The Siemens 6GT2801-0AA00 is a SIMATIC RF300 RF310R RFID reader designed for the IQ-Sense interface, operating at 13.56 MHz with a maximum transfer rate of 106 kbit/s. It reads and writes RF300 transponders at a typical access time of 20 ms per byte for reads and 25 ms per byte for writes, with a maximum range of 35 mm that depends on the specific transponder type used. The IP67 protection class means the reader body withstands washdown environments and temporary submersion — suitable for deployment on conveyor lines, pallet-handling stations, or in food-and-bev zones where the housing sees direct spray.
The listed MTBF of 23 years provides a reliability benchmark for maintenance planning — it reflects the mean time between failures under continuous operation in the rated environmental conditions.
Integration notes
Mounting is via 4 x M5 screws into the panel or bracket; the housing dimensions are 55 mm wide, 75 mm deep, and 30 mm tall, so it fits a standard enclosure footprint without crowding adjacent components. The electrical connection is an M12, 4-pin male connector — the standard industrial sensor/actuator interface. Power is 24 V DC nominal (20.4 to 28.8 V range), drawing 0.04 A typical at 24 V. The housing material is PA 12 (polyamide) in anthracite color, rated for shock resistance to EN 60721-3-7 Class 7 M2 at 500 m/s² and vibration at 200 m/s².
Communication and protocol
The reader communicates exclusively via the IQ-Sense protocol — it is not a Modbus or PROFINET device natively. That limits it to Siemens IQ-Sense-capable controllers or gateways. The RF300-specific radio protocol handles the air interface to the transponders; the reader is not multitag-capable, so it reads one tag at a time.
