What this reader is and where it fits
The Siemens 6GT2811-6AB20-2AA0 is a UHF RFID reader from the RF600 series, operating in the 920-925 MHz band with a maximum read range of 8 m. It supports DCP (Discovery and Configuration Protocol) for automatic device addressing on PROFINET networks, LLDP for topology discovery, and OPC UA for higher-level data exchange — making it a fit for automated material flow and asset tracking lines where the reader must integrate into a managed industrial network. The reader draws 0.37 A typical and 2 A maximum at 24 V DC, supplied through an M12 8-pin connector. It includes 4 digital inputs and 4 digital outputs for direct connection to conveyor sensors or actuator controls without an extra I/O block.
Mounting and environmental constraints
Mounts on 35 mm top-hat DIN rail or profile rail for S7-300/1200/1500, plus VESA 100 with four M4 screws. The aluminum and Pocan housing is rated IP30 — suitable for indoor cabinet installation, not washdown zones. Operating temperature range is -25 to +55 °C; storage and transport range is -40 to +85 °C. Shock resistance per EN 60068-2-27 at 250 m/s², vibration at 30 m/s². Supports up to 4 external antennas via RP-TNC connectors, with cable runs from 1 m to 40 m. The 6-LED row display gives basic status at a glance — link, activity, and fault — without needing a screen.
Lifecycle and sourcing posture
For a BOM line or a line-down replacement, this reader is sourced to order against an RFQ. No official successor has been announced, so the 6GT2811-6AB20-2AA0 is the current production variant for the 920-925 MHz UHF band in the RF600 family.
