MIL-DTL-5015

MIL-DTL-5015 is a United States Military Standard which covers heavy-duty circular electrical connectors with soldered or crimped contacts.

[1] They are used for both digital and analog signals, as well as power distribution, and are common in various fields, including defense, aerospace, and industrial machinery.

During the late 1930s, Cannon's Type AN (Army-Navy) series set the standard for modern circular connectors,[5] and eventually in 1949, MIL-C-5015 was specified.

[8] Whilst the original military standard is no longer in use officially, the family of connectors continues to be called MIL-DTL-5015 or MIL-C-5015 by manufacturers and users.

Limited polarization is available in certain insert configurations, which relies on the pins bottoming out on the opposing connector face to prevent engagement.

Similar connectors with different contact arrangements and bayonet coupling rings are also available to military specifications.
