What this antenna is and what it does
The Siemens 6GT2812-1EA01 is an RF620A UHF RFID antenna for the SIMATIC RF600 system, operating in the 902 to 928 MHz frequency band — the FCC allocation for the US market. It uses linear polarization and presents a 50 Ω impedance with a maximum VSWR of 2, which keeps reflected power low enough for reliable read ranges in warehouse and logistics gates. The housing is PA 12 (pastel turquoise), sealed to IP67, so it handles washdown environments and outdoor mounting without a secondary enclosure. The operating range is -20 to +70 °C, storage and transport from -40 to +85 °C. It ships with a 0.3 m antenna cable terminated in an RP-TNC male connector. For longer runs, accessory cables from 1 to 40 m are available. Mounting is via two M5 screws; the antenna measures 75 mm wide by 75 mm high by 20 mm deep.
Fit and integration notes
This antenna is designed for the SIMATIC RF600 reader family. The RP-TNC connection is standard for UHF RFID antennas in this class. The 105° vertical and 130° horizontal beam angles give a broad read zone typical for dock-door or conveyor applications — not a narrow spot beam for targeted single-tag reads. IP67 means the antenna body and the connector interface are protected against dust ingress and temporary immersion. In a food or beverage line with scheduled washdown, no additional gland or boot is needed at the antenna end — just ensure the RP-TNC mating connector is also rated for the environment. The antenna is silicon-free, which matters for paint-shop or potting applications where silicone outgassing can cause adhesion failures.
Lifecycle and sourcing
For a BOM line that specifies 6GT2812-1EA01, the fit is confirmed by the frequency band (902-928 MHz, US FCC), the RP-TNC interface, and the SIMATIC RF600 compatibility. If the customer's approved vendor list requires a specific antenna for the RF600 reader, this is the direct Siemens order code.
