The Siemens 6GT2810-2AE81-0AX0 is a SIMATIC RF630L SmartLabel PET RFID tag — a white, printable, one-side-adhesive label built for the RF600 system. It runs the NXP G2iL chip with 128-bit EPC memory and 16 bytes of user memory, operating across 860 to 960 MHz UHF. The tag is EEPROM-based, supports lock, unlock, kill, write protection, and password protection, and transfers data at up to 320 kbit/s. Read range is up to 4 m, though that's reader-dependent and overrange is possible per the system manual.
Deployment context and environmental limits
This is a label you stick on assets — one-side adhesible, strongly adhesive on plastic per the description. The PET material handles torsion and bending stress conditionally, so it's not for flex zones. IP67 rating applies when properly adhered, meaning the tag and its antenna survive washdown and outdoor exposure. Operating temperature during read/write is -25 to +85 °C; outside the read/write area it tolerates -40 to +160 °C for short periods (90 minutes). Storage life maxes at 2 years at 45-55% humidity, 5-25 °C. That 160 °C peak makes it useful for tracking items through paint ovens or sterilization cycles, but the permanent operating limit is 85 °C.
The 860-960 MHz frequency band covers global UHF RFID allocations (Europe 865-868 MHz, US 902-928 MHz), so this tag works with readers configured for either region. The NXP G2iL chip is a standard Gen2 chip — compatible with most UHF readers that support ISO 18000-6C and EPC Class 1 Gen 2. The 128-bit EPC memory is the standard size for item-level tagging; the 16-byte user memory gives you a small scratchpad for additional data like lot numbers or date codes. The 4 m read range is a maximum — expect less in dense metal environments or when multiple tags are in the field (multitag-capable, but range drops with tag count).
