Cinch Dura-Con Micro-D Connectors
Product Overview
Cinch Dura-Con connectors are engineered for demanding applications requiring rugged, durable, and high-performance interconnects. Designed to minimize weight and space while maximizing reliability, Dura-Con connectors are ideal for miniaturized airborne electronics, data processing equipment, and applications needing shorter signal paths. The core of the Dura-Con system is the unique twist pin contact, featuring a precision miniature spring cable with seven spring members that ensure consistent contact under radial forces. This design offers high reliability and resistance to shock and vibration, making them suitable for harsh environments. The Dura-Con family includes MIL-DTL-83513 series connectors and commercial equivalents, offering a wide range of termination and hardware options.
