Product Overview
Cinch Dura-Con connectors, featuring the innovative Dura-Con twist pin contact, are engineered for applications demanding rugged, durable, and high-performance interconnects where weight and space are critical. These miniaturized connectors are ideal for airborne electronics and data processing equipment requiring shorter signal paths. The Dura-Con system ensures reliable mating through a precision miniature spring cable with seven spring members, providing consistent contact under radial forces and resisting metal fatigue. The product line includes MIL-DTL-83513 compliant connectors and commercial equivalents, offering a broad range of termination and hardware options for various applications.
