Configured for 1D-only decoding, the Datalogic M3303-010120 is an in-counter bar code reader from the Magellan 3300HSI family that pairs a laser light source with an imager sensor to deliver omni-directional scanning at a maximum resolution of 5 mil and a scanning distance of 4 inches. It autodiscriminates all standard 1D linear codes including GS1 DataBar linear codes, and also reads 2D symbologies -- Aztec Code, Data Matrix, MaxiCode and QR Code -- along with stacked codes such as PDF417, MicroPDF417, GS1 DataBar Stacked, GS1 DataBar Stacked Omnidirectional, GS1 DataBar Expanded Stacked and GS1 DataBar Composites. Host interfaces include USB, Serial, Keyboard Wedge and IBM 46XX, with the USB cable sold separately. The black in-counter housing measures 6 inches wide by 6 inches tall by 3.4 inches deep and weighs 1.75 lb, suited to high-volume point-of-sale counter installations.
