order to prevent permanently damaging the imaging engine
and voiding the limited warranty (on page 49), the imaging engine enclosure must be:
• Sealed to prevent infiltration by airborne contaminants and foreign materials such as
dust, dirt, smoke, and smog.
• Sealed to protect against water, humidity, and condensation.
