It integrates an antenna and a 3-color LED status indicator into a compact M18 x 83 mm brass housing with IP67 sealing, so it mounts directly on a machine frame or conveyor line where washdown or dust is present. The 20 mm read range is transponder-dependent — check the Siemens support note for your specific tag type before committing the BOM line. Rated supply is 24 V DC (20.4 to 28.8 V range), drawing 0.05 A typical — light enough that a standard IO-Link master port handles it without extra power budgeting. The M12 4-pin connector mates to standard IO-Link cables; maximum cable run between reader and master is 20 m. Read and write access times are 40 ms per byte, which sets the cycle time floor for your application — if your line needs faster tag updates per station, this reader won't keep up. The MTBF of 505 years is a calculated figure under controlled conditions, not a field guarantee, but it signals a solid design for continuous-duty lines. This part carries a lifecycle status of NRND (Not Recommended for New Designs). That means Siemens no longer actively promotes it for new projects, and a future end-of-life notice is expected. Do not spec it into a new machine build without a documented last-time-buy plan. ## Integration notes Mounts via two M18 x 1 nuts (supplied) through a panel or bracket — the 83 mm body length and 18 mm diameter fit standard M18 sensor holes. The IP67 rating means the housing and connector withstand direct hose spray and temporary immersion, suitable for food, beverage, or washdown zones. The reader is not multi-tag capable and is silicon-free, which matters for potting or seal compatibility in sensitive environments.","metaTitle":"Siemens 6GT2821-1AC32 SIMATIC RF210R IO-Link RFID Reader, IP","metaDescription":"Siemens SIMATIC RF200 RF210R IO-Link RFID reader, 13.56 MHz, IP67, M18 x 83 mm, 20 mm range.
