The Siemens 6GT2700-5DC15 is a SIMATIC RTLS4083T plus transponder — a battery-powered UWB tag with a 2.7" ePaper display (296 x 128 pixels) and a single function key, designed for real-time locating systems using UWB and phase technology. It operates in the 2.4 GHz and 3.1–7.0 GHz bands depending on country approvals, using IEEE 802.15.4 and IEEE 802.15.4-2015 HRP UWB protocols, giving it a typical open-air range of 30 m and a maximum of 50 m. The IP65-rated housing (Ti gray, PC material, 95 x 64.6 x 13.8 mm) is designed for industrial environments — the tag can be mounted with cable ties or clips and withstands washdown conditions.
Power and battery life — the real constraint
Power comes from a rechargeable Li-ion battery via charging contacts. Battery life depends heavily on update rate: 1 year in standby, 6 months with UWB localization at 1-second cycles, but only 25 days with display updates every 10 seconds. The battery is not user-replaceable, and the tag includes a backup battery component. This means the tag has a finite service life — plan for replacement rather than field battery swaps.
Memory and display capability
The transponder stores 5 background images, 20 fonts, and 20 text fields (58 characters each) in FLASH configuration memory. The ePaper display updates only when content changes, which is what enables the multi-year standby battery life.
Lifecycle reality — NRND, source now
This part is classified as NRND (Not Recommended for New Designs). It remains available for existing BOM lines and maintenance spares, but new projects should evaluate the current RTLS4000 portfolio for a replacement.
What it fits — system and environment
The 6GT2700-5DC15 is built for the SIMATIC RTLS4000 system using UWB with phase technology. It is not a standalone Bluetooth or Wi-Fi tag — it requires the RTLS4000 infrastructure (anchors and software) to function. Operating temperature for the display is 0 to 40 °C; outside the read/write area and during storage, the tag tolerates -10 to +50 °C. The silicon-free construction suits clean-room or paint-shop environments where outgassing is a concern.
