Introduction | Part Numbers

Dura-con Introduction

The Cinch Microminiature Dura-Con line of connectors qualified (QPL) to MIL-DTL-83513 is one of the most widely used .050 inch (1.27mm) pitch connectors for military and high-end commercial applications. Dura-Con is ideal where packaging requires a small size and low weight, as well as a highly reliable and rugged connector that has electrical and mechanical integrity under extreme vibration and shock conditions. The heart of the Dura-Con System is the unique wire form pin that provides seven points of contact when mated to the socket. Applications include electronics in missiles, aircraft, launch vehicles, satellites and computers.

Dura-Con connectors are available as all plastic in 9, 15, 21, 25, 31, 37 and 51 positions and metal shell versions in 9, 15, 21, 25, 31, 37, 51 and 100 positions. In addition, Cinch also offers Metal Shell Micro Edge Dura-Con Connectors in 128 and 184 positions, strip connectors up to 60 positions and connector savers. Termination can be solder cup, wired leads or PC mount.

As well as Standard Parts, Cinch provides a wide variety of specials and wired harnesses to industry. Please contact us with your custom or harness needs.

Dura-Con™ Twist Pin Technology
