MS5015 / MS3102A365P 4 Core 4Pin U.S. Military Standard Aviation Plug & Socket Docking A professionalgrade circular aviation connector set designed to provide a reliable, compact 4‑core connection that matches U.S. Military Standard form factors. Ideal when you need a secure, repeatable electrical interface for aircraft, defense, and industrial equipment. Key benefits Reliable mating and retention: Secure plugtosocket docking minimizes accidental disconnection during operation and handling. Standardized compatibility: Built to the MS3102A/MS5015 form factor so it mates with equipment and harnesses that use the same military specification. Simplifies system integration: Four conductors in a single compact connector reduce wiring bulk and speed installation and maintenance. Clear function separation: Fourpin layout supports straightforward signal/power distribution with easy identification during assembly.
