The Siemens 6GT2790-0DE00 is a clip bracket for the SIMATIC RTLS family — specifically designed to mount RTLS4083T and RTLS4040T transponders to a machine frame, conveyor rail, or panel wall. It's a mechanical accessory, not an electronic module: no wiring, no backplane bus, no configuration needed. The bracket measures 51.5 x 67.4 x 18.1 mm and is molded from a nylon-12 derivative (P12/Vestamid X7166) in Ti gray, which is the standard industrial color for Siemens RTLS hardware. Mounting requires four screws (max 3.5 mm diameter) with washers — not included — and the installation note warns to keep the screw head from damaging the transponder body. The bracket itself is rated for storage, transport, and operation across -10 to +55 °C, so it's fine for most indoor factory environments but not for freezer or outdoor extremes.
What This Bracket Does (and Doesn't Do)
This is a pure mechanical mount — it holds the transponder in position so the RTLS system reads its location reliably. It doesn't add any electrical interface, antenna gain, or environmental sealing beyond what the transponder itself provides. The plastic material is a glass-reinforced nylon (Vestamid X7166), which offers decent impact resistance and chemical resistance to oils and coolants typical on a production floor. If you're retrofitting an existing RTLS4083T or RTLS4040T that was previously taped or zip-tied, this bracket gives you a proper screw-down installation that won't drift out of alignment.
