The SIM is a Modular, Rectangular, Multicontact, and Multifunctional connector.
It’s available in metallic or composite versions, shielded or unshielded, and qualified according to the EN 4165 spec. It consists of standard or flanged mount receptacles that can be assembled side by side on a panel, standard or rack and panel plugs with easily removable click-in modules. Two shell types are available: 2 modules and 4 modules. There are two mating types: clicker nut and rack panel plug. When mating the plug to the receptacle, polarization is mechanically ensured by an asymmetrical mounting screw. The coupling screw includes a polarizing system with 6 versions of hexagonal nuts and keys, providing 36 keying combinations. The shielded versions (SIM 2D and SIM 2B) provide an shielding effectiveness of 50 dB at 100 MHz and 30 dB at 1 GHz. A broad range of rear accessories (covers and cable clamp) complete the connectors.The SIM connector is fully intermatable with connectors complying with standards MBBN 3330 and EN4165.

Features & Benefits:

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

  • Rectangular -Space efficiency due to compact design, more power in less space.

  • Sealed - Excellent performances due to silicon overmolding process that meets or exceeds IP66 / IP68 / IP69K.

  • Shielded - High EMI shielding performances.

  • Comes in Metallic or Composite versions (weight saving).

  • Fire/Smoke/Toxicity conform to ABD0031 and FAR 25853

  • Corrison Resistance: tested up to 500hrs of salt spray, available in Olive Drab Cadnium, Bright Nickel, Black Nickel.

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.


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.


Amphenol connectors in everything from low Earth orbit (LEO) satellites that make advanced communications and our modern digital world possible, to the International Space Station and other spaceborne applications. Amphenol connectors have been relied on for decades to ensure manned and unmanned space vehicles stay online, allowing astronauts and aeronautical agencies to complete their missions operating in the harshest environment known to man.


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.
