CINCH M83513/01-CN

Dura-Con Connectors

Product Overview
Cinch Dura-Con connectors are engineered for applications demanding rugged, durable, and high-performance interconnects, particularly where minimizing weight and space is critical while maintaining maximum 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 unique twist pin contact, featuring a precision miniature spring cable with seven spring members that ensure consistent contact with the mating socket wall under radial forces. This design offers exceptional resistance to metal fatigue and provides reliable mating, further enhanced by a tightly toleranced recessed cavity protecting the pin contact.
