VISOR Code reader
With its integrated object detection, the VISOR® Code Reader is unique in its price segment. The compact sensor reads conventional 1D bar codes, 2D data matrix codes and now also optical characters (OCR). It also has four detectors for object detection (pattern comparison, brightness, grey level and contrast), with which other object features – for example, stamps or logos – can be evaluated in a single reading pass. Codes and object features are even reliably detected with deviations from the taughtin position – using position tracking (optionally activated).
A special image filter with expanded setting options guarantees excellent reading performance even under difficult reading conditions.
The test results can largely be evaluated within the sensor itself – with the option of string comparison or regular printouts – so that there is no need for a PLC or PC connection in many cases. If, however, this proves necessary, it can be easily and flexibly connected using freely available PLC function blocks for Siemens S7, Codesys and Allen Bradley.
In addition, the robust, compact and industry-oriented housings guarantee reliability even where space is restricted. Integrated 6 mm or 12 mm optics or C-mount devices also save effort and costs through their optimum adaptation to the most varied of code sizes and operating distances. The new V20 variants also offer a resolution of 1.3 megapixels for particularly small codes or large search areas.
Special features of the VISOR® Code Reader
• Can be used for all common 2D codes (e.g. ECC 200 data matrix) and common 1D bar codes
• Optimum cost-effectiveness through combination of two functions in one device: code reading and object detection
• High operating dependability through reliable detection of even poorly readable codes under difficult ambient conditions
• Flexible and simple connection to PC and PLC environments due to comprehensive possibilities for archiving pictures and read results, as well as freely available PLC function blocks for Siemens S7, Codesys and Allen Bradley
• Very high flexibility, e.g. also due to reading several similar or different codes in one reading pass
• Reading of optical characters with OCR based on neuronal networks, particularly suitable for point printing
