The Siemens 6GT2811-5BA00-0AA0 is a SIMATIC RF620R ETSI UHF RFID reader from the RF600 system family, designed for reading and writing passive transponders compliant with EPCglobal Class 1 Gen 2 and ISO 18000-6C protocols. It operates in the 865-868 MHz ETSI band with a typical read range of 5 m, extendable per the RF600 system manual, and communicates via an RS422 interface through an 8-pin M12 connector. The reader is intended for fixed-mount industrial identification applications — think conveyor-based asset tracking, work-in-progress monitoring, or tool identification in automotive assembly — where a rugged IP65 housing and a wide -25 to +55 °C operating range are needed. Power is supplied at 24 VDC nominal (21.6 to 30 V range), drawing 0.395 A typical and 0.47 A maximum, with a minimum power consumption of 65 mW. The housing is aluminum with ABS (GF20) construction, finished in silver/pastel turquoise, and is declared silicon-free — relevant for paint-shop or coating-line environments where silicone contamination is a concern.
Mounting is via 4 x M6 screws or VESA 100 pattern with 4 x M4 screws. Dimensions are 252 mm high, 193 mm wide, 52 mm deep. The reader connects to SIMATIC communication modules over the RS422 interface for TIA Portal integration. The 3-color LED display gives local status indication.
