The Siemens 6GT2398-1DD00 is a SIMATIC RF300/RF200 antenna — the ANT 30 — built for 13.56 MHz RFID read/write heads in industrial identification systems. It's a stainless steel V2A cylinder, 30 mm diameter, 40 mm deep, with an M30 x 1.5 thread and two stainless steel nuts for panel mounting. The M8 4-pin female connector mates directly to compatible readers: RF250R, RF350R, or RF350M. IP67 means the body and connector survive washdown and wet environments — a common spec for food, beverage, or outdoor conveyor lines.
The 13.56 MHz operating frequency is the global HF RFID standard — it works with ISO 15693 and ISO 14443 tags, giving read ranges typically up to a few hundred millimetres depending on tag size and reader power. Shock resistance at 500 m/s² and vibration at 200 m/s² mean it holds up on moving machinery or near press lines without losing alignment. The IECEx marking is present on the antenna itself, but the ATEX approval for explosive atmospheres follows the connected reader — so in a hazardous zone, check that the reader carries the zone rating you need.
