The DataMan 100 QL and DataMan 200 QL fixed mount 1D barcode readers from Cognex easily read codes that laser barcode scanners fail to read, such as marks that are low contrast, damaged, or distorted by severe perspective.
The QL series features 1DMax™, a totally new 1D code reading algorithm.
1DMax handles quiet zone violations that can occur when codes are
printed close to the edge of a label. DataMan QL readers are easy to
deploy using the system’s Setup Tool which also includes an image
archiving feature enabling users to store images of read failures in
order to diagnose the cause of a problem.
