What it is and what it's for
The Siemens 6GT2812-0EA01 is a UHF RFID antenna from the SIMATIC RF600 family, model RF615A. It's built for the US FCC band, transmitting from 902 to 928 MHz with linear polarization. The IP67 rating means the antenna body and the internal electronics are sealed against dust and low-pressure water jets — it can handle washdown environments, outdoor mounting, or the splashes you'd see on a conveyor line. Operating temperature runs from -20 to +70 °C, so it's fine for unheated warehouses or refrigerated areas, but not for freezer or high-heat zones.
Mounting and connection
The antenna measures 52 x 52 x 16 mm and mounts via two M4 screws. The housing is PA 6 (nylon), black, and silicon-free — important if the panel or surrounding equipment has strict outgassing specs. It comes with a 0.3 m pigtail terminated in an RP-TNC male connector. The 50 Ω impedance and maximum VSWR of 2:1 are standard for this class; the antenna cables available from 1 to 40 m let you place the reader body away from the antenna if needed.
Sourcing and lifecycle
The 6GT2812-0EA01 is listed as active in the Siemens lifecycle system. No end-of-life notice or successor has been issued — this is a current-production part, not a phase-out item. It's designed for the SIMATIC RF600 reader family, so if you're maintaining or expanding an RF600-based RFID installation, this is the direct drop-in antenna for the US band.
