The Cinch Dura-Con connectors, manufactured by Bel, are designed for applications demanding rugged, durable, and high-performance interconnects where minimizing weight and space is critical without compromising 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 precision miniature spring twist pin contact, ensuring reliable contact under radial forces and offering excellent resistance to metal fatigue. The product line includes MIL-DTL-83513 connectors and commercial equivalents, with a wide range of termination options, hardware, and custom capabilities.
