Amphenol MS3450 Series Connectors  (MIL-DTL-5015)


HIGH-PERFORMANCE ALTERNATIVE TO OLDER MIL-DTL-5015 SOLDER TYPES

The Amphenol MS3450 MIL-DTL-5015 Rear-Release Threaded (Matrix®) series connectors use rear-release crimp contacts with a retention clip. These Amphenol connectors fill the gap between older MIL-DTL-5015s and the environmental and higher-performance needs of new technologies. They 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. For more detailed product information on MS3450 series connectors, please see the specifications below.

FEATURES

AMPHENOL MS3450 SERIES FEATURES

  • Broad Operating Temperatures
    The electroless nickel plating and stainless steel shell connectors will operate in temperature ranges from -75°F to +392°F (-55°C to 200°C). The cadmium olive drab plating connectors will operate in temperatures ranging from -75°F to +347°F (-55°C to 175°C).

  • Environmental
    These connectors will perform in the full range of operating conditions defined in MIL-DTL-5015 and are recommended for conditions where vibration, moisture, pressure, and/or temperatures are extreme.

  • Rugged Shell
    The rugged aluminum alloy or steel shell are highly resistant to damage and corrosion with firewall capabilities. Shells are available in four different styles, like a self-locking coupling nut in seventeen different sizes.

  • Wide Range of Wire Gauges and Current-Carrying Capacity
    Up to 150 amps for standard military contacts and wire gauges from size 20 to size 0 AWG.

* Each insulator has a specific service rating. These numbers should be used by the designer only as a guide. The Service Ratings for each layout are listed on here.

† Not corrected for change in density resulting from variations in temperature.

MS connectors show no evidence of breakdown when the given test voltages are applied between the two closest contacts and between the shell and the contacts closest to the shell for a period of one minute, per MIL-STD-1344 Method 3001.
