Advanced technology for challenging logistics applications

DataMan 503 Series Features

With the highest read rates in the industry, performance feedback, and no moving parts, the DataMan 503 is suited for the most challenging barcode reading applications and will change the industry’s perception of what can be accomplished with a barcode reader.


Made for challenging logistics applications

The DataMan 503 complements the existing line of DataMan logistics barcode readers and expands the number of applications where image-based readers can be used. It is particularly well-suited for applications that have high speeds, wide belt widths, or large variations in package height. Key DataMan 503 applications include:


Designed to reduce costs and support process improvement

The DataMan 503 includes all of the DataMan features that have set Cognex barcode readers apart, including:


High read rates to increase throughput of the distribution center

DataMan 503 fixed-mount barcode readers achieve the highest possible read rates thanks to a high-speed, dual core processing engine that runs the latest Cognex algorithms at speeds up to 140 Hz.

1DMax® with Hotbars® II and 2DMax® with patent-pending PowerGrid technology decode damaged or poorly printed 1-D and 2-D codes, despite code quality, printing method or surface that the codes are marked on, and can even read 2-D codes without visible perimeters or quiet zones.

  • 2.1 megapixel resolution
  • Fast image acquisition of over 100 frames per second
  • Synchronous multi-camera operation
  • Xpand Technology for applications that require a larger field-of-view

The DataMan 503 series of barcode readers can be used for 1-D and 2-D applications specifically in the logistics industry. Read multiple codes and mixed-codes (1-D & 2-D) simultaneously. Several common barcode reading applications include:


Featured Customer Success Story: Forever 21

DataMan 503 image-based barcode readers are used to sort and deliver items to matching stations. Image-based barcode readers replaced laser scanners to read distorted, low print quality, wrinkled codes at varying angles and positions under plastic packaging. Read rates increased from 95% to over 99% and picking productivity improved by 15% saving approximately $1 million per year.
