Siemens 6GT2821-2AC10 SIMATIC RF200 RF220R RS422 13.56MHz IP67 RFID Reader

The Siemens 6GT2821-2AC10 is a SIMATIC RF200 RF220R RFID reader with an RS422 (3964R) interface for connecting to SIMATIC communication modules. Built into an M30 x 71 mm barrel with an integrated antenna, it reads ISO 15693 transponders at 13.56 MHz and carries an IP67 rating for -20 to +70°C operation.

Selection Notes

The M30 barrel gives the 6GT2821-2AC10 a larger antenna coil than the smaller M18 barrel model in this family, which typically extends read range at the cost of a bigger mounting hole and a higher 40 N·m tightening torque during installation. Like the M18 barrel model, its RS422 (3964R) interface connects straight to a SIMATIC communication module, not a PC. Choose this M30 body over the smaller barrel variant when the tag-to-reader gap needs to be wider than an M18 barrel can support, and over the cuboid-body variants when a threaded barrel mount fits the application better than a flat bracket.

Applications

Used for part and carrier tracking on conveyor and assembly lines where the tag sits at a greater standoff distance than an M18 reader can reliably read, and the IP67, -20 to +70°C rating supports washdown-adjacent or outdoor-adjacent mounting.
