Cognex DataMan ID Readers

Thanks to advances in microprocessors, imaging sensors and decoding algorithms, image-based ID readers have become not only more affordable, but also more powerful than traditional laser scanners.

Image-based readers view the entire barcode, not just a single line, so they can overcome various barcode defects better than laser scanners. Image-based readers can also read barcodes in any orientation and can decode 2-D (two-dimensional) symbologies like Data Matrix and QR.
With these advantages, image-based readers achieve higher read rates than laser-based scanners. As opposed to laser scanners which require moving parts to generate a laser line, the DataMan® does not. This means no parts that wear out, subsequently providing long term reliability and low maintenance.

With Cognex’s PowerGrid technology, we can locate and read 2D codes even when they exhibit significant damage to or complete elimination of the finder pattern, clocking pattern or quiet zone. This provides you with a robust system to read damaged codes and less time to rework these damages.

And with Cognex’s Hotbars II technology, we can improve read rates of 1D codes at high speeds to read the most challenging barcodes even down to 0.8 pixels per module. This means high reliability, better efficiencies and throughput for you.

With Cognex’s High Dynamic Range (HDR) imaging that uses the latest CMOS image sensor technology which is 16 times more detailed than conventional sensors. HDR takes advantage of the extra available image data to globally enhance image quality and contrast.
