On-Metal UHF Tag for Harsh Environments
The Siemens 6GT2810-2DC00 is a SIMATIC RF640T Tool Tag — an on-metal UHF transponder built for direct mounting on conductive surfaces where standard tags detune and fail. It operates in the 865-868 MHz ETSI band and communicates via the EPCglobal Class 1 Gen 2 / ISO 18000-63 protocol, making it interoperable with any standard UHF reader that supports that air interface.
Read Range and Memory Configuration
Maximum read range is 4 m, but this is reader-dependent — the system manual notes that overrange is possible, and actual performance depends on the reader model, antenna gain, and installation environment. For a reliable estimate, consult the RF600 system manual or the application note at the Siemens support portal. The tag uses an NXP G2XM chip with 240-bit EPC memory (expandable from a 96-bit sequential identifier) and 64 bytes of user memory. The memory supports lock, unlock, write protection, and password protection. The TID memory is 64 bits. Data transfer rate over the air is up to 320 kbit/s. The tag is multitag-capable, meaning multiple tags in the read field can be inventoried in a single session — standard for Gen2 anti-collision. It has no backup battery; it is a passive transponder powered entirely by the reader's RF field.
Operating temperature during read/write access is -25 to +85 °C; outside the read/write area the tag survives -40 to +125 °C. Storage range is the same -40 to +125 °C. Shock resistance is 1000 m/s² per DIN EN 60721-3-7 class 7M3; vibrational acceleration is 200 m/s². The MTBF is listed at 1757 years. The tag is silicon-free and not printable. Polarization is linear. The material is PA12, which offers good chemical resistance for industrial lubricants and coolants.
