173-year MTBF and IP67 — what that means for uptime
The Siemens 6GT2801-3BA10 SIMATIC RF380R GEN2 RFID reader carries a calculated MTBF of 173 a — that's a mean time between failures over 173 years, which in a continuous-read station means you plan a single swap per reader lifecycle, not a quarterly replacement.
Read range and transponder dependency
Maximum read range is 200 mm, but that figure is transponder-dependent — the actual distance you get varies with the tag type and orientation. For the supported protocols (RF300 specific, ISO 15693, ISO 18000-3, ISO 14443), the range is limited by the 13.56 MHz carrier and the integrated antenna aperture. If you need the full 200 mm, match the transponder to the application note referenced in the Siemens support entry.
Interface and connection — RS422/RS232 over M12
The reader communicates via RS422 or RS232 (3964R protocol) through an M12 8-pin connector. RS422 extends up to 1000 m from the host; RS232 is limited to 30 m. That M12 pinout is the single point of connection for both power (24 VDC nominal, 20.4...28.8 V range, drawing 0.15 A typical) and data — no separate power cable. The reader is suited for RF300, ISO 15693, and MOBY E transponders, connecting to Siemens communication modules or PC systems.
