The Siemens 6GT2821-4BC32 is an SIMATIC RF240R RFID reader from the RF200 family, designed to read and write to ISO 15693 and ISO 18000-3 transponders at 13.56 MHz. It communicates via an IO-Link V1.1 interface to a master, with a maximum cable length of 20 m between reader and master. The integrated antenna gives a read/write range up to 65 mm, though actual range depends on the transponder type — Siemens application note 67384964 covers the pairing.
The listed MTBF is 430 a (years). This is a reliability figure for the reader under rated operating conditions.
The housing colour is anthracite.
No. The 6GT2821-4BC32 is an RFID reader with an M12 connector and IO-Link interface, while the 6ES7222-1BF22-0XA0 is a digital output module for a SIMATIC S7-200 PLC with screw terminals. They serve completely different functions and are not mechanically or electrically interchangeable.
The evidence does not list RoHS, REACH, UL, or IEC certifications for this specific order code. The reader is designed for operation with ISO 15693 transponders and IO-Link V1.1 masters, and its shock/vibration ratings reference EN 60721-3-7. For full compliance declarations, consult Siemens documentation or request them with an RFQ.
