Connection Technology
Our DCHM Dura-ConTM productis capable of meeting the extreme mechanical and electrical needs in the harshest
enviroments of military/aerospace and industrial applications, such as downhole drilling. Cinch has teamed our proven
twist pin technology with unique plug insulators that preovide increased electrical protection between cavities.
These plugs mate to our right angle PCB socket connectors, to make a connector system that offers superior performance.
This technology also provides the condence and reliability needed in high temperature, vibration and shock applications.
