What this RFID reader is and where it fits
The Siemens 6GT2811-6CC10-2AA0 is an RF600-series UHF RFID reader operating in the 920-925 MHz band, with a maximum read range of 4 m using the external antenna (1.6 m with the internal antenna, with extended ranges possible per the RF600 System Manual). It communicates over PROFINET IO and EtherNet/IP, and supports DCP and LLDP for network configuration and topology discovery. Power is 24 V DC via an M12 8-pin connector, drawing 0.22 A maximum, 0.2 A typical. The IP67-rated housing in silver/TI-grey Pocan material mounts via VESA 100 with four M4 screws, sized 133 x 133 x 45 mm.
What the ratings mean for fit
The 4 m maximum range with external antenna means this reader can cover a conveyor portal or a pallet entry point without needing a reader at every tag location — but the 1.6 m range with the internal antenna is what you get out of the box, so plan for the external antenna if the application needs the full 4 m. The 920-925 MHz band is the UHF ISM band used in regions like the Americas and parts of Asia-Pacific; verify local frequency allocation before committing the BOM line. IP67 means the reader body and antenna connector withstand washdown and dust ingress — suitable for food-and-bev or outdoor yard applications where hosing down the read point is routine. The 24 V DC supply at 0.22 A max is a light load; a standard 24 V PSU with a few hundred mA headroom covers it without derating concerns.
