The Siemens 6GT2810-2EE01 is a SIMATIC RF625T Disk Tag — a 30 mm diameter by 8 mm height on-metal RFID transponder built for the RF600 system. It operates in the 902 to 928 MHz FCC band using the EPCglobal Class 1 Gen 2 / ISO 18000-63 protocol, with a read range up to 1.5 m depending on the reader and environment. The tag is designed to be mounted directly on metal surfaces, which is where most commodity RFID tags fail — the PA6.6 housing and ferrite-backed construction keep detuning under control when the tag sits against a steel panel or machine frame. The IMPINJ MONZA 4QT chip inside gives you 128-bit EPC memory (expandable from 96-bit sequential ID) and 64 bytes of user-accessible memory. That user memory is what makes this tag useful for more than just an ID — you can write a maintenance history, a calibration timestamp, or a lot code directly onto the tag so it travels with the asset. The memory supports lock, unlock, write protection, and password protection, so you can lock the EPC and still update the user block in the field.
Environmental sealing and mechanical survival
IP68/IPx9K means this tag survives continuous immersion beyond 1 m and high-pressure, high-temperature washdown — the kind you get on food-processing lines or in foundry cleaning bays. The shock resistance is rated to 1000 m/s² per DIN EN 60721-3-7 Class 7M3, and vibrational acceleration to 500 m/s². That is not a lab number; it means the tag stays attached and readable on a die-cast machine or a conveyor transfer point where standard tags rattle off or lose their antenna bond. Temperature range outside the read/write area is -40 to +125 °C; during read/write access it narrows to -25 to +85 °C. The storage range matches the wider band, so the tag can sit on a hot engine block or in a cold warehouse without degrading. Fastening is by M3 screw or gluing — no DIN rail, no bracket, which is typical for a disk tag that gets epoxied or bolted directly to the asset.
