What it is and what it does
The Siemens 6GT2810-2AE81-0AX2 is a SIMATIC RF630L SmartLabel — a PET-based, one-side-adhesible RFID tag designed for the RF600 system. It operates across the full UHF band from 860 to 960 MHz, which covers global regulatory regions (EU, US, Asia) without needing region-specific variants. The NXP G2iL chip inside gives you 128-bit EPC memory and 16 bytes of user memory, with lock, unlock, kill, write protection, and password protection features. Read range reaches up to 4 m, though that's reader-dependent — the system manual (RF600) covers overrange conditions.
Where it goes and how it mounts
This is a label-form-factor tag, 80 mm deep by 26 mm wide, with a PET substrate that's printable via thermal transfer. It's one-side adhesible — peel and stick onto plastic surfaces. The IP67 rating only holds when properly adhered; if the edge lifts, the seal breaks. It's designed for the RF600 reader family, and it's multitag-capable, so you can read multiple tags in the field simultaneously. The tag handles torsion and bending stress conditionally — it's not a ruggedized industrial mount, but it's fine for flat or gently curved surfaces.
Environmental limits worth knowing
Operating temperature during read/write access is -25 to +85 °C. Outside the read/write area, it survives -40 to +120 °C. Storage is tighter: 5 to 25 °C, with a maximum shelf life of 2 years at 45% to 55% humidity. The transient rating (-40 °C to 120 °C for 90 minutes) covers sterilization or paint-oven passes, not continuous exposure. No backup battery — it's passive, powered by the reader's field.
