Cinch Dura-Con 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. 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 under radial forces,
offering excellent resistance to metal fatigue. The Dura-Con family
includes MIL-DTL-83513 series connectors and their commercial
equivalents, offering a wide range of termination and hardware
options for various application needs.
