Cinch Dura-Con connectors are engineered for applications demanding rugged, durable, and high-performance interconnects. Designed to minimize weight and space while maximizing 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 precision twist pin contact, featuring a spring cable with seven spring members that ensure consistent contact under radial forces and repeated flexing without metal fatigue. The family includes MIL-DTL-83513 series connectors and commercial equivalents, offering a wide range of termination and hardware options for various applications.
