It operates at 13.56 MHz and communicates with ISO 15693 transponders (MDS Dxxx family) and ISO 18000-3 tags, making it a direct drop-in for Siemens RFID infrastructure in production tracking, tool identification, or work-in-progress monitoring. The IP67 rating means the reader body and the integrated antenna survive washdown environments — suitable for food-and-bev lines, paint shops, or outdoor conveyor stations where dust and water jets are routine. The housing is PA6.6 in anthracite, fastened with two M5 screws, sized at 75 x 75 x 41 mm. The read/write speed is 0.6 ms per byte typical, both for read and write access. That puts it in the fast-response class for a 13.56 MHz HF reader — adequate for reading a 16-byte UID or a small data block on a moving pallet at line speed, but not for bulk data transfer per tag. Maximum range is 135 mm, but this is dependent on the transponder type. For a 50 mm diameter disc tag you might get the full 135 mm; for a smaller nail-type tag the usable range drops. The Siemens support note (ID 67384964) gives the per-transponder range table — worth checking before you commit the mounting bracket position. The M12 8-pin connector carries both power and RS-232. Maximum cable length to the host PC is 30 m at RS-232 levels — beyond that you'll need a converter or a remote I/O drop. The reader is not multitag-capable; it reads one transponder at a time. ## Environmental tolerance Shock resistance is tested to EN 60721-3-7 Class 7M2 at 500 m/s², and vibration resistance at 200 m/s². That covers most industrial conveyor and machine-tool environments, including near presses or stamping lines. No last-time-buy clock is ticking, but for a long-life production line it is worth verifying the lifecycle status annually — Siemens typically gives 12–18 months notice before an EOL, and the RF200 family has been superseded in some roles by the RF300 series.","metaTitle":"Siemens 6GT2821-6AC11 SIMATIC RF260R RFID Reader, 13.56 MHz,","metaDescription":"Siemens 6GT2821-6AC11 SIMATIC RF260R RFID reader.
