Noise Level
5.0 VDC ±10%
95 mA typical; 125 mA max
27 mA typical; 50 mA max
200 mV peak-to-peak max.
Laser Power 1.5 mW typical,
λ
= 650 nm nominal
Scan Rate 104 (±12) scans/sec (bidirectional)
Print Contrast Minimum 25% absolute dark/light reflectance measured at 650 nm.
Scan Angle Default (Wide): 47° ± 3°
Alternate (Narrow): 35° ± 3°
Note: The Symbol MS954 does not require margin on either side of the bar code to
decode. The 47° scan line provides identical scanning performance to older
minscans (e.g., Symbol MS923) with a scan line of 53°.
