    Patent number: 6064200
    Abstract: The present invention relates to a direct connector type magnetic revolution sensor for detecting the number of revolutions of a rotating axis in for example an automotive transmission, and intended to present reliable, yet inexpensive, magnetic revolution sensors, with which the varying connector specifications are easily met by using a detection block as the common component.The magnetic revolution sensor comprises a detection block(2); a cap(1) for protecting the block; and a connector block(3) having a flange(3a) on which a space for installing said detection block(2) and said cap(1) is provided, as well as connector terminals(10) in the other end thereon separated by said flange(3a). The detection block(2) attached on said installing space being electrically coupled with said connector terminals (10). The detection block, a key component for the reliability, is used as the common constituent component having an established reliability.
