Dura-Con Connectors
Product Overview
Cinch Dura-Con connectors are engineered for applications demanding rugged, durable, and high-performance interconnects. Designed to minimize weight and space while maximizing reliability, Dura-Con is 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 maintain contact under radial forces, ensuring reliable mating even after numerous flex cycles. The Dura-Con family includes MIL-DTL-83513 connectors and their commercial equivalents, offering a wide range of termination options and hardware for various applications.
