Siemens 6GT2002-1HD01 SIMATIC RF RFID Connection Block

Siemens 6GT2002-1HD01 SIMATIC RF RFID Connection Block is a purpose-built accessory that mates with the RF170C RFID module to attach two RFID readers through two M12 plug-in connectors. It provides RS-422 or RS-232 communication paths from the RF170C to each reader, making it the two-reader expansion block within the SIMATIC RF HF RFID family. The device is documented by Siemens as the RF170C-compatible connection block for connecting two readers, and it is listed by distributors as the standard option for expanding read head count in RF170C deployments. In practice, the 6GT2002-1HD01 is used in configurations where multiple HF readers must interface to a single RF170C module, enabling coordinated tagging workflows and flexible cabling layouts in automation installations. As part of the SIMATIC IDENT/RFHF portfolio, this block integrates with RF170C-based systems and supports the established RS-422/RS-232 interfaces that connect readers to the RF170C module, helping to streamline installation and maintenance in production environments.
