The Siemens 6GT2810-2AG84-0AX1 is a SIMATIC RF682L SmartLabel — a UHF RFID tag built on a Nomex paper substrate, sized 156 x 40 x 0.4 mm and beige in color. It operates across the full 860 to 960 MHz UHF band and uses an NXP UCODE 7xm-2k transponder chip with EPCglobal Class 1 Gen 2 / ISO 18000-63 protocol. The tag is IP67 rated, meaning the entire assembly — including the antenna and chip — withstands dust ingress and temporary immersion, so it survives washdown environments in automotive paint shops or industrial laundries.
The operating temperature range outside the read/write area spans -40 to +230 °C, with permanent operation up to 85 °C, 6 hours at 200 °C, 1 hour at 220 °C, and short-term peaks to 230 °C. This makes the tag suitable for tracking assets through paint curing ovens or powder-coating lines where standard plastic tags would fail. During read/write access the tag works from -25 to +85 °C, which covers most production-floor environments. The Nomex paper substrate is silicon-free and printable via thermal transfer — critical for paint-shop applications where silicone contamination causes adhesion failure in downstream coating processes. Memory is organized as 96-bit (12-byte) EPC memory expandable to 448-bit (56-byte), plus 2048-bit (256-byte) user memory and 96-bit (12-byte) TID memory. The tag supports lock, unlock, kill, write protection, and password protection on the memory. Maximum transfer rate is 320 kbit/s, and the read range reaches up to 6 m depending on the reader — though the system manual notes overrange is possible and range is reader-dependent. The tag is multitag-capable, so multiple tags can be read in the field simultaneously. It has no backup battery — it's a passive UHF tag powered entirely by the reader's interrogation signal.
Deployment and mounting
The tag can be fastened by gluing or screwing — the 0.4 mm thickness and paper substrate mean it conforms to curved surfaces but is not designed for repeated flexing; torsion and bending stress are only conditionally permissible. It's intended for the SIMATIC RF600 system and is suitable for paint-shop customer versions. The 156 x 40 mm footprint is large enough for custom printing of barcodes or human-readable labels via thermal transfer, which can be applied before or after the tag is mounted.
