Compact fixed-mount barcode reader

The B+n DS457-SR20004ZZCN is a small fixed-mount scanner built for tight spaces such as retail counters, manufacturing cells or airport gates. It reads both 1D and 2D codes plus direct part marks without pausing between scans. Workers can capture codes as fast as items are presented, keeping throughput high.

RS-232 serial interface

The only data connection is an RS-232 port, so the host system must provide a matching serial port or a compatible adapter. Buyers whose equipment uses only USB, Ethernet or wireless links cannot connect this unit without extra conversion hardware.

Simple bracket mounting

At 1.15 in high by 2.3 in long by 2.44 in wide the scanner fits into very small cut-outs and can be attached to a register or tucked under a counter. Installation usually fails when the mounting surface is uneven or when the RS-232 cable length does not reach the host port.
