Operating temperature spans -20 to +70 °C, so it handles ambient conditions inside a non-conditioned enclosure or near process heat. The 13.56 MHz HF band gives a read range up to 60 mm, though actual reach depends on the transponder type — the RFID system integrator should verify compatibility with the specific tag in use.","metaTitle":"Siemens 6GT2821-5AC10 RF250R RFID Reader, RS422, 13.56 MHz","metaDescription":"Siemens SIMATIC RF250R RFID reader (6GT2821-5AC10) with RS422 interface, 13.56 MHz, IP65, active production.
