The Siemens 6GT2700-8AF03 is a SIMATIC RTLS transponder — a PCB OEM pulse UWB tag for the RTLS4000 real-time locating system. It operates in the 3100 to 7000 MHz UWB band per IEEE 802.15.4-2011, with a maximum transfer rate of 6800 kbit/s and an open-air range up to 30 m (range figures assume clear line-of-sight; always follow the installation manual for your environment). This is an OEM-level component — a bare PCB with an LED display and FLASH configuration memory, supplied in packs of 10 units. It requires a 3.3 V supply (±100 mV) drawing up to 0.3 A via a JST SM04B-SRSS-TB connector, and connects to a 20 x 38 mm remote antenna via a 5 cm cable. There is no backup battery.
The board measures 44 mm wide, 24 mm deep, and just 7.5 mm tall — a low-profile footprint that fits inside an OEM enclosure or on a machine sub-panel. It is fastened with three M1.6 screws; no DIN-rail clip is provided. The IP00 rating means it is not protected against dust or moisture ingress, so it must be housed inside a sealed enclosure in any production environment. Operating temperature range is 0 to 50 °C during read/write access and outside the read/write area; storage range is also 0 to 50 °C. This is a controlled-environment part — not rated for outdoor or washdown zones.
Sourcing this part is a straightforward RFQ — no last-time-buy urgency, no broker scavenger hunt. The 10-unit pack quantity is the standard delivery unit.
What the Headline Ratings Mean for Your Decision
The 30 m open-air range is the maximum under ideal conditions — real-world performance in a factory with metal racks, machinery, and RF interference will be lower. The 6800 kbit/s data rate is the raw PHY rate; actual throughput depends on tag density and anchor configuration in the RTLS4000 system. The 3.3 V supply tolerance of ±100 mV is tight — a standard 3.3 V rail from a switching regulator with 1% accuracy is fine, but a poorly regulated supply or long cable drops could push the tag out of spec. The JST connector is a specific mating part; plan for that in your cable harness design.
