Latest-generation solutions for harsh-environment
applications ranging from C4ISR to space flight
Micro-military circular
connectors and cable assemblies
Micro-military circular connectors
Eaton’s micro-military circular connectors incorporate latest-
generation designs that deliver uncompromised performance
in harsh environment applications ranging from C4ISR to
space flight. Additional features include:
• Significantly smaller sizes, lower weights, and higher
contact densities than MIL
--DTL
--38999
connectors.
• Coupling mechanisms that stay engaged in high shock and
vibration environments and redundant insert retention.
• A comprehensive range of solutions; dual start: shell sizes
6 – 10 and triple start: shell sizes 8 – 12.
• Mating compatibility with micro-miniature connectors from
other manufacturers.
