Direct Part Marking capability defines the Datalogic PD9531-DPM, a corded handheld area imager built for manufacturing environments where codes are etched, dot-peened or ink-jet printed directly onto components rather than applied as paper labels. Its high density optics cover a reading distance from contact to 15.0 cm / 5.9 in for standard printed barcodes, while DPM reading operates from contact to 4-5 cm / 1.5-1.9 in depending on surface type and code resolution. The imager autodiscriminates all standard 1D codes including GS1 DataBar linear codes and decodes a full 2D symbology set -- Aztec Code, China Han Xin Code, Data Matrix, MaxiCode, Micro QR Code and QR Code -- alongside PDF417, MicroPDF417, MacroPDF, nine postal formats and a complete range of stacked and composite codes. Host connectivity covers USB, Serial and Keyboard Wedge interfaces. The black and yellow handheld chassis measures 8.3 in tall, 2.9 in wide and 4.3 in deep, weighing 11.64 oz, and is manufactured in Slovakia.
