Barcode readers read damaged 2D codes
Cognex Corporation (NASDAQ: CGNX) 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 the company said, the barcode readers are unaffected by variations in lighting, marking method, code quality or surface finish.
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.
The DataMan 100 and 200 readers have 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.
