Cinch Dura-Con Connectors
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
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 exhibits resistance to metal fatigue. The product line
includes MIL-DTL-83513 series connectors and their commercial
equivalents, offering a broad range of termination and hardware
options for various applications.
