What it is and where it fits
The Siemens 6GT2810-3AC10 is a SIMATIC RF642L SmartLabel PET — a printable, on-metal UHF RFID label built for the RF600 system. It operates in the 902 to 928 MHz band (FCC) and follows the EPCglobal Class 1 Gen 2 / ISO 18000-63 protocol, so it works with standard UHF readers that support that air interface. The label measures 50 x 22.5 x 1.65 mm, with a white PET top side that accepts thermal-transfer printing. It is one-side adhesive for direct application to metal surfaces.
Lifecycle and sourcing reality
Minimum order quantity is 500 units (one roll). This is a standard label roll — you buy the full reel, not singles. For a BOM line or a critical spare, confirm the quantity per reel matches your tag count requirement. Sourced to order against an RFQ. Because it's an active, mature part, lead time is typically Siemens standard for RFID consumables — no broker or surplus channel needed.
