A position sensor 10 for a rotating shaft 12 includes a coil 44 of small diameter litz wire wound around a ferrite rod 42. The rod is secured in the end of a ceramic support 40 and an end cap 43 is secured on the other end of the rod to form a bobbin section on which the coil is wound. Two palladium silver strips 53 are formed axially along the length of the support extending from the bobbin section to near the base of the support. Two free ends 51 of the coil are formed into strain relief loops and soldered to the strips. Lead wires (46, fig.6) of comparatively larger diameter are also soldered to the strips but near the base of the support. The strips establish electrical continuity between the coil and the lead wires while separating the end portions of the coil from the lead wires so as to prevent the lead wires from inducing stress into the relatively fragile coil wires. <IMAGE>
