Notes:
1. Chassis is electrically at ground.
2. Maximum horizontal scan/collection
envelope (denotes max. scan/max. coll in top
views) = nominal scan angle + tolerance.
a.
Two programmable nominal scan
angles: 35°, 47°
b.
Total tolerance = 10°, includes:
i. Scan angle tolerance: ± 3° Typ.
ii. Pointing error: ± 3° Typ.
iii. Pointing shift after 2000G shock:
±1.5º Typ.
3. Maximum vertical scan/collection envelope
(denotes max. scan/max. coll in side views) =
nominal scan line + tolerance.
a.
Nominal vertical scan line: 0°
b.
Total tolerance = 6.5°, includes:
i. Pointing error: ± 3° Typ.
ii. Pointing shift after 2000G shock:
±0.5º Typ.
4. Maximum envelope does not include
integration tolerances.
5. For increased working range at 10,000 FCD,
position opaque material to block ambient
light from entering the zone labeled "Direct
Field of View of Photo Detector."
6. The SE955 scan engine does not require
margin on either side of the bar code to
decode.The 47° scan line provides identical
scanning performance to older scan engines
with a scan line of 53°.
7. Untoleranced dimensions:
.x: ± .5 mm; .xx: ± .25 mm; .xxx: ± .125 mm
8. This is a reference drawing and is not
intended to specify or guarantee all possible
integration requirements for this engine.
