It operates at 13.56 MHz (HF) and reads ISO 15693 and ISO 18000-3 transponders — the MDS Dxxx family — making it a drop-in for Siemens RFID infrastructure on conveyor lines, pallet identification, and work-in-progress tracking stations. The IP67 rating means the reader body and the integrated antenna survive washdown environments — food processing, automotive paint shops, or outdoor gate readers. The 200 mm read range depends on the transponder type; for the actual range with your tag, Siemens provides an application note (support.automation.siemens.com). The housing is PA 12 (silicon-free) in Ti gray, 160 mm deep × 80 mm wide × 41 mm tall. Fastening is via 4 × M5 screws — no DIN-rail clip, so plan for direct panel or bracket mounting. Shock resistance is EN 60721-3-7 Class 7 M2 at 500 m/s²; vibration at 200 m/s² — rated for machine-mounted applications near presses or conveyors. No last-time-buy window is active. If you are stocking spares for an existing RF280R installation, this is the exact match — no rewiring or reconfiguration needed.","metaTitle":"Siemens 6GT2821-8AC10 SIMATIC RF280R RFID Reader, RS422, IP6","metaDescription":"Siemens SIMATIC RF200 RF280R RFID reader with RS422 interface (3964R), IP67, 13.56 MHz, 200 mm range, 3-color LED, MTBF 173 y.

This is a calculated reliability metric for the electronics — useful for comparing expected service life in continuous-duty applications, especially in hard-to-access locations."},{"question":"What transponder types does this reader work with?","answer":"It reads ISO 15693 and ISO 18000-3 transponders, specifically the Siemens MDS Dxxx family. The 200 mm range is dependent on the transponder type; Siemens provides a range calculator for exact values."},{"question":"What connector and cable length are supported?","answer":"The reader uses an M12 8-pin connector for both power and RS422 communication. The RS422 interface supports cable runs up to 1000 m, allowing remote placement from the controller."},{"question":"Does the 6GT2821-8AC10 drop into a panel wired for a Siemens PLC like 6ES7314-1AE04-0AB0?","answer":"No — this is an RFID reader, not a PLC.
