The Siemens 6GT2821-5AC40 is a SIMATIC RF200 RF250R ASCII RFID reader with an RS232 interface running in ASCII/scan mode and no built-in antenna, requiring a separate ANT-series antenna. Housed in a 50 x 50 x 30 mm IP65 enclosure, it reads ISO 15693 transponders at 13.56 MHz and connects directly to a PC or control system.

Selection Notes
This variant combines the RF250R's split antenna design (M8, 4-pin antenna port, ANT-series antenna purchased separately) with an RS232 ASCII/scan-mode interface, so it connects directly to a PC or scanner input instead of a SIMATIC communication module. The 30 m maximum wire length is much shorter than the RS422 version's 1000 m, which puts this reader close to the connected PC. Choose it over the RS422 version when the endpoint is a PC or third-party scanner rather than a SIMATIC module, and keep the RS422 version for longer cable runs back to a communication module.
Applications
Used where the antenna must be positioned apart from the reader body and the read data needs to reach a nearby PC or terminal directly, such as manual scan stations or benchtop read/write setups.
