Multi-interface connectivity — USB, Serial, Keyboard Wedge, and IBM 46XX — distinguishes the Datalogic M3301-010200 as a flexible in-counter barcode reader for high-volume point-of-sale installations. Its LED-illuminated area imager resolves codes down to 5 mil at a scanning distance of 4 in, reading both 1D and 2D symbologies including Aztec Code, Data Matrix (ECC200 Only), MaxiCode, QR Code, PDF417, MicroPDF417, and the full GS1 DataBar family — stacked, expanded stacked, composites, and omnidirectional variants. The unit supports sweep and presentation scanning techniques and autodiscriminates all standard 1D linear codes. At 1.75 lb with a 6-in height, 6-in width, and 3.4-in depth, it fits standard countertop cutouts. RoHS and China RoHS compliance is confirmed, and the scanner carries a 3-year limited warranty.
