Cinch Dura-Con Connectors
Product Overview
Cinch Dura-Con connectors are engineered for applications demanding rugged, durable, and high-performance interconnectivity. Designed to minimize weight and space while maximizing reliability, Dura-Con is ideal for miniaturized airborne electronics, data processing equipment, and scenarios requiring shorter signal paths. The core of the Dura-Con system is the precision twist pin contact, featuring a miniature spring cable with a welded tip. This design ensures consistent contact through seven spring members around the pin, providing resistance to radial forces and exceptional durability against metal fatigue. Cinch offers a comprehensive family of Dura-Con connectors, including MIL-DTL-83513 series and commercial equivalents, with extensive termination and hardware options.
