The Amphenol MS3450 MIL-DTL-5015 Rear-Release Threaded (Matrix®) series connectors use rear-release crimp contacts with a retention clip. These Amphenol MS3450 connectors fill the gap between older MIL-DTL-5015s and the environmental and higher-performance needs of new technologies. These MS3450 connectors are sealed to withstand moisture, condensation, vibration and flash-over. Over 165 contact layouts are available, in variations that allow for just power, just signal, or a mix of both contact types. These were formerly MIL-C-5015.
