- Description
The Siemens 6GT2811-7DD20-0AA0 is a SIMATIC RF695R ETSI UHF RFID reader built for high-throughput goods-flow tracking, with eight external antenna ports, Ethernet with PoE, an OPC UA server and an IP33 housing, covering the 865 to 868 MHz band. It runs from 24 V DC drawing up to 2 A, and reaches a 640 kbit/s radio transfer rate across twice the antenna count of the four-port variant.

Selection Notes
Doubling the antenna count to eight over the four-port sibling lets one RF695R cover a wider dock door or multi-lane conveyor without adding a second reader and its own PoE drop. The trade-off is a heavier install: eight RP-TNC runs to plan and terminate versus four, so reserve it for sites where portal width genuinely needs the extra coverage rather than defaulting to the larger reader everywhere.
