The Siemens 6GT2810-0DC00 is a SIMATIC RF640T Tool Tag — an on-metal RFID transponder designed for industrial asset tracking. It operates at 868 MHz (ETSI) using the ISO 18000-6B standard with an NXP UCODE HSL chip, providing 216 bytes of user memory. The 50x8 mm (DxH) cylindrical housing is rated IP68, meaning it survives continuous immersion and washdown environments common in automotive or heavy-machinery tool cribs.
The 868 MHz (ETSI) frequency band means this tag is approved for European Union operation — not for North American 902-928 MHz readers. The on-metal transponder design (RF640T series) means it mounts directly on metallic surfaces without the detuning that kills standard RFID tags; the 50x8 mm cylindrical form factor fits standard tool-holder bores or drill-chuck slots. IP68-rated housing withstands washdown, coolant mist, and immersion to 1 meter for 30 minutes — typical for tool-presence detection in CNC machining cells. The 216-byte user memory stores tool ID, calibration data, or cycle counts. The NXP UCODE HSL chip supports the ISO 18000-6B protocol, which is a simpler, read-dominant standard compared to 6C — verify your reader infrastructure supports 6B before committing.
