What this tag is and where it fits
The Siemens 6GT2810-2AC82 is a SIMATIC RF630L SmartLabel — a passive UHF RFID tag built on a PET substrate, sized 45x20 mm, and designed for industrial asset tracking through the RF600 reader system. It's a consumable tag, not a module: you apply it to plastic or foil surfaces via the one-side adhesive backing, and it carries no battery. The Alien Higgs 4 chip inside runs EPCglobal Class 1 Gen 2 / ISO 18000-63 protocol across the full 860 to 960 MHz UHF band, so it works with any standards-compliant reader globally, not just Siemens hardware.
Key ratings and what they mean for fit
The 128-bit EPC memory and 128-bit user memory (16 bytes accessible) give you enough space for a unique item ID plus a small payload — think serial number plus a date code or batch ID. The 320 kbit/s maximum transfer rate keeps read cycles fast in high-throughput conveyor or portal applications. Read range is listed as up to 3.5 m, but the evidence flags that overrange is possible and range depends on the specific reader and environment — so treat 3.5 m as a conservative floor, not a hard ceiling, and verify with your reader model and mounting surface. IP67 when adhered means the tag body and the adhesive bond survive washdown environments — food processing lines, outdoor logistics yards, or chemical wash cycles. The operating temperature range of -25 to +85 °C during read/write, with transient spikes to 90 °C for up to 60 minutes, covers hot-fill processes and sun-exposed outdoor racks. Storage life is capped at 2 years at 45-55% humidity, so don't stockpile these beyond that window. The tag is printable via thermal transfer process, which matters if you need variable data (serial numbers, barcodes) applied at the point of labeling rather than pre-printed. The material is PET — flexible enough to conform to curved surfaces but stiff enough to survive handling. Torsion and bending stress are conditionally permissible, meaning the tag can flex a bit but repeated creasing will crack the antenna or chip bond.
Deployment context
This tag is designed for the RF600 reader ecosystem — pair it with a SIMATIC RF680R or RF685R reader for portal or conveyor installations. The adhesive mounts onto plastic or foil surfaces; it won't stick well to bare metal without a spacer or foam-backed tag. The 45x20 mm footprint is compact enough for small asset labels (tool tracking, tote bins, medical device trays) but large enough to maintain a decent read range. The linear polarization means reader antenna orientation matters — align the tag's long axis with the reader's polarization plane for maximum range.
