MS5015 refers to the connector series complying with the U.S. military standard MIL‑DTL‑5015 (formerly MIL‑C‑5015), a specification covering heavy‑duty circular electrical connectors with crimp or solder contacts, widely applied in military and industrial fields.
The connectors are designed for rugged field use, and feature large profile knurlings for ease of handling, and anti-decoupling springs for maintenance-free performance. A complete range of pin sizes and insert arrangements are available.
