The Siemens 6GT2790-0BE20 is a SIMATIC RTLS accessory holder — a PVC plate, 200 x 277 x 5 mm in grey, designed specifically for mounting an RTLS4030A/G gateway or anchor to a wall or ceiling. It ships with the fixing screws included.
Sourcing and Lifecycle Reality
This part carries a lifecycle status of NRND (Not Recommended for New Designs), with the product status marked as mature. That means Siemens is no longer actively promoting it for new installations, though it remains available through distribution channels for existing deployed systems. If you're maintaining a live RTLS4030A/G installation, this is the correct holder — but for a new build, verify with your Siemens contact whether the RTLS4x30G/A platform or its mounting accessories have been superseded.
What the Ratings Mean for Fit
The plate dimensions — 200 mm wide, 277 mm deep, and just 5 mm thick — match the footprint of the RTLS4030A/G anchor, so it's a direct bolt-on. The PVC material is lightweight and non-conductive, appropriate for indoor ceiling suspension where the anchor needs a stable, non-metallic mounting surface. The operating and storage temperature range of -40 to +70 °C covers most conditioned indoor environments and unheated storage areas.
Deployment Context
This holder is strictly for the RTLS4030A/G gateway or anchor — it won't fit other RTLS hardware without modification. The wall-mount or ceiling-suspend design means you'll need to provide your own anchors for the building structure; the kit includes only the screws that fasten the gateway to the plate. For a clean install, pre-drill the mounting surface and use M4 or equivalent hardware suited to the ceiling material.
