Definition
According to semiconductorinsight a MIL connectors refer to electromechanical devices used to connect electrical circuits in demanding environments that require high reliability and ruggedness. They are designed in compliance with military standards (MIL-SPEC) such as MIL-DTL-38999, MIL-C-5015, MIL-DTL-26482, and others. These connectors are typically composed of metal shells, secure coupling mechanisms, and sealed contact arrangements to prevent ingress of moisture, dust, or electromagnetic interference.
