What this UHF RFID tag is
The Siemens 6GT2810-2AE81-0AX3 is a SIMATIC RF630L SmartLabel — a white PET UHF RFID tag designed for the RF600 system. It measures 75 mm deep by 20 mm wide by 0.3 mm thick, with one-side adhesive fastening. The tag achieves IP67 protection when properly adhered to a surface, meaning the entire assembly — tag body and adhesive bond — withstands dust ingress and temporary immersion per the standard. This is a field-applied consumable, not a panel-mounted module; you apply it to assets or products that need to be tracked through a read zone.
RF performance and chip details
Operating frequency spans 860 to 930 MHz, covering global UHF bands including ETSI (865-868 MHz) and FCC (902-928 MHz). The tag uses the NXP UCODE 7xm-2K transponder chip, supporting the EPCglobal Class 1 Gen 2 / ISO 18000-63 protocol. Maximum read range is 5 m, but this is reader-dependent — the system manual notes overrange is possible, and actual range varies with the specific RF600 reader model and antenna configuration. The EPC memory is 96 bits (12 bytes), expandable up to 448 bits (56 bytes); user memory is 2048 bits (256 bytes); TID memory is 96 bits (12 bytes). Transfer rate reaches 320 kbit/s maximum. Memory features include lock, unlock, kill, write protection, and password protection via the EEPROM type.
Environmental limits and deployment context
During read/write access, the tag operates from -25 °C to +85 °C. Outside the read/write area, it survives -40 °C to +120 °C. Storage temperature is 5 °C to 25 °C, with a maximum storage life of 2 years at 45% to 55% humidity. Operating temperature is permanent up to 85 °C, with transient exposure to -40 °C to 120 °C for up to 90 minutes. The tag is multitag-capable and has no backup battery. Torsion and bending stress are conditionally permissible — meaning the tag can flex slightly during application but is not designed for repeated mechanical flexing in service. The printing process is thermal transfer, so you can encode variable data (serial numbers, barcodes) onto the white PET surface before application.
