What it is and where it fits
The Siemens 6GT2898-5AB00 is a retaining bracket from the SIMATIC RF600 family, purpose-made for RF645T transponders. It holds the transponder crosswise in the bracket, which sets the read orientation relative to the antenna. The part is molded from PA 6.6 GF — glass-fiber-reinforced nylon — in black, sized at 66 mm wide, 24 mm deep, and 15.3 mm tall.
Integration note
The bracket's 24 mm depth and 66 mm width mean it sits flat against a panel or mounting plate, with the transponder lying crosswise inside. No DIN-rail clip or snap-on feature is listed, so plan for screw or adhesive fixing. The PA 6.6 GF material handles the full temperature range of -40 to +85 °C during operation, storage, and transport — no derating needed for cold storage or hot enclosure air.
