The Siemens 6GT2810-3HG80 is a SIMATIC RF682T UHF RFID tag built for the RF600 reader system. It operates across 868 to 928 MHz using the EPCglobal Class 1 Gen 2 / ISO 18000-63 protocol, with a maximum transfer rate of 320 kbit/s. The tag is designed for tracking assets that see high temperature cycles — think paint ovens, sterilization tunnels, or engine test cells — where a standard label would fail within hours. The housing is black PPS (polyphenylene sulfide), 130 x 32 x 15 mm, fastened with two M6 screws. It carries an NXP UCODE DNA chip with 384 bytes of user memory and 96-bit EPC memory expandable to 224 bits. The tag is multitag-capable, meaning multiple tags can be read in the same field without collision.
The IP68/IPx9K protection class means this tag survives both continuous immersion and high-pressure washdown. Temperature tolerance is the headline differentiator. The tag survives storage from -40 to +100 °C, operates during read/write access from -25 to +100 °C, and can endure outside the read/write area from -40 to +220 °C. That 220 °C survival — tested for 250 hours or 500 cycles — is what qualifies it for paint-cure ovens and autoclave cycles. Operating temperature is permanent up to 140 °C. The 3.5 m maximum read range is reader-dependent per Siemens application note; overrange is possible. Shock resistance is tested to 1000 m/s² and vibration to 200 m/s², both per DIN EN 60721-3-7 Class 7M3. That is the equivalent of a 100 g shock — enough for conveyor impact or robotic end-of-arm tooling. Torsion and bending stress are explicitly not permitted, so the mounting screws must pull the tag flat against a rigid surface. MTBF is listed at 1940 years. That is a calculated figure under controlled conditions, not a field warranty.
