WebApr 14, 2024 · Reed switches have a bounce/settling time that needs to be considered. Reed switches use no power in an open state. Reed switches are binary devices; they cannot tell between magnetic north and south poles. Hall effect sensors are digital devices; they do not experience a physical contact bounce. Hall effect sensors constantly drain a small ... WebIn addition, these relays work with advanced methods. For instance, an RF reed relay is mainly designed for switching high-frequency signals. Arranging a coaxial shield in the region of the reed switch simply allows the relay to switch signals equal to 7 GHz. The reed relay operating speed ranges from 200 µs – 500 µs.
