Balluff Vision Sensor Identifies 1D and 2D Codes

At the MTEC Exhibition, Balluff will be showing its new vision sensor for detecting and identifying 1D codes (barcode) and 2D codes (Data Matrix). The Balluff BVS-E Identification reads the commonly found codes and can verify texts and number sequences. It also reads multiple codes in one pass, saving repeated read cycles and eliminating the need for several sensors.

It works reliably under challenging conditions, such as directly imprinted parts that can often present a special challenge, for example when they are applied to cast materials or reflective surfaces. Balluff vision sensors have the footprint of a credit card and are available with built-in processing electronics, lighting and digital outputs. Once configured they run autonomously.

The results 'Inspection OK' or 'Inspection NOK' are available directly on the digital outputs. An RS232 or Ethernet interface can be used to output the code data and trace processed parts. The range of readable codes includes, in terms of barcode, the Interleaved 2-of-5, Code 39, Code 128, Pharmacode, Codabar and EAN 8 to EAN 13 UPC-E. Using OCV (Optical Character Verification), even texts or number sequences can be verified based on learned pixel patterns. The new BVS-E Identification shows its special ability when reading multiple codes simultaneously.

This feature is often used in applications where, in addition to barcode, Data Matrix code and plain text marking are used, eliminating the need to use multiple specialised sensors. The read performance of the BVS-E Identification is also boosted by the 360deg Locator tool, as labels no longer needing to be exactly aligned. According to Balluff, integrating BVS-E Identification in new or existing automation applications is simple, with operation and start-up handled using the free Convis software. The entire process is guided and requires no knowledge of programming language or training.

Users of Eplan CAD and CAE software can download the macros for the BVS Vision Sensors from the Balluff website at no charge and use drag-and-drop for 1D and 2D code detection, reducing costs and increasing quality. Vision sensors form part of the Balluff product range. Balluff's sensors can be used in a variety of applications, including pill counting, package presence, fill levels, clear bottle detection, data tracking and error proofing.
