Ruggedized connectors deliver unparalleled performance in mission-critical military and aerospace applications
CDM Electronics, a premier authorized distributor of electronic connectors and cables, now stocks the latest generation of Eaton’s Micro-Military Circular Connector Series, which feature shell diameters as small as 0.43” (11 mm). The feature-packed series consists of fast-mating M1 (dual-start) and M5 (triple-start) connectors optimized for harsh environment applications ranging from command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR) to space flight. In addition to meeting all MIL-DTL-38999 performance and environmental requirements, the newly augmented parts are 40% smaller and 50% lighter than conventional MIL-DTL-3899 connectors, deliver higher contact densities, and incorporate redundant retainers and an epoxy bond to prevent insert movement within the shell. The parts are also intermateable with micro-miniature connectors from other manufactures, and a cross-reference guide is available on the CDM website.
Eaton’s Micro-Military Circular Connectors are delivered with application-specific performance modifications that include compliance to NASA low volatile condensable materials per ASTM E595. They also meet MIL-STD-810 for water immersion, their pin and socket crimp contacts meet MIL-C-39029, and their newly developed, high-density, application-specific insert patterns and proprietary coupling mechanisms further ensure robust interconnect engagement in high shock, vibration, and temperature fluctuation environments.
Specifically engineered to meet or exceed the stringent mechanical and electrical requirements of essentially all harsh environment military and aerospace applications, Eaton’s ruggedized connectors are ideally suited for military aircraft avionics, countermeasures, and weapons systems, as well as for commercial and private aircraft avionics, engine management systems, and in-flight entertainment systems. They are equally appropriate in space flight applications, missiles, and missile defense systems, along with air, land, and marine unmanned systems, and devices may also be specified in various C4ISR systems, including tactical communications radios, adapters, and accessories.
The circular connectors are now optimized for overmolding and supplied in shell sizes ranging from 6 – 12 with 1 – 26 contacts per connector. Dual-start M1 parts allow full mating in 1.5 turns, whereas triple-start M5 parts fully mate in one turn. The series’ copper alloy, gold-plated 23AWG contacts are rated 5A each with a contact retention of 15lbs, while its 16AWG contacts are rated 13A each with a contact retention of 25lbs. M1 and M5 parts feature mating/unmating cycles of 2000 and 500 cycles, respectively, and their insulation resistance (IR) is 5,000MΩ minimum. The connectors are offered as plugs and receptacles in inline, jam nut, and square flange formats, and their aluminum shells may be ordered with RoHS-compliant electroless nickel or in cadmium/olive drab finishes rated to withstand 500 hours of salt spray. Value-added cable and wire harness assemblies are also available.
