What this tag is and where it goes
The Siemens 6GT2810-2HG80 is a SIMATIC RF680T UHF RFID transponder built for the RF600 system. It operates across 865 to 928 MHz, covering global UHF bands, and uses the NXP G2XM chip with EPCglobal Class 1 Gen 2 / ISO 18000-63 protocol. The tag is designed for asset tracking and identification in environments where standard tags fail — think paint-shop conveyors, engine-block carriers, autoclave cycles, or foundry work-in-progress where the tag must survive both the process heat and high-pressure washdown.
What the ratings mean for fit
The IP68/IPx9K rating means the tag body withstands continuous immersion beyond 1 m and high-pressure, high-temperature washdown — the same standard used in food-processing and chemical plants. The tag is also IECEx and ATEX certified (II 2G Ex ib IIB T6 to T2 Gb, II 2D Ex ib IIIB T135 °C Db), so it can be mounted in Zone 1 gas and Zone 21 dust hazardous areas without an additional enclosure. The temperature endurance is the headline spec for this part. It operates continuously at 140 °C, survives 5000 hours or 3000 cycles at 200 °C, and 2000 hours or 1500 cycles at 220 °C. Outside the read/write area it can sit at -40 to +220 °C. That thermal profile is what separates the RF680T from commodity UHF tags — it is sized for a paint oven or a hot-metal handling line, not a warehouse pallet rack. Read range is listed as up to 4 m, but that figure is reader-dependent and the system manual notes overrange is possible. In practice, range depends on the RF600 reader model, antenna gain, and mounting surface (metal vs plastic). The tag is multitag-capable and supports a max transfer rate of 320 kbit/s, which matters when you are reading a rack of parts in motion. Memory is organized as 96-bit (12-byte) EPC, expandable to 240-bit (30-byte), plus 64 bytes of user memory and a 64-bit TID. The user memory is lockable, write-protected, and password-protectable — useful for writing a serial number or process step that cannot be overwritten on the line.
Lifecycle and sourcing reality
The lifecycle stage is marked as mature, which in Siemens terms means the product is established and in steady-state supply — no imminent phase-out or last-time-buy announced. The tag carries cULus approval and IECEx certification, so it is accepted in North American and international hazardous-location installations. This is a quoted-to-order line; we source it against an RFQ for the required quantity.
Mounting and mechanical constraints
The tag measures 130 mm deep by 32 mm wide by 15 mm high, in a black PPS (polyphenylene sulfide) housing. It fastens with two M6 screws. The material is silicone-free, which matters in paint shops where silicone contamination causes fisheyes. Shock resistance is rated to 1000 m/s² per DIN EN 60721-3-7 Class 7M3, and vibrational acceleration to 200 m/s². Note that torsion and bending stress are not permissible — the tag must be mounted on a flat surface without flexing.
