ンサ。[Claims for Utility Model Registration] Two permanent motors that are connected to a rotating shaft for detecting rotational speed, rotate, have north and south poles alternately in the direction of rotation, and are installed so that different poles face each other. A rotation sensor comprising a magnet, and a Hall IC that is fixedly attached between the two permanent magnets and outputs a change in the direction of the magnetic force of the permanent magnet as a pulse signal when the permanent magnet rotates, A Zener diode with a breakdown voltage slightly higher than the rated voltage of the Hall IC is connected between the power input terminal and the ground terminal of the Hall IC, and this diode is installed inside the rotation sensor. Rotation sensor with protection circuit.
