The Siemens 6GT2701-5CA02 is a SIMATIC RTLS anchor, model RTLS4430A, part of the RTLS4400 system using Chirp technology. It's a fixed reference node in a real-time locating system, not a mobile tag — it listens for tag chirps and reports them to the locating engine. Rated range hits 1000 m in open-air applications, with a typical localization accuracy of 1.5 m. The radio uses IEEE 802.15.4a CSS at up to 1000 kbit/s over a mesh network. One digital output, powered over 8 to 30 V DC (24 V nominal draws 0.21 A, max 100 mW). The housing is IP65-rated ASA+PC in Ti gray, 180 x 180 x 48 mm, fastened with 3 M4 screws. Three LEDs give visual status.
The anchor is designed for fixed installation in industrial environments — on walls, ceilings, or structural steel. The IP65 rating means it handles dust and water jets, so it can be mounted in washdown areas or outdoors under cover. A corner mount bracket and ceiling suspension plate are included accessories. Power and I/O connect via a Bulgin PX0412/03P 3-pin connector. The housing is silicon-free, important for paint-shop or potting applications where silicone contamination is a concern.
This anchor is classified as mature — meaning it's in steady production, not newly introduced and not on a phase-out path. For a BOM-critical RTLS anchor that backs up a production line, that's the right lifecycle stage: stable supply, no imminent LTB. If you're holding a spare for a legacy RTLS4400 installation, this is the direct drop-in — same Chirp protocol, same mechanical footprint, same connector.
