The Siemens 6GT2810-2AG84-0AX0 is a SIMATIC RF682L SmartLabel, a heat-resistant UHF RFID tag built for industrial asset tracking and work-in-process identification on the RF600 system. It operates across 860 to 960 MHz, covering global UHF bands including ETSI (865-868 MHz) and FCC (902-928 MHz) without a regional variant swap. The tag is a paper laminate, 156 by 40 by 0.4 mm, with a linear-polarized antenna and an NXP UCODE 7xm-2k chip. It supports the EPCglobal Class 1 Gen 2 and ISO 18000-63 protocols, which means it works with any standard UHF reader that speaks those protocols — no proprietary lock-in. Memory is organized as EPC memory expandable up to 448 bits (56 bytes), user memory of 2048 bits (256 bytes), and a 96-bit TID. The chip supports lock, unlock, kill, write protection, and password protection — enough for write-once or re-writable workflows depending on how you configure the access passwords.
Thermal tolerance — the main event
What sets this tag apart is its heat resistance. Outside the read/write area it survives -40 to +230 °C, and during read/write access it operates from -25 to +85 °C. For operation, it tolerates permanent exposure up to 85 °C, six hours at 200 °C, one hour at 220 °C, and short-term peaks to 230 °C. That makes it suitable for tracking parts through paint ovens, curing cycles, or sterilization processes where standard polyimide tags delaminate. The tag is silicon-free and printable via thermal transfer, so you can add barcodes or human-readable text that survive the same thermal exposure. Fastening is by gluing or screwing — no rivet holes, no mechanical interlock needed.
Read range and deployment context
Maximum read range is 6 meters, but the evidence notes this is reader-dependent and overrange is possible — the system manual (RF600) gives the actual achievable distance with your specific reader and antenna setup. The tag is multitag-capable, so it works in dense-read environments like pallet portals or conveyor chutes. IP67 means the tag body and antenna survive washdown, dust, and temporary immersion — suitable for food-and-bev lines, chemical processing, or outdoor logistics yards. The paper substrate is not waterproof indefinitely, but the encapsulation provides the IP rating during normal use.
No official successor is listed. If you need a drop-in replacement for an existing BOM line, the 6GT2810-2AG84-0AX0 is the current mature version — no last-time-buy window to manage.
