Cinch Dura-Con connectors are engineered for applications demanding rugged, durable, and high-performance interconnect solutions. These connectors are ideal 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 unique Dura-Con twist pin contact, designed for reliable mating under radial forces and offering excellent resistance to metal fatigue. The product line encompasses 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.
