摘要： A magnetic linear position sensor includes an array of N number of magnets. The array of magnets is distributed along a line to form a magnetic field relay along the line. The sizes and positions of the magnets in the array of magnets are symmetric along the line, and the size of the magnets decreases from the sides of the array of magnets towards the center of the array of magnets. The magnetic linear position sensor further includes a magnetic field sensor spaced apart and positioned above the array of magnets. The magnetic field sensor moves back and forth over the array of magnets to sense the magnetic field of the array of magnets.

摘要： A linear sensor system includes a first field sensor displaced linearly from a second field sensor. A member having high magnetic permeability is disposed between the first field sensor and the second field sensor. The member is optimized in shape and material to completely remove any redirection or interference of the magnetic flux in the field sensors. A torque transmitting device incorporating the linear sensor system is also disclosed.
