CDM Electronics has announced the
availability of Eaton’s latest generation of circular connectors for mission-critical
military and
aerospace applications. The micro-military circular connector series
boasts shell diameters as small as 11 mm.

The new series meets the
MIL-DTL-38999 performance and environmental requirements. It comprises
fast-mating M1 (dual-start) and M5 (triple-start) connectors optimized for
harsh environments. The circular connectors are 40% smaller, 50% lighter in weight,
and provide higher contact densities than conventional MIL-DTL-3899 connectors.


It’s worth noting that the
micro-military circular connectors require application-specific performance
modifications that include compliance to NASA low volatile condensable
materials as per ASTM E595 test method. And pin and socket crimp contacts have
to meet the MIL-C-39029

Eaton’s new ruggedized connectors also incorporate redundant retainers and an epoxy bond to
prevent insert movement within the shell. Moreover, the circular connectors are
optimized for over-molding and are supplied in shell sizes ranging from 6 to 12
with 1 to 26 contacts per connector.

These connectors have specifically been engineered
to meet or exceed the stringent mechanical and electrical requirements
essential for military and aerospace applications. That includes commercial and
private aircraft avionics, engine management systems, weapons systems, and in-flight

These circular connectors are
offered as plugs and receptacles in inline, jam nut, and square flange formats.
Their aluminum shells may be ordered with RoHS-compliant electroless nickel or
in cadmium and olive drab finishes.

CDM Electronics, a distributor of
electronic connectors and cables, is also offering Eaton’s new micro-military
circular connectors online. Furthermore, the company is providing a
cross-reference product guide on its website.
