Siemens 6GT2821-1AC10 SIMATIC RF200 RF210R RS422 13.56MHz IP67 RFID Reader

The Siemens 6GT2821-1AC10 is a SIMATIC RF200 RF210R RFID reader with an RS422 (3964R) interface for connecting to SIMATIC communication modules. Built into an M18 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 M18 barrel body and integrated antenna make the 6GT2821-1AC10 the smallest-footprint reader in the RF200 line, suited to tight mounting positions where a separate antenna cannot be fitted. Its RS422 (3964R) interface talks directly to a SIMATIC communication module rather than a PC, so it fits into a PLC-driven read station without protocol conversion. Against the larger M30 barrel model in this family, the smaller M18 body trades read range for mounting clearance; pick the M30 variant where the antenna needs to sit further from the tag.

Applications

Used on conveyor and assembly lines for part or carrier identification where the reader mounts through an M18 hole in a bracket or guide rail, and the -20 to +70°C, IP67 rating tolerates washdown or outdoor-adjacent installation.
