MIL-DTL-5015 (MS310x / 97-series / CA-series) is the classic medium-to-heavyweight circular connector for power and control circuits on ground vehicles, generators, machine tools and marine equipment. Threaded coupling with five-keyway polarisation resists vibration-induced decoupling, and the solder-cup contact system handles the larger #16 and #12 wire gauges that signal-grade miniature connectors cannot.
