Notes:
1. CONTRAST measured as Mean Reflective Difference (MRD) at 650 nm.
2. Near ranges on lower densities (not specified) are largely dependent upon the width of the bar code and the
scan angle.
3. Working range specifications at ambient temperature (23°C), Photographic quality symbols. pitch=10°,
roll=0°, skew=0°, ambient light < 150 ft.-candles.
4. Dependent on width of bar code.
5. Distances measured from front edge of device.

Imaging

MC9500-K with an integrated imager have the following features:
•
Omnidirectional (360°) reading of a variety of bar code symbologies, including the most popular linear, postal,
PDF417, and 2D matrix code types.
•
The ability to capture and download images to a host for a variety of imaging applications.
•
Advanced intuitive laser aiming for easy point-and-shoot operation.
The imager uses digital camera technology to take a digital picture of a bar code, stores the resulting image in its
memory, and executes state-of-the-art software decoding algorithms to extract the data from the image.
