What It Is — And What It Handles
The Siemens 6GT2810-3AC00 is a SIMATIC RF642L SmartLabel PET — a UHF RFID transponder label designed for on-metal mounting. It operates in the 865 to 868 MHz ETSI band and follows the EPCglobal Class 1 Gen 2 / ISO 18000-63 protocol, so it drops into any standard UHF RFID infrastructure without a proprietary reader lock-in. Rated IP68, the label survives washdown environments and outdoor exposure — suitable for asset tracking on metal equipment in food processing, automotive assembly, or tire-curing lines where steam and high-pressure cleaning are routine. The read range reaches up to 2.8 m, though this is reader-dependent; the system manual (RF600) notes overrange is possible depending on the reader model. For a curing press application, expect reliable reads through the press cycle if the antenna is positioned within a couple of meters.
Physical Fit And Installation
Dimensions are 50 mm wide, 22.5 mm deep, and 1.65 mm tall — a slim profile that fits on curved or flat metal surfaces. The top-side material is PET, printable via thermal transfer process, so you can add barcodes or human-readable text during label production. Fastening is one-side adhesible — peel and stick. The label is silicon-free, which matters for applications where silicone contamination affects downstream processes like painting or bonding. Torsion and bending stress are conditionally permissible, so avoid mounting on highly flexible surfaces or repeated flex zones.
Memory And Chip Details
Built around the NXP UCODE 7xm-2K transponder chip, the label offers EPC memory of 96 bit (12 byte) assigned with a sequential identifier, expandable up to 448 bit (56 byte). User memory is 2048 bit (256 byte), and TID memory is 96 bit (12 byte). Memory features include lock, unlock, kill, write protection, and password protection — useful for securing asset data against tampering. Maximum transfer rate is 320 kbit/s, adequate for high-speed conveyor applications where multiple tags pass the read zone quickly. The label is multitag-capable, so it works in dense-read environments.
Environmental Ratings
Operating temperature during read/write access is -20 to +85 °C; outside the read/write area, the range extends to -25 to +85 °C. Storage temperature is 13 to 23 °C. These ranges cover most industrial indoor environments but note the storage restriction — don't leave rolls in an unheated warehouse in winter.
