A method for forming a non-contact position sensor having a predetermined stroke length comprises providing a pair of coil assemblies each comprising a primary and secondary coil of a predetermined size; providing a core member of varying magnetic density about its length; and inserting the core member within the coil assemblies, whereby axial movement of the core member relative to the coil assemblies causes a corresponding output signal from the coil assemblies indicative of the position of the core member.
