The Cinch Dura-Con connector system, a product of Bel, is engineered for applications demanding rugged, durable, and high-performance interconnects 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 precision twist pin contact, featuring a miniature spring cable with seven spring members that ensure consistent contact under radial forces, offering excellent resistance to metal fatigue. The Dura-Con family includes MIL-DTL-83513 connectors and commercial equivalents, with expanded termination and hardware options, as well as high-density microminiature edge connectors meeting MIL-C-55302 requirements. Connector savers are also available for applications with very high mating cycles, such as test equipment.
