EX20 Near/Far Image Engine Reading Distances
The depth of field measurements were taken using these parameters:
• Distances are measured from the front of the engine.
• +23 °C (+73 °F), 0 lux
• Photographic quality codes
Note: Time to Read and Depth of Field are impacted if the bar code symbol is at the edge of
the image.
White Illumination Monochrome Sensor Only
EX20 Imager Engine Field of View/Resolution
Note: DPI can be calculated based on the following formula:
Horizontal DPI = 832 pixels/width of horizontal field of view (inches)
Vertical DPI = 640 pixels/width of vertical field of view (inches).
