Sick Lector 620 OCR code reader

The Lector 620 OCR code reader is designed for reading and comparing plain text and simultaneous identification of conventional 1D and 2D codes in packaging applications. The most frequent areas of use for the code reader include reading use-by dates and batch numbers on food and pharmaceutical packages, identifying data matrix codes and monitoring the feeding-in of packaging and blanks to packaging machines.

The code reader uses integrated red and blue illumination to ensure optimum lighting of the reading field, regardless of the contrast. The device permits the detection of plain text letters, symbols and numbers at distances of between 30 and 300 mm. This is possible both while stationary and at speeds of up to 4.0 m/s. The integrated text finder ensures that plain text can be reliably read or compared even with printing tolerances on the packaging.

The teach-in of texts is supported by a user-friendly wizard function. No special software is required for teaching-in letters, symbols and numbers because the code reader also has an integrated web server. Fonts can be copied from one device to as many other devices as required (via PC or MicroSD card) for applications in which several code readers carry out the same task.

During operation, the code reader can autonomously adjust reading parameters such as illumination or contrast settings. New fonts and font weights can also be taught-in while machines are running. Its reading reliability is achieved through the use of intelligent decoding algorithms, with which the quality of the code reading can also be evaluated.
