Abstract
Apparatus for establishing a 'home' position for a load element driven axially along the lead screw. A position sensor includes a first sensor element attached for axial travel with the load element and a second sensor element attached for rotation with the lead screw. The pair of sensor elements is operatively aligned at a predetermined relative axial and rotational position establishing the 'home' position.
