Product Overview
The Cinch Dura-Con connector system is engineered for applications
demanding rugged, durable, and high-performance interconnectivity,
particularly where minimal weight and space are critical while
maintaining maximum reliability. These connectors are ideal for
miniaturized airborne electronics and data processing equipment
requiring shorter signal paths. The core of the Dura-Con system is
the unique twist pin contact, featuring a precision miniature
spring cable with seven spring members that ensure consistent
contact under radial forces and are resistant to metal fatigue. The
product line includes MIL-DTL-83513 compliant connectors and
commercial equivalents, offering a broad range of termination and
hardware options for various applications, including custom
assemblies.
