Siemens 6GT2811-6AA10-0AA0 SIMATIC RF680 RF680R ETSI 4-Antenna PROFINET RFID Reader

The Siemens 6GT2811-6AA10-0AA0 is a SIMATIC RF680R ETSI UHF RFID reader with four external antenna ports, an integrated OPC UA server and PROFINET/Ethernet/EtherNet-IP connectivity, covering the 865 to 868 MHz band with an IP65 housing. It runs from 24 V DC, switches four digital inputs and four digital outputs directly, and supports Media Redundancy Protocol for ring-topology networks.

Selection Notes

The RF680R's four antenna ports and 2000 mW maximum transmit power make it the choice for read zones covering multiple portal sides at once, where a single- or dual-antenna reader in the same family would need extra hardware to get the same coverage. Its four digital inputs and outputs let it trigger a light stack or gate directly from a tag event without routing that signal through a PLC first, and the onboard OPC UA server exposes tag reads to a SCADA or MES system without a separate protocol gateway.
