The Amphenol SIM Connection System is a modular multifunctional, multipin rectangular connector in metallic or composite versions. Available in shielded and non-shielded versions, SIM connectors are qualifed to the EN-4165 specification.
The system consists of jam nut or flange mount receptacles, which can be assembled side-by-side on a panel. Plugs are available in standard or rack-and-panel versions in easily removable click-in modules. Two shell types are available: two modules and four modules. There are two mating types: push-pull and panel mount 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 six nuts and six keys that provide thirty-six keying combinations. Six color-coded nuts and keys can also be used to increase polarizing options.
The SIM is available in two series and two material versions:
