What it is and what it does
The Siemens 6GT2810-3HG81 is a SIMATIC RF682T RFID transponder designed for the RF600 system. It operates across the full UHF band from 865 to 928 MHz, covering global regulatory regions for passive UHF RFID. The tag uses a UCODE DNA chip with EPC memory expandable from 96 to 240 bits and 384 bytes of user memory.
Where it goes — deployment context
This tag is built for harsh environments. The IP68/IPx9K rating means it survives continuous immersion and high-pressure, high-temperature washdown — think food processing, paint lines, or outdoor asset tracking. The PPS housing and silicone-free construction suit cleanroom and high-temp zones. Operating temperature reaches 220 °C for up to 2000 hours, so it can follow parts through paint ovens or sterilization cycles.
Read range and mounting reality
Maximum read range is 3.5 m, but that's reader-dependent — the system manual (RF600) notes overrange is possible. The tag mounts with two M6 screws and is rated for shock to 1000 m/s² per DIN EN 60721-3-7 Class 7M3. It's an on-metal tag, so it works mounted directly on conductive surfaces without the detuning you'd get from a standard label. No backup battery — it's fully passive, powered by the reader field.
Lifecycle and sourcing
Status is active per Siemens lifecycle classification. This is a current-production part, not a phase-out or NRND line. The 1940-year MTBF figure reflects the solid-state passive design — no moving parts, no battery to fail. For BOM freeze or new builds, this tag is a standard, stocked line item in the SIMATIC RF600 family.
