Cognex 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. Furthermore, 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. It 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 barcode readers are 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.
