- Description
The Siemens 6GT2812-1AA08 is a SIMATIC RF662A circular-polarized UHF RFID antenna for the SIMATIC RF600 reader family, covering 865 to 928 MHz with 7 dB gain and a 56-degree horizontal by 58-degree vertical beamwidth. Housed to IP67 in a 312 x 312 x 68 mm Pocan enclosure with an RP-TNC connector, it operates from -25 degrees C to +75 degrees C.

Selection Notes
The RF662A's 7 dB gain and narrower 56 by 58 degree beamwidth focus energy into a longer, tighter read corridor than a wide-angle antenna in the family, so it fits dock-door or aisle portals where read range matters more than side coverage. Its IP67 rating and larger 312 x 312 mm aperture make it the pick over the lower-gain antenna for outdoor or washdown-exposed installations that also need extended range. The RP-TNC connector matches the RF600 reader antenna ports directly, with cable runs up to 40 m.
