Dura-Con Connectors by Cinch
Product Overview
Cinch Dura-Con connectors are engineered for applications demanding
rugged, durable, and high-performance interconnects. Designed to
minimize weight and space while maximizing reliability, Dura-Con
connectors are ideal for miniaturized airborne electronics and data
processing equipment requiring shorter signal paths. The core of
the Dura-Con system is the precision twist pin contact, featuring a
spring cable design that ensures consistent contact under radial
forces and repeated flexing without metal fatigue. Cinch offers a
comprehensive family of Dura-Con connectors, including
MIL-DTL-83513 series and commercial equivalents, with a wide array
of termination options and hardware configurations.
