TI for metal applications two low frequency RFID products

July 2008 10, Texas instruments (TI) announces 12 mm multi-purpose wedge-shaped transponder and 24 mm low frequency circular electronic label, further expanded its low-frequency product family camp.

12 mm multi-purpose wedge-shaped transponder on chip circuit improvements that can be directly installed in the metal, and 24 mm low frequency circular tag is used TI patent tuning process, to improve waste management and industrial production, application of read and write consistency. Since the late 1980s, the low-frequency RFID technology 134.2 kHz is used from livestock to auto parts, such as the identification of any object. At present, many new types of applications require labels on high metal environment or other harsh industrial environment with better performance.

TI's label uses include half-duplex (HDX) radio communication technology, a series of RFID patent technology and implements the quality innovation.

With full duplex (FDX) compared to low-frequency technology, HDX extend not only to be read by 50%, but also to provide stronger radio frequency (RF) signal because the HDX reader during the HDX label response may shut down. In this way, the HDX reader can focus accepts signals, thus more than FDX accurate readings. For FDX, the reader is always state of the signal, in an attempt to read FDX labels may cause radio interference. In addition, the HDX also adopts shift keying technique, this will not only make TI's label has superior resistance to electromagnetic interference (EMI), but also enables the reader to read and to distinguish between each other effectively close tag.

Brooks Automation (Germany) company's research and Development Director, turning to low-frequency HDX TI technology use experience, said: "our customers ' requirements are higher, they called TI-frequency technology is the HDX technology can provide excellent performance.

TI's MUSA transponder is not responsible for the look, we find that the device not only excellent anti-vibration ability, but also inThe customer's high performance metal environment is excellent. ”

TI's new label for worst application environments, such as waste disposal container tracking, vehicle identification and access control, and oil refineries, oil drilling and machine tool manufacturing and other high metal environment applications.

New labels can also be used for carbon fiber products, including aerospace, automotive and bicycle parts and components, and can withstand the high temperatures in the manufacturing process.

TI RFID systems Department is responsible for asset tracking of Director Mikael Ahlund pointed out: "we made from metal, temperature and noise environment and difficult to use other technology applications recommended the use of low-frequency HDX technology.

Our low-frequency product series for performance and quality, continuous innovation to ensure that this technology has been continually extended to apply to more new areas, in particular the high metal environment as well as other challenging RF environments. ”

In addition to direct mounting on metal surfaces, TI 12 mm multi-purpose wedge-shaped transponder also has excellent resistance to electromagnetic interference ability and in industrial application can be excellent resistance and other typical surrounding noise.

In addition, the transponder also has 208-bit flexible user programmable memory and enables users to build on the application of a certain security level of password write-protect feature. For example, a user can use the label part of memory into the factory locked numbers, such as the manufacturer's identification code. Other data area can be flexibly used to record the asset life cycle status, maintenance and update information. The password can be set up by certain security, this data is updated only by authorized personnel.

24 mm low frequency circular tag with 80-bit read/write memory and 64-bit read only memory.

Electronic tag to ISO/IEC 11785 criteria and can be easily accomplished using a variety of materials for small package. Electronic label after complete inline parameters and functional testing, and continuously improve yield. These two new products with TI's reader series compatible. TI's HDX tag and the reader is the perfect combination to provide optimal performance, and it is easy to install and use.

TI's product range covers 134.2kHz low frequency 40 multiple transponders, electronic tags, antenna and reader product is TI 20 years RFID experience in design and manufacturing.
