Cinch Dura-Con Connectors

Cinch Dura-Con connectors are engineered for applications demanding rugged, durable, and high-performance interconnects. These connectors are ideal for scenarios where minimizing weight and space is critical, while maintaining maximum reliability. Typical applications include miniaturized airborne electronics and data processing equipment requiring 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. The Dura-Con family includes MIL-DTL-83513 series connectors and their commercial equivalents, offering a wide range of termination and hardware options for various wire and PCB mounting configurations.
