Dura-Con Micro-D 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 while maintaining maximum
reliability. Featuring the Dura-Con twist pin contact, these
connectors offer exceptional reliability through a precision
miniature spring cable design that ensures consistent contact under
radial forces. Ideal for miniaturized airborne electronics, data
processing equipment, and applications requiring shorter signal
paths, Dura-Con connectors provide robust solutions for harsh
environments.
