Master DS457-HD20009 Fixed 2D Mount Barcode Scanner USB Cable

Fixed 2D Mount Scanner

The Master DS457-HD20009 is a fixed-mount 2D barcode reader supplied with a USB cable and power adapter. It is designed for hands-free scanning in kiosks, assembly lines or point-of-sale stations where items pass a stationary window. The unit reads two-dimensional codes from surfaces or screens without requiring operator alignment.

Continuous Operation Behaviour

As a fixed-mount device, the scanner is built for sustained, repetitive reads rather than occasional hand-held use. Its stationary optics and external power supply allow it to maintain consistent decode rates across long shifts without battery constraints or operator fatigue affecting aim. The USB connection provides a stable host link for continuous data streaming.

USB Interface Limits

The USB cable delivers both communication and power within the limits of the standard USB specification used by the host. Cable length restricts placement distance from the host PC or controller, and the fixed focal range determines the working window size for reliable decoding. No wireless or network interfaces are included.
