The Siemens 6GT2701-5CA03 is a SIMATIC RTLS Anchor RTLS4430A — a fixed-position reference node in a real-time locating system using Chirp Spread Spectrum (CSS) technology per IEEE 802.15.4a CSS. It operates in the 2400…2480 MHz ISM band and forms a MESH Network with other anchors and tags for self-healing coverage across a facility. Rated for a 1000 m open-air range, this anchor provides room-level localization with a typical accuracy of 1.5 m. The IP65-rated housing (ASA+PC, Ti gray) withstands dust ingress and water jets, making it suitable for deployment on production floors, warehouses, or outdoor logistics yards where washdown or exposure to the elements is expected. Power is supplied at 24 V DC (nominal, with an 8…30 V DC range) via a Bulgin PX0412/03P 3-pin connector, drawing a maximum of 0.21 A. The same connector type is used for the single digital output. A three-LED display provides on-device status indication.
The 1000 m open-air range is the maximum line-of-sight distance between this anchor and a tag. In practice, building materials, racking, and interference reduce that; the manual should be consulted for indoor range estimates. The 1.5 m typical accuracy means this anchor is suited for zone-level asset tracking (which bay, which aisle) rather than sub-meter positioning. The -40…+60 °C operating range covers cold storage and hot factory environments alike. The 8…30 V DC input range gives flexibility: it runs on a standard 24 V industrial supply but tolerates drops to 8 V (e.g., long cable runs) and surges to 30 V without damage. The 0.21 A max draw is modest — a 24 VDC, 0.5 A supply can power two anchors with headroom.
This anchor is a component of the SIMATIC RTLS4400 system, which tracks assets, tools, or personnel in industrial environments. Typical deployments include automotive assembly lines tracking work-in-progress, warehouse forklift location, or hospital equipment tracking. The MESH networking means anchors relay data through each other, reducing the need for wired backhaul to every node.
