Siemens 6GT2 801-2AA10 Sensor

The Siemens RF340R (6GT2 801-2AA10) is an RFID reader/detector in the RF300 Matrix designed to identify passive ISO tags in the 13.56 MHz band. It communicates to a host controller via RS-232 or RS-422 and operates from an external DC supply in the 10–30 V range. Siemens notes that only one RF340R reader may be connected per COM port, making it straightforward to wire into existing serial control networks. As part of the RF300 family, the RF340R supports ISO-tag identification with passive tags, enabling reliable identification and simple integration in industrial environments where tag-based asset identification is required. The model is cataloged as RF340R under the 6GT2 801-2AA10 designation and is referenced across Siemens documentation and distributor listings as the RF340R variant for ISO-tag systems. For extended connectivity or networked deployments, Siemens and partner configurations in the RF300 ecosystem include interface converters and manager components that support integrating the RF340R with other controllers or IP-based interfaces. In practice, this channel-friendly reader provides a compact, serial-focused path to add RFID identification to automation tasks without proprietary tag requirements, making it suitable for applications such as equipment tracking, inventory identification, and workflow automation where passive ISO-compliant tags are used.
