Abstract
A coaxial capacitor contacting and sealing structure, for electrical continuity between parts that move in relation to each other at the ends of a cavity within a hydraulic cylinder employing electromagnetic wave position sensing. The structure employs a contacting and sealing member having a high surface conductivity that is mounted in one of the parts. The mounting of the contacting and sealing member provides force for pressure contact in oil between the parts and to enhance electrical continuity with the part in which the contacting and sealing member is located.
