The Siemens 6GT2898-3AA00 is a SIMATIC RF600 spacer designed to mount transponders measuring 120 mm x 30 mm, with a specified 8.5 mm distance to metal. It's a mechanical support bracket, not an electronic component — its job is to hold the RFID tag at the correct standoff from a metal surface so the read range stays consistent. The spacer is made from PA 12 (polyamide 12) in anthracite, sized 130 mm deep, 31.5 mm wide, and 12 mm high. It's fastened using two M4 screws through the support and into the transponder.
This spacer belongs to the SIMATIC RF600 family, Siemens' industrial RFID system for logistics, production, and assembly lines. The RF622T transponder it supports is a robust tag for metal environments — think pallet tracking, tool identification, or work-in-progress carriers on a conveyor. The 8.5 mm air gap is what keeps the tag readable when mounted directly on a metal part.
Sourcing note
This is a mechanical accessory, not a high-turnover consumable. The minimum order quantity is 10 units. If you're filling a BOM line for a new RF622T installation or replacing a damaged spacer, this is the exact Siemens order code. No functional substitute exists — the 6EP1336-3BA00 is a power supply, not a spacer, so it won't drop into the same panel location or serve the same purpose.
