What it is and what it does
The Siemens SIMATIC RTLS4330A anchor (order code 6GT2701-5EA03) is a fixed-position node in a real-time locating system, using UWB and Chirp spread-spectrum radio to track assets or personnel within a defined area. It communicates over a MESH network using IEEE 802.15.4-2011 UWB and IEEE 802.15.4a CSS protocols, operating in the 3100–7000 MHz and 2400–2480 MHz bands. The anchor is designed for use with the RTLS4300 system, providing location data with a typical accuracy of 0.2 m on the UWB band and 1.5 m on the Chirp band. Maximum open-air range is 30 m for UWB and 1000 m for Chirp, though actual performance depends on installation conditions and the manual should be followed.
Key ratings and what they mean for fit
The IP65 rating means the anchor is dust-tight and protected against low-pressure water jets from any direction — suitable for washdown areas, outdoor enclosures, or dusty production floors. The housing is ASA+PC plastic in Ti gray, and the unit is silicon-free, which matters for paint-shop or potting applications where silicone contamination is a concern. Supply voltage is 10–30 VDC, with a rated value of 24 VDC, and the maximum current draw is 0.3 A. That means a standard 24 VDC industrial power supply can run multiple anchors on one branch, but the total load on the supply must account for the 0.3 A per unit. The single digital output (sinking, at the same connector) can drive a small indicator or relay for local status. The anchor mounts with three M4 screws and measures 180 mm wide by 180 mm deep by 48 mm high — a compact, square footprint that fits on walls, columns, or ceiling grids. The included corner mount bracket and ceiling suspension plate give flexibility for positioning in a production cell or warehouse aisle.
Where it is used
This class of part — a UWB/Chirp anchor — is deployed in indoor industrial environments for real-time location of assets (tools, AGVs, work-in-progress) or personnel (safety zone monitoring, workflow tracking). The 0.2 m UWB accuracy is tight enough to distinguish which workstation a cart is at, while the Chirp band's longer range (1000 m) can cover a large warehouse with fewer anchors, albeit at lower precision.
