The Siemens 6GT2801-2AB10 is a SIMATIC RF300 RFID reader (type RF340R) operating at 13.56 MHz with an integrated antenna and RS422 interface using the 3964R protocol. It reads and writes RF300-specific and ISO 15693 transponders, with a typical read access time of 0.13 ms per byte and write access time of 0.13 ms per byte. The maximum transfer rate over the radio link is 106 kbit/s. The reader draws 0.1 A typical at 24 V DC from a supply range of 20.4 to 28.8 V DC. It connects via an M12 8-pin connector and is designed for operation with Siemens communication modules. The RS422 interface supports cable runs up to 1000 m.
The 140 mm maximum read range depends on the transponder type. Verify range with your specific tag against the Siemens application note. IP67 protection means the reader withstands dust ingress and temporary immersion in water — suitable for washdown areas in food processing or automotive machining lines. The PA12 housing and silicon-free construction avoid contamination issues in painting or coating environments. The MTBF of 140 years signals a robust design for continuous-read applications where downtime for replacement is costly. This figure supports the reliability case for Tier-1 automotive lines requiring full part genealogy tracking. The shock resistance rating of 500 m/s² per EN 60721-3-7 Class 7M2 confirms it survives vibration on conveyor systems and robotic cells.
The reader measures 75 x 75 x 41 mm and mounts via two M5 screws. The anthracite housing blends into standard machine frames. The M12 8-pin connector handles both power and RS422 communication — one cable, one connection point. Because the reader is not multitag-capable, position tags sequentially through the read zone. The 13.56 MHz frequency provides good read performance on metal surfaces when paired with appropriate RF300 or ISO 15693 tags.
