Image based barcode reader offers superior performance to laser scanners

13 January 2011

Cognex Corporation's new DataMan 500 image-based barcode reader offers higher read rates, improved on-line visualisation and higher reliability compared with laser scanners. Using Cognex IDMax code reading software, DataMan 500 can read damaged, distorted, blurred, scratched, low height and low contrast codes in any orientation, and processes images at up to 1,000 frames per second with 2D codes such as Data Matrix and QR, and multiple codes in the same image.

DataMan 500 offers a wide range of additional benefits including auto-trigger, auto-focus and “no read” feedback. The base unit will support both standard C-Mount lenses as well as variable focus options. The auto-focus is achieved using liquid lens technology, which provides maximum operating range flexibility for even the highest speed applications. This proven new technology, already integrated into Cognex industrial readers, is fast and reliable and offers good optical quality with low power consumption.

Key to successful implementation of any barcode reading application is ease-of-use and the integration tools available. DataMan 500 has been designed to be as easy to use as a laser scanner. In addition, the “no read” feedback and visualization features make validating the code reading setup very straightforward and allow any reading issues to be quickly diagnosed and corrected.

To simplify the installation, DataMan 500 combines Ethernet communication and power delivery in a single cable using Power over Ethernet (PoE). DataMan 500 also supports RS-232 and multiple I/O points for integration into legacy systems.
