Hall Effect Digital Speed Limit Switch Diagram

Non-contact magnetic sensors that measure the distortion of magnetic fields and thus provide a precise measurement of a specified speed range by switching the output from logic high to logic low at a minimum speed and from logic low to logic high at the maximum speed that is required for your application.
