Cinch Dura-Con Connectors
Product Overview
Cinch Dura-Con connectors are engineered for applications demanding
rugged, durable, and high-performance interconnectivity. Designed
to minimize weight and space while maximizing reliability, Dura-Con
is ideal for miniaturized airborne electronics, data processing
equipment, and scenarios requiring shorter signal paths. The core
of the Dura-Con system is the precision twist pin contact,
featuring a miniature spring cable with a welded tip. This design
ensures consistent contact through seven spring members around the
pin, providing resistance to radial forces and exceptional
durability against metal fatigue. Cinch offers a comprehensive
family of Dura-Con connectors, including MIL-DTL-83513 series and
commercial equivalents, with extensive termination and hardware
options.
