The Siemens 6GT2700-8CF02 is a SIMATIC RTLS transponder OEM PCB — a bare-board electronics module for the RTLS4000 real-time location system using chirp spread-spectrum technology. It operates in the 2.4 to 2.48 GHz ISM band at a maximum data rate of 1000 kbit/s over the IEEE 802.15.4a CSS protocol. This is the electronics core without enclosure or antenna — it connects to a 17 × 9.5 mm remote antenna via a 5 cm cable and requires a 3.3 V DC supply (±100 mV, max 0.2 A) through a JST SM04B-SRSS-TB connector. Configuration memory is stored on internal FLASH. Range reaches 1000 m in open-air applications (always follow the manual for site-specific conditions). The board measures 44 mm wide, 24 mm deep, and just 7.5 mm tall, fastened with three M1.6 screws.
This OEM PCB is designed for embedding into customer equipment — it's not a standalone transponder you mount on a wall. The bare-board form factor (no IP rating beyond IP00) means it goes inside a host device enclosure that provides mechanical and environmental protection. The remote antenna is the only external element.
The 1000 kbit/s data rate is the raw PHY rate; application-layer throughput will be lower due to protocol overhead. Supply tolerance is tight — 3.3 V ±100 mV at up to 0.2 A. That's a regulated 3.3 V rail, not a 24 V industrial supply. The JST SM04B-SRSS-TB connector is a standard 1 mm-pitch crimp housing; verify your cable assembly matches before committing the BOM. No backup battery on board — the FLASH configuration memory retains settings without power, but the transponder is not battery-backed for untethered operation. It needs continuous 3.3 V supply to function.
