Abstract
The present invention relates to a position sensor and limit switch apparatus for an actuator. The actuator has a cylinder and a piston with at least one magnetized portion reciprocatingly disposed within the cylinder. The apparatus includes an elongate housing aligned parallel with the cylinder. A magnetostrictive linear displacement transducer is disposed within the housing for sensing the position of the at least one magnetized portion. The apparatus includes a switch means responsive to the transducer for operatively interrupting actuation of the piston upon the at least one magnetized portion reaching a limit position.
