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.[2] The connectors are particularly versatile and reliable, and due to their prevalence, relatively inexpensive.[3]
Many manufacturers have created connectors based on MIL-DTL-5015 and MIL-C-5015, for example Radiall-Van System. These connectors are available as off-the-shelf products for end users, as well as "mil-COTS" products for railway and military use.
