Abstract

A position sensor and sensor assembly having a spool onto which is wound a plurality of individual windings to make up a cable coil. A free end of the cable extends through a guide for attachment to an object whose position is desired to be sensed. The cable passes through an elongated slot formed the guide and which is preferably formed at a predetermined angle with respect to the central axis of rotation of the spool. By means of the elongated slot, the individual windings can be wound about the spool without successive windings overlapping each other. The elongated slot further has an internal surface that has a minimum radius to prevent the cable from making too small a bend during the winding function.
