What it is and where it fits
The Siemens 6GT2810-2AC00 is a SIMATIC RF640L SmartLabel PET — a UHF RFID tag designed for the RF600 system. It operates in the 865 to 868 MHz ETSI band and follows the EPCglobal Class 1 Gen 2 / ISO 18000-63 protocol. The tag uses an Alien Higgs 3 chip and offers 96-bit EPC memory expandable to 480 bits, plus 64 bytes of user memory. It is rated IP67, meaning the tag body and antenna survive washdown environments — suitable for production lines where labels see moisture or dust.
Physical and mounting details
Dimensions are 50 mm wide, 22.5 mm deep, and 1.6 mm thick. The top side material is PET, and the tag is one-side adhesible for surface mounting. It is printable via thermal transfer process. Color is white. The tag is silicon-free and conditionally permissible under torsion and bending stress — per the system manual, overrange is possible and range depends on the reader.
Memory and data handling
Memory type is EEPROM. The tag supports lock, unlock, kill, write protection, and password protection. EPC memory starts at 96 bits (12 bytes) and can be expanded up to 480 bits (60 bytes). User memory is 512 bits (64 bytes) but reduces to 128 bits (16 bytes) when EPC memory is at maximum. TID memory is 96 bits (12 bytes). Maximum transfer rate is 320 kbit/s. The tag is multitag-capable and has no backup battery.
