Cinch Dura-Con connectors are engineered for applications demanding rugged, durable, and high-performance interconnects, especially where minimizing weight and space is critical without compromising reliability. These connectors are ideal for miniaturized airborne electronics and data processing equipment requiring shorter signal paths. The core of the Dura-Con system is the unique twist pin contact, featuring a precision miniature spring cable with seven spring members that ensure consistent contact under radial forces and resist metal fatigue. Cinch offers a comprehensive family of Dura-Con connectors, including MIL-DTL-83513 series and commercial equivalents, with expanded termination and hardware options, as well as high-density microminiature edge connectors and connector savers for high-mating cycle applications.
