Dura-Con Micro-D Connectors
Product Overview
Cinch Dura-Con connectors are engineered for applications demanding rugged, durable, and high-performance interconnects where minimizing weight and space is critical without compromising reliability. The core of the Dura-Con system is the precision twist pin contact, featuring a miniature spring cable with seven spring members that ensure consistent contact under radial forces. These connectors are ideal for miniaturized airborne electronics, data processing equipment, and other applications requiring shorter signal paths. The Dura-Con family includes MIL-DTL-83513 series connectors and their commercial equivalents, offering a wide range of termination and hardware options, including wire versions, PC board mount connectors, and high-density microminiature edge connectors. Custom capabilities are also available to meet specific application requirements.
