See code-verification vision sensor at MTEC 2011On Stand 1228 at the MTEC Exhibition (6/7 April 2011 at the NEC, Birmingham) Balluff will be showing its new BVS-E Identification vision sensor for detecting and identifying 1D codes (barcodes) and 2D codes (Data Matrix). The Balluff BVS-E Identification vision sensor reads the commonly found codes and can even verify texts and number sequences. It also reads multiple codes in one pass to avoid repeated read cycles and the need for multiple sensors. It even 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 barcodes, the popular 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.

Balluff's BVS-E Identification is particularly useful for reading multiple codes simultaneously. This feature is often used in applications where, in addition to a barcode, a Data Matrix code and plain text marking are used. The outstanding read performance of the BVS-E Identification is also boosted by the 360-degree Locator tool, which means that labels no longer needing to be exactly aligned.

Integrating a BVS-E Identification vision sensor in new or existing automation applications is said to be simple, as operation and start-up are handled using the free, easy-to-use ConVis software. The entire process is guided and requires no knowledge of programming language or expensive 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 configuration for 1D and 2D code detection, reducing costs and increasing quality.
