Product Overview
The Cinch Dura-Con connector system is engineered for applications
demanding rugged, durable, and high-performance interconnects where
minimizing weight and space is crucial without compromising
reliability. Featuring the proprietary Dura-Con twist pin contact,
these connectors ensure reliable mating through a precision
miniature spring cable design that maintains contact under radial
forces. Suitable for miniaturized airborne electronics, data
processing equipment, and other demanding environments, Dura-Con
connectors offer a wide range of configurations, including
MIL-DTL-83513 compliant options, metal and plastic shells, and
various termination styles.
