The Siemens 6GT2801-1AB10 is a SIMATIC RF310R reader in the RF300 family, built for reading and writing to RF300 and ISO 15693 transponders (MDS Dxxx types) over an RS422 interface using the 3964R protocol. It operates at 13.56 MHz with a maximum transfer rate of 106 kbit/s, and its read/write access time per byte is typically 0.13 ms. The reader draws 0.05 A at 24 V DC typical, with a supply range of 20.4 to 28.8 V DC. It connects via an M12 8-pin connector and is fastened with four M5 screws.
Where it goes and what it survives
The RF310R carries an IP67 rating, meaning the housing and the M12 connector are sealed against dust and temporary immersion — it can handle washdown on a production line or exposure to weather on a conveyor. Shock resistance per EN 60721-3-7 Class 7 M2 (500 m/s²) and vibration at 200 m/s² confirm it can live on a machine that sees impacts and shaking. The housing is anthracite PA 12 (nylon), and the part is silicone-free — important for paint-shop or potting applications where silicone contamination is a concern.
Maximum range is 60 mm, dependent on transponder type. The RS422 interface uses the 3964R protocol. MTBF is 154 years.
