I'm looking for a device that is similar to a reed switch, but with no moving parts.
I'm sure I've read something about a similar device that uses a permanent magnet and a coil type device, and the voltage induced into the coil indicates a passing motion of the magnet near by..
It’s for use with a speedometer, and would like to use something that will have a longer life span than a standard reed switch.
Any ideas?
