Applications

The TLE4959C FX is an integrated differential Hall speed sensor ideally suited for transmission applications. Its

basic function is to provide information about rotational speed and direction of rotation to the transmission

control unit. TLE4959C FX includes a sophisticated algorithm which actively suppresses vibration while

keeping excellent airgap performance.
