The Siemens 6GT2812-2EA00 is an RF622A UHF antenna for the SIMATIC RF600 system, operating in the 865 to 868 MHz ETSI band with linear polarization and a 50 Ω impedance. It's built for the EU frequency allocation and carries an IP65 rating, so it handles washdown and outdoor exposure in logistics gates, conveyor portals, and warehouse dock applications. The antenna has a 0.3 m integral cable terminated with an RP-TNC male connector, and the housing is Pocan plastic in Ti gray, fastened with two M5 screws.
The 865 to 868 MHz transmit frequency is the ETSI 3-band UHF RFID allocation used across Europe, so this antenna is the correct choice for EU-based installations — it won't work on the FCC 902-928 MHz band. The operating temperature range of -20 to +70 °C covers unheated warehouses and refrigerated logistics areas; storage and transport tolerance extends to -40 to +85 °C. Maximum VSWR of 2 and linear radiation pattern with -5 dB at the beam edges (75° vertical, 100° horizontal) mean the antenna delivers a broad, consistent read zone for pallet- or case-level tagging at typical portal distances. The 50 Ω impedance matches standard UHF RFID reader outputs; the RP-TNC connector is the common interface on Siemens RF600 readers and most industrial UHF RFID systems.
