Product details
IO-Link V1.1 RFID reader for the line
The Siemens 6GT2821-2BC32 is a SIMATIC RF220R RFID reader, part of the RF200 family, designed for reading and writing to ISO 15693 transponders (MDS Dxxx) at 13.56 MHz. It connects to an IO-Link V1.1 master over a standard M12, 4-pin connector, with a maximum cable length of 20 m between the master and the device. This is the interface choice when you need a simple, point-to-point link without a dedicated fieldbus node at the reader — the IO-Link master handles the bus mapping.
Read range and physical fit
Maximum read range is 35 mm, but this is dependent on the transponder type — check the Siemens support entry for the specific MDS tag you are using. The M30 x 1.5 threaded barrel, 83 mm long, mounts with two included nuts. The brass, nickel-plated / PBT housing is IP67-rated, meaning the reader survives washdown environments and direct spray. A 3-color LED on the housing gives local status without needing to open the panel.
Power and data timing
The radio transfer rate is 26.5 kbit/s maximum; typical read access per byte is 2.4 ms, write access 3.3 ms. The 32-byte IO process data fits within a standard IO-Link cycle. The reader is not multi-tag capable — it reads one transponder at a time, which is the expected behavior for a single-antenna M30 form factor.
Shock resistance per EN 60721-3-7 Class 7M2 at 500 m/s², vibration at 200 m/s². The MTBF is listed at 501 a. This is a current-production Siemens catalog item.
