Learn about Cinch’s rugged and high performing Dura-Con line of products that are compact and ideal for weight and space sensitive applications.
Cinch Dura-Con connectors are rugged, high-performance compact interconnects that are ideal for weight and space sensitive applications that demand maximum reliability, they're among the most widely used 0.05 inch pitch connectors and are ideal for navigation and guidance systems, smart munitions, aerospace, downhole equipment for oil and gas, and other harsh environment applications. Dura-Con connectors are based on a unique twist pin contact design that expands outwards. This creates seven contact points when mated, ensuring low contact resistance and a reliable connection even when subjected to high levels of shock and vibration.

Cinch Dura-Con D-shaped Micro Miniature Connectors are available in over 5,000 configurations that are qualified to MIL-DTL-83513 standards. Plugs and sockets are offered with nine to 100 positions and with metal shells that provide EMI shielding and enhanced robustness or plastic shells that are lighter and more economical. Both are available in wire, solder cup, or PCB terminations. PCB mount versions offer three solder pin lengths and straight and right angle configurations, as well as a narrow right angle option for reduced panel spacing. Dura-Con MIL-DTL-83513 connectors are rated for 600 volts ACS sea level. Commercial and high temperature variants are also available.

Dura-Con Micro-D hermetic connectors add a proprietary epoxy compound resin that has a lower applied cost than glass sealed connectors, and maintains its seal under high vibration in shock where glass seals fail. The connectors have a Fluoro-silicone O-ring to seal against the panel and have a total leak rate of less than 1 x 10 to the negative 8 cc's per second of helium cross a 1 atmosphere pressure differential. Dura-Con hermetic connectors used the same rugged twist pin contact and are rated for 900 volts AC at sea level. Cinch also offers Dura-Con strip connectors for applications with the most extreme space and weight constraints at the lowest cost and Dura-Con microedge connectors to support legacy edge mount applications.
