Protect from vibration, shock, and moisture with MIL-DTL-38999 Mil Spec Connectors
MIL-DTL-D38999 is a popular and widely used subminiature circular connectors for military and aerospace applications. With three coupling methods, nine shell sizes, and a wide variety of contact arrangements, our MIL-DTL-38999 connectors help give you the range of choices you need. Moreover, the original aluminum Mil Spec connectors have evolved to include stainless steel and composite shells—supported by a range of finishes.
Mil-Spec connectors are built in accordance with military standards and are designed to handle the harshest environments. Mil specs have been written around specific applications and environments, such as the MIL-DTL-38999 cylindrical connector. Because Mil-Spec connectors are all housed under one umbrella, the user needs to determine the environment where the connector will live, considering temperature, humidity, shock and vibe, and exposure to corrosive chemicals like salt spray. The ease with which the boxes and cables can easily be connected and disconnected should also be considered. Mil-Spec connectors are used in rugged environments in applications that include automotive, mobile equipment, aerospace, oil, and gas.
Product Overview
MIL-DTL-38999 Connectors
The 38999 specification defines families of shells that intermate to provide protection from vibration, shock, and moisture. Inside the connectors are inserts that can be configured for a wide variety of contacts arrangements. MIL-DTL-38999 connectors are used to attach cables to one another or to electronics boxes in a wide variety of applications, including vehicles, ships, planes, and handheld equipment. They are also used in many non-military rugged applications like transportation and rugged equipment markets.
