Cinch Dura-Con Micro-D Connectors
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 design that ensures consistent contact under radial forces and offers excellent resistance to metal fatigue. These connectors are available in various configurations, including MIL-DTL-83513 compliant series and commercial equivalents, with extensive options for termination, hardware, and mounting.
