Turck is presenting the world's only HF read/write head with Ex-m protection for contactless identification in explosion-protected areas

RFID Read/Write Head for Ex Zone 1/21

Turck is presenting the world's first HF RFID read/write head for direct use in ATEX Zone 1/21

Turck is expanding its Industry 4.0 portfolio into explosion-protected areas and is thus underlining its commitment to being a supplier of end-to-end IIoT solutions for the process industry. With the TN-R42/TC-Ex, the automation specialists are not only offering the world's only HF RFID read/write head certified for direct use in ATEX Zone 1/21, but also a reliable and simple alternative for applications where previous implementations were impossible or very difficult. 

Your Benefits

  • Improved plant safety: Valves only open once the correct hose connections are correctly identified 
  • High quality standard: reliable identification and documentation of pre-products and intermediate products
  • Track & trace: complete traceability of products via comprehensive RFID use
  • Protection against manipulation: matching of specific RFID data instead of inductive binary code detection

Robust, compact and installable virtually anywhere

The read/write head stands out from flameproof identification solutions for Zone 1/21 on account of its extremely compact dimensions and can therefore also be installed in applications where space is restricted. The slim-line TN-R42/TC-Ex is therefore ideal for the contactless identification of correct hose and flange connections, which ensure investment and product quality in the chemical and pharmaceutical industry. 

End-to-end HF RFID system in the Ex area 

The interface connection of the TN-R42/TC-Ex operates like a standard read/write head for the safe area. It is simply connected to Turck's BL20 or TBEN RFID interface series and can also be installed in protective housings in Zone 2/22 if required. It can also process other information in addition to hose identification, such as socket, data, time or the degree of hose contamination. Turck's multiprotocol technology enables data transfer to the control system via three Ethernet protocols – Profinet, EtherNet/IP and Modbus TCP.

Application specific RFID tags

Different HF RFID tag types adapted to specific application requirements are available. For example, HF RFID tags with a password function are available for applications with demanding requirements with regard to data security and access protection.

Complete traceability thanks to a comprehensive RFID system 

Turck's comprehensive HF RFID system provides an optimum solution for different identification tasks in the pharmaceutical industry. It guarantees improved plant safety and the complete traceability of products thanks to the end-to-end use of RFID.
