Hall-Effect Zero Speed  Sensor Diagram

Non-contact magnetic sensors that measure the distortion of magnetic field created by a ferrous target. Hall-Effect Zero speed sensors provide very precise measurements of movement even at zero speed which makes the Hall-Effect zero speed sensors ideal for speed measurements. Hall-effect zero speed sensors provide digital output with constant amplitude signal regardless of variation of the speed.
