Notes:
1. Measured scanning a symbol with 0.19 mm narrow elements. For larger narrow element widths, the maximum scan speed will
increase proportionally.
2. Contrast is defined as R_W-R_B where R_W is the reflectance of the white spaces and R_B is the reflectance of the black bars, measured at
880 nm.
3. Allowable power supply ripple and noise is frequency dependent. See Figure 5.
4. Non-condensing. If there is frost or dew over the optics window, it should be removed for optimal scanning performance.
5. Direct sunlight at any illumination angle.
6. The shield must be properly terminated (See Figure 2). The human body is modeled by discharging a 300 pF capacitor through a
500 Ω resistor. No damage to the slot reader will occur at the specified level.
