Rotation detector

Abstract

Abstract PURPOSE:To raise a heat resisting property, and to execute a detection at an extremely low speed, too, by improving a heat resisting property of an element itself by using a ferromagnetic material element, and on the other hand, compensating a drop of a sensitivity by a bridge of a differential constitution. CONSTITUTION:Four ferromagnetic material magneto-resistance element 1, 2 are provided in the vicinity of a magnetic pole of a magnet 3, and these elements are connected by a bridge of a differential constitution. A rotation sensor of such a constitution is installed so as to hold a prescribed gap to a gear 9 by a screw provided on the outside circumference of a housing 6.
