Currently in use with the largest US military contractors for mission critical systems, custom SIM plates have kept some of the most advanced US military hardware going for decades. Approved to EN4165, SIM is a rectangular, modular connector that is a proven alternative to the venerable D38999 circular. Available in either Metal, Composite or Plated Composite, SIM, with its broad range of plugs, receptacles, rear accessories, and modules is perfectly suited for harsh environment military applications. The product can be customized into several different configurations – scoop-proof, high density & mixed contacts all within a compact design. Custom designs can not only have value-added solutions such as PCBs but also can be structural members in your design.

Features & Benefits:

  • Application Specific - Connectors specific to your needs and designed by experts with decades of experience.

  • Connectorization - Multiple shell sizes and shapes that are used with the standard plugs. Designs can be structurally integral to the system.

  • Modularity - Flexibility in design (RF, Power, Signal, Fiber optic & Ethernet).

  • Shielded - High EMI shielding performances.

Sim Connectors

Military Avionics

Sophisticated interconnect systems to deliver greater power and speed to meet the requirements of modern and future flight applications.

Military Communications

Modern soldier kit is evolving to feature heads-up displays, advanced communications equipment, various types of optics, and more. Amphenol connectors are built to keep this gear online and working efficiently in even the harshest environments.

Military Rotorcraft / Helicopters

Sophisticated interconnect systems to deliver greater power and speed to meet the requirements of modern and future flight applications.

Military Vehicles

Amphenol connectors are lightweight and capable of handling extensive power transfers required for electric mobility vehicles and EV infrastructure.

While the future of military ground mobility is hybrid and electric vehicles, Amphenol connectors remain a mainstay in gasoline-powered, legacy combat vehicle systems.


Interconnect systems optimized for the extensive data transmissions that take place within modern missiles and guided munition systems during flight. Ruggedized products, optimized for performance and endurance in the world’s harshest environments, and engineered to achieve consistently exceptional performance.


Interconnect systems designed to meet the stringent electrical and connectivity requirements powering today’s advanced naval surface ships and submarines operating in littoral and deep water applications.


Unmanned vehicles, from unmanned aerial vehicles (UAVs), unmanned ground vehicles (UGVs), unmanned surface vehicles (USVs), and unmanned underwater vehicles (UUVs), are poised to conquer domains across land, air, and sea sooner rather than later. Amphenol connectors have the versatility to meet the requirements of unmanned applications operating in any space.
