Cinch Dura-Con connectors are engineered for applications demanding robust, durable, and high-performance interconnect solutions. These connectors are ideal for scenarios where minimizing weight and space is critical without compromising reliability. Typical applications include miniaturized airborne electronics and data processing equipment that require shorter signal paths. The core of the Dura-Con system is the Dura-Con twist pin contact, featuring a precision miniature spring cable with a welded tip. This design ensures reliable contact under radial forces and offers excellent resistance to metal fatigue. Cinch's Dura-Con family includes connectors compliant with MIL-DTL-83513 and commercial equivalents, offering a wide array of termination and hardware options for wire and PCB mount versions.
