The Siemens 6GT2890-0AA00 is a mounting kit with a jointed arm designed for flexible positioning of antennas in the SIMATIC RF600 family. It accepts products with VESA 100 or VESA 75 mounting hole patterns, which covers most standard RF600 readers and antennas — the explicit exceptions are the RF620A and RF615A, which are not compatible. The assembly measures 143 mm deep, 100 mm wide, and 100 mm tall, so it fits within a standard enclosure footprint without requiring extra panel depth.
Deployment context
This arm lets you orient an antenna in three axes for optimal read zone coverage on a conveyor or portal. The VESA pattern means it bolts directly to the back of compatible readers without an adapter plate. Panel builders will appreciate the 100 mm × 100 mm base — it occupies about the same footprint as a standard VESA display mount, so layout on a sub-panel or machine frame is straightforward.
