Dura-Con Connectors by Cinch
Product Overview
Cinch Dura-Con connectors are engineered for applications demanding rugged, durable, and high-performance interconnects. Ideal for situations where minimizing weight and space is critical while maintaining maximum reliability, Dura-Con connectors are a top choice 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, designed for exceptional reliability under radial forces and repeated flexing. Cinch offers a comprehensive family of Dura-Con connectors, including MIL-DTL-83513 series and commercial equivalents, with a wide array of termination and hardware options.
