Intermec ED40 - EA20 X Reading Distances; Typical Reading Distances

Appendix B — EA20X Imager
ED40 Decode Board Integration Guide 83
EA20X Reading Distances
All distances are measured from the front of a non-integrated scan engine using
Grade A symbologies and an Intermec decoder. Scan rate is 30-60 frames/sec
depending on laser framing management. An exit window will reduce reading
distances by about 4%.
Typical Reading Distances
These are typical reading distances measured in an office environment (250 lux).
