MS3106 2812S PlugHole U.S. Military Standard Aviation Plug Connector A rugged, MILstandard circular plug designed for reliable power and signal connections in aviation and military applications. The MS3106 2812S plug offers a compact shell size and a defined contact arrangement for use where durability, secure coupling, and interchangeability with militaryspec hardware are required. Key benefits Reliable militarygrade connection: Engineered to the U.S. military standard for aviation connectors, providing a secure mating interface that resists vibration, shock, and accidental decoupling. Simplifies maintenance and replacement: Uses a standardized shell and contact arrangement so it mates with compatible MILseries receptacles and can be swapped into existing harnesses without special adapters. Compact, spacesaving design: Shell size 28 with the 12contact arrangement provides a balance between contact density and small footprint for tight installations. Durable in demanding environments: Built for frequent mating cycles and harsh field conditions encountered in aircraft, ground vehicles, and industrial systems. Key attributes Model: MS3106 2812S (plug) Type: U.S. Military standard aviation circular plug connector Shell size: 28 (compact shell for limitedspace installations) Contact arrangement: 12 positions (2812S configuration) Functionality: Provides a secure, keyed circular connection for combined power and signal wiring Compatibility: Mates with MILseries receptacles of the same shell size and contact arrangement; suitable for use in systems designed to MILDTL5015/MILspec interfaces Construction: Rugged metal shell with secure coupling; insulating insert to retain contacts and maintain correct polarization Performance: Designed for stable electrical contact, resistance to mechanical shock and vibration, and repeatable mating cycles Typical applications / use cases Aircraft and avionics: Wiring harnesses for avionics modules, cockpit instrumentation, sensors, and auxiliary systems where MILstandard connectors are required. Military and tactical vehicles: Power and signal connections in armored vehicles, communications shelters, and field equipment where rugged, standardized connectors ensure interoperability and field serviceability. Industrial and test equipment: Compact, durable connections for test benches, robotics, and industrial controllers that require a secure MILspec interface. Installation notes Ensure the mating receptacle matches the MS3106 2812S shell size and contact arrangement for correct compatibility. Follow standard crimping or soldering procedures for the specific contacts used; verify pin assignments before installation. Inspect seals and coupling threads (if present) for debris or damage prior to mating to maintain performance in harsh environments. This MS3106 2812S plug provides a compact, standardized solution for installations that require militaryspec reliability, secure mating, and straightforward compatibility with MILseries connectors.
