It operates across 865 to 928 MHz, covering the global UHF bands for EPCglobal Class 1 Gen 2 and ISO 18000-63 protocols. The tag is designed for direct-on-metal mounting — the PPS housing and internal antenna tuning handle the detuning that kills standard tags on metal surfaces. Read range is up to 5 m, though the system manual notes this is reader-dependent; overrange is possible with appropriate readers. That 5 m figure assumes a clean air path and an RF600-series interrogator — real-world range on a metal conveyor frame or machine tool will vary with the reader's output power and antenna gain. The tag carries an NXP G2XM chip with 96-bit (12-byte) EPC memory expandable to 240 bit (30 byte), plus 512-bit (64-byte) user memory and 64-bit TID memory. Memory is EEPROM with lock, unlock, write-protection, and password-protection features. Transfer rate hits 320 kbit/s maximum. ## Environmental survival — what the ratings actually mean IP68/IPx9K is the full ingress story: IP68 means dust-tight and continuous immersion beyond 1 m depth (manufacturer-specified conditions), while IPx9K means it withstands high-pressure, high-temperature washdown — steam jets at 80 °C and 100 bar. This tag lives on paint lines, food processing equipment, or outdoor asset tracking where hosing down is routine. Temperature tolerance is the standout: outside the read/write area it survives -40 to +220 °C. During read/write access the range narrows to -25 to +100 °C. For permanent operation it handles 140 °C continuously, and for 5000 hours or 3000 cycles it can take 200 °C, or 2000 hours or 1500 cycles at 220 °C. That covers autoclave cycles, paint curing ovens, and engine-bay proximity. Shock resistance is 1000 m/s² per DIN EN 60721-3-7 Class 7M3; vibration is 200 m/s². The housing is PPS (polyphenylene sulfide), a high-temp engineering thermoplastic, and the tag is silicone-free — important for paint-shop and clean-room applications where silicone outgassing causes defects. ## Mechanical fit and mounting Dimensions are 130 mm long, 32 mm wide, 15 mm tall. Fastening is via two M6 screws through the tag body. The evidence explicitly states torsion and bending stress are not permissible — mount it flat against a rigid surface, not cantilevered or on a flexible bracket. Color is black; no printing is possible on the tag surface, so label or mark the asset separately. MTBF is listed at 1940 years — a calculated figure under controlled conditions, not a field warranty. It reflects the passive, solid-state nature of the tag (no battery, no moving parts), but real-world survival depends on mechanical abuse and thermal cycling, not the MTBF number.","metaTitle":"Siemens 6GT2810-2HG81 SIMATIC RF680T RFID Tag, 865-928 MHz,","metaDescription":"Siemens 6GT2810-2HG81 SIMATIC RF680T on-metal RFID tag. 865-928 MHz, 5 m range, IP68/IPx9K, -40 to +220°C.
