Cybersecurity Caps are a rugged composite locking system which prevents a cap from being uncapped or a plug from being unmated from its receptacle. They are solutions that prevent connector tampering. Cybersecurity is achieved through a combination of precautions. One way to reduce the risk of opportunity intrusion into the electronics through the connectors is by adding locking devices.

Features & Benefits:

  • CapLock is a locking ring that allows a Cap to lock onto a receptacle to secure the port access. Once locked around the cap, Caplock turns freely around the cap and prevents fingers from unlocking it

  • PlugLock is a locking ring that allows a plug to lock onto a receptacle to secure the plug to receptacle connection. Once locked around the plug coupling nut, Pluglock turns freely around it and prevent the fingers from unlocking it.

  • Metal CapLock is a Cap for receptacle that includes a coupling nut which can be activated or desactivated using a specific locking screw.

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.
