Abstract
A sensor that includes an actuator having a plurality of actuator magnets. A detector proximate to and mechanically isolated from the actuator defines a bore. A detector magnet inside the bore may move in the bore from a first position to a second position. An optical signal passes through the detector so that the detector magnet blocks the optical signal when the detector magnet is in the first position.
