The Siemens 6GT2701-5CA02-0AX0 is a SIMATIC RTLS Anchor built for the RTLS4400 real-time locating system using Chirp spread-spectrum technology. It's the fixed-position node in a mesh network that tracks tags across a defined area — think warehouse zones, production aisles, or outdoor laydown yards where you need to know where a pallet or a piece of work-in-progress is within a meter or two. Range is rated at 1000 m in open-air conditions, with a typical localization accuracy of 1.5 m. That 1000 m figure is the free-air maximum; the manual is the final authority for your specific environment. The radio operates in the 2.4 GHz ISM band using IEEE 802.15.4a CSS at up to 1000 kbit/s, so it's compatible with the Chirp protocol infrastructure. The enclosure is IP65-rated, made from ASA+PC in Ti gray, and it's silicon-free — important for paint-shop or coating-line environments where silicone contamination ruins adhesion. It draws 0.21 A at 24 VDC nominal (8 to 30 VDC range), consuming 100 mW maximum. Power and I/O connect through a Bulgin PX0412/03P 3-pin connector; there's one digital output, no digital inputs.
Mounting and environmental range
Mounts with three M4 screws, and the package includes a corner mount bracket and a mounting plate for ceiling suspension. Dimensions are 180 mm wide by 180 mm deep by 48 mm high — a compact footprint for a ceiling or wall mount in an industrial bay. Operating, storage, and transport temperature all span -40 to +60 °C, so it handles unheated warehouses and frozen transport without derating.
