ABSTRACT:
A low torque magnetic pick-off assembly has both a stationary magnet and a magnet mounted on a rotating member. The stationary magnet is oriented parallel to the axis of the rotating member and is used to establish a magnetic field in a field guide passing through a coil. The magnet on the rotating member modulates the magnetic field passing through the coil thereby inducing an output voltage in the coil. The output voltages indicates the passage of the magnet on the rotating member past the stationary magnet.
