2.7 – Decoded Scan Engine Mechanical Specifications
The CR822x has 4 blind mounting holes for use with self-tapping screws.
Overall Dimensions
2.8 – Enclosure Specifications
1. The enclosure for the CR822x should be large enough to
accommodate the engine and designed to maintain the ambient air
in contact with the CR822x within its operating limits (Note: special
care should be taken to ensure the temperature at the image sensor
does not exceed 70 ºC and the temperature at the processor does
not exceed 100 ºC). The enclosure should minimize infiltration by
airborne contaminants and foreign materials.
2. The CR822x must not come in contact with water.
3. The CR822x is sensitive to Electrostatic Discharge (ESD) and must
be handled appropriately. Any individual who handles the CR822x
should be grounded using a wrist strap and ESD protected work area
and work surface.
4. The warranty of the CR822x is void if the recommendations above
are not followed when handling or integrating the device.

3.1 – Window Requirements
When integrating the CR822x into your device or application, it may
be necessary to install a window in front of the optics of the Imager.
Although many different types of materials can be considered, Code
makes the following recommendations.
Placement: Contact to 0.5 mm away from the face of the Imager,
parallel to engine face
Material: Optically clear acrylic
Thickness: 1 mm or less
If your design constraints prevent the window from being mounted within
0.5 mm of the face of the engine, Code recommends an anti-reflective
(AR) coating be applied to both window surfaces (front and back). The AR
coating must have less than 3% reflectance from 400nm to 1000nm.
The window must be wide and tall enough so the surrounding enclosure
does not block any of the illumination from the LEDs. The following
diagram illustrates the field of illumination that must be unobstructed
by the edges of the window aperture.
