Abstract

Some aspects described herein involve a multi-turn counter (MTC) system that includes a first MTC sensor configured to sense a rotating magnetic field coupled to a rotatable object. The first MTC sensor may have a first sense of rotation detection. The MTC system may include a second MTC sensor may be configured to sense the rotating magnetic field. The second MTC sensor may have a second sense of rotation detection which is opposite to the first sense of rotation detection, and the second MTC sensor is configured to sense the rotating magnetic field according to the second sense of rotation.
