Image-based bar code reading outperforms laser scanners

New exhibitor to ProMat, Cognex is showcasing its DataMan 500 image-based bar code reader in Booth 768.

Using patented software, the system reads 1D bar codes that laser readers cannot—including damaged, distorted, blurred, scratched, low-height and low-contrast codes—explained Matt Engle, strategic market development manager.

“The technology accommodates packages of indeterminate size, with labels located anywhere, by incorporating a long range depth of field,” said Engle. “The unit quickly selects its plane of focus using liquid lens auto-focus technology, while its imager acquires and analyzes images at 1,000 frames per second.”

Further, the device can read codes in any orientation, 2D codes such as Data Matrix and QR, and multiple codes in the same image, he continued.

“It’s easier to use than a laser scanner and allows users to see what the reader sees—either live on a monitor, or via image archiving,” he said. The DataMan 500 also has no moving parts, making it more reliable than laser scanners, Engle concluded.

ProMat 2011 will be held March 21 - 24, 2011 at McCormick Place South in Chicago. The tradeshow will showcase the latest manufacturing, distribution and supply chain solutions in the material handling and logistics industry. Modern editors produce the Show Daily for the show.
