The Siemens 6GT2890-2AA00 is a stainless steel mounting bracket from the SIMATIC RF600 family, designed to secure RF680T and RF682T transponders in high-temperature zones. Two brackets provide the support for mounting each transponder, and the minimum order quantity is 20 units (one set contains 2 units, so 20 units in total). The bracket's material — stainless steel — and its full temperature range of -40 to +220 °C across storage, operation, and transport mean it can live in the hot zone of a production line without degrading. That -40 °C floor also covers cold-chain or outdoor staging areas. The metallic finish is the as-manufactured surface, not a coating.
Dimensions and fit
At 40.5 mm wide, 25 mm deep, and 12.5 mm tall, this bracket is compact enough to fit into tight enclosures or alongside existing RFID reader mounts. The footprint is small enough that two brackets per transponder won't crowd a panel backplate or a machine frame.
Because the part is active and the MOQ is 20 units, a sourcing buyer should quote against an RFQ to lock in the batch quantity and lead time. The stainless steel construction and high-temperature rating make it a dedicated fit for the RF680T/RF682T — not a generic bracket that can be swapped with a different Siemens accessory without verifying the transponder interface.
