Barcode readers feature 2D matrix technology
September 6, 2012
Cognex Corporation (www.cognex.com), the global leader in Industrial ID, has integrated advanced 2DMax+™ code reading software technology into the compact DataMan® 100 and 200 fixed-mount barcode readers. With 2DMax+, the readers can now identify and decode severely damaged or poorly marked 2-D matrix codes. Most importantly, the barcode readers are unaffected by variations in lighting, marking method, code quality or surface finish.
“2DMax+ is a proven breakthrough in 2-D decoding and is based on our existing patented, industry-leading software,” says Carl Gerst, vice president and business unit manager, ID Products. He continues, “Following the success of 2DMax+ in the advanced DataMan 300 and 500 series of fixed position barcode readers, we are now delivering it to end users who need a smaller form factor. This functionality is especially helpful in the food, beverage, pharmaceutical and consumer goods packaging sectors. Barcode reading in these industries are often challenging due to poor print quality, varying part sizes, curved surfaces and labels damaged by environmental factors or supply chain activity. 2DMax+ helps these users achieve the highest reading yields and maximize throughput.”
Though Data Matrix codes have built-in error correction, “no-reads” can still occur when codes are incomplete. 2DMax+ can read Data Matrix codes even when critical elements are missing. 2DMax+ can also locate and decode Data Matrix codes that are overexposed or underexposed, without requiring multiple retries. This improves throughput, speed and overall reliability.
The DataMan 100 and 200 readers are exceptionally small with an industrial-rated housing measuring just 23 x 42 x 64mm. The DataMan 200 series incorporates variable focus liquid lens technology for applications that require a larger depth of field or refocusing after a product changeover. The DataMan 200 models also support Ethernet connectivity with a wide range of industrial protocols, for real-time part tracking, image archiving, data transfer and seamless integration with plant controllers and information networks. The DataMan 100 series provides USB and RS-232 communication options.
The 2DMax+ algorithm is now shipping with all DataMan 100X and 200X models as well as the DataMan 300X and 500X readers.
