Fixed-Mount 1D/2D Barcode Scanner

The B+n DS457-SR20004ZZCN reads both one-dimensional and two-dimensional codes from a fixed position. It connects over USB for simple integration into point-of-sale, manufacturing or access-control systems. Workers present items continuously without pausing between scans.

USB Interface Practical Limits

The scanner relies on a wired USB connection for power and data, so cable length and host port placement dictate mounting options. No wireless or alternative interfaces are supported, limiting flexibility in layouts where cabling is difficult.

Compact Installation and Common Issues

At 1.15 in. H x 2.3 in. L x 2.44 in. W the unit fits in tight spaces such as under-counter registers or kiosk enclosures. Alignment with the scan window is critical; misaimed mounts or reflective surfaces can reduce first-pass read rates on phone screens or direct-part marks.

Questions about this item

Which mounting orientation works best for the DS457-SR20004ZZCN given its 2.3 in. length and 2.44 in. width?

At 2.3 in. long by 2.44 in. wide, the scanner fits under counters or on registers in either portrait or landscape orientation without protruding into the work area.

How does the 1.15 in. height affect scan speed when items are passed quickly across a conveyor?

The low 1.15 in. profile keeps the scan window close to the presentation plane, so the imager captures 1D and 2D codes at full speed without pauses between scans.

What does the USB interface limit in terms of cable routing and power for this fixed-mount unit?

USB supplies both data and power through a single cable, so routing stays simple and no external adapter is needed; cable length follows standard USB limits.
