The Siemens 6GT2801-1AB20-0AX1 is a SIMATIC RF300 Reader RF310R running in ISO scan mode, built for serial connection to control systems. It reads RF300-specific and ISO 15693 transponders (MDS Dxxx family) at 13.56 MHz, with a maximum read range of 60 mm — though that range depends on the specific transponder type you pair it with. Communication runs over an RS422 interface at distances up to 1000 m, using protocols that include RF300-specific, ISO 15693, and ISO 18000-3. Typical read access per byte clocks in at 0.13 ms, with a maximum transfer rate of 106 kbit/s over the radio link.
Mounting and environment — what IP67 means here
The housing is PA 12 in anthracite, sealed to IP67. That means the reader body and its M12 8-pin connector withstand washdown, dust, and temporary immersion — suitable for food-and-bev lines, machining coolant splash, or outdoor stations where you'd rather not build a separate enclosure. Mounting is via 4 x M5 screws through the rotated base plate. The footprint is 75 mm wide, 55 mm deep, 30 mm tall — compact enough to tuck into tight machine frames. It's rated for shock resistance per EN 60721-3-7 Class 7 M2, handling 500 m/s² shock and 200 m/s² vibration. That's the kind of spec that matters when the reader is bolted directly to a press or a conveyor frame rather than isolated on a panel door.
Power and wiring
Powered at 24 V DC nominal (20.4 to 28.8 V range), drawing 0.05 A typical at 24 V. The M12 8-pin connector handles both power and RS422 signals in one cable run — keeps the wiring clean and reduces a point of failure compared to separate power and comms cables. The reader is not multitag-capable, so it reads one transponder at a time.
The listed MTBF is 170 years.
