It reads ISO 15693 and ISO 18000-3 transponders (MDS Dxxx series) and connects to an IO-Link master over a maximum cable length of 20 m between master and device. The reader supports one external antenna via an M8 4-pin connector; the IO-Link interface uses an M12 4-pin connector. ## Read performance and antenna pairing Typical read access per byte is 2.4 ms; write access takes 3.3 ms per byte. Maximum radio transfer rate is 26.5 kbit/s. The maximum read range is 60 mm, but this depends on the transponder type — Siemens application support document 67384964 covers the range per transponder. Compatible antennas include ANT 1, 3, 3NO, 8, 12, 18, and 30. The reader is not multitag-capable — it handles one transponder at a time. Housing is PA6.6, anthracite, 50 x 50 x 30 mm, fastened with two M5 screws. IP67-rated when the sealing washer is seated — the connector O-ring is the wet-end barrier. Shock resistance per EN 60721-3-7 Class 7M2 at 500 m/s²; vibration resistance at 200 m/s². Silicon-free construction is confirmed. MTBF is listed at 430 years. The reader carries a 3-color LED display for status indication.","metaTitle":"Siemens 6GT2821-5BC32 RF250R RFID Reader, IO-Link, IP65","metaDescription":"Siemens SIMATIC RF250R RFID reader, 13.56 MHz, IO-Link V1.1, IP65, MTBF 430 y.
