What it is and what it does
The Siemens 6GT2800-5AC00 is a SIMATIC RF300 RF360T Epoxy card transponder — a passive RFID tag built for industrial identification loops. It operates at 13.56 MHz, the HF band that gives reliable read range through non-metallic materials without the line-of-sight requirement of barcodes. The 32 KB FRAM user memory (32765 bytes) supports read/write cycles far beyond EEPROM, so this tag handles repeated rewrite operations on a production line without wearing out. FRAM also means writes are near-instantaneous — no write-cycle delay to account for in your pick-and-place or assembly station timing. The tag is rated IP67, meaning the epoxy encapsulation seals the electronics against dust ingress and temporary immersion. On a conveyor line or in a washdown zone, that keeps the tag functional through cleaning cycles. The operating temperature range during read/write access is -25 to +75 °C, with storage tolerance from -40 to +85 °C — wide enough for parts that move through paint ovens or cold storage.
Sourcing and lifecycle
The listed MTBF of 1200 a (years) reflects the passive, solid-state nature of the FRAM tag — no battery to deplete, no moving contacts. That reliability figure supports deployment in maintenance-free identification points where replacing a failed tag would mean production downtime.
Integration and mounting
The tag is designed for the RF300 reader system — it speaks the RF300-specific protocol at up to 106 kbit/s transfer rate. It is multitag-capable, so multiple tags in the read field can be addressed sequentially without collision. The epoxy card format (85 x 54 x 2.5 mm) is sized to mount on workpiece carriers or pallets using two M3 screws through the provided fixing strap and spacer accessories. The 2.5 mm height keeps it low-profile, which matters when the tag passes through tight gaps in a handling system. The memory organization gives you a 4-byte UID (fixed, factory-programmed), 32765 bytes of user memory, and 20 bytes of OTP (one-time programmable) memory. The OTP block can be write-protected block-by-block, useful for locking serial numbers or calibration data once written. The tag is silicon-free and contains no backup battery, so it ships without hazardous-material restrictions for air freight.
Approvals and compliance
The tag carries cULus approval, covering North American installation requirements. It is not IECEx rated, so it is not certified for explosive atmospheres. The shock resistance is rated to DIN EN 60721-3-7 Class 7 M3 at 500 m/s², and vibrational acceleration to 200 m/s² — figures that confirm it survives the mechanical stress of automated handling and transport.
