Thyez, France, December 9, 2022 – With the ever-increasing threat of cyberattacks across the world, it is crucial to keep systems safe and secured from attackers, no matter the origin of the source. While keeping strong passwords and changing them frequently is one of the most efficient ways to strengthen cybersecurity, other risks remain. Systems can also be breached through connectors.

Aware of this issue, Amphenol SOCAPEX has developed a locking solution for 38999, RJFTV, USBFTV connectors and caps series. Locks ensure additional security by reducing the risk of manual unlocking of plugs and caps, thereby limiting deliberate intrusions through connectors.

The new line includes CapLock, PlugLock and Metal CapLock solutions.

CapLock is a locking ring that prevents direct access to the cap mounted on a receptacle to secure access to the port. Once the Caplock is installed, it rotates freely around the cap and prevents it from being manually unlocked.

PlugLock is a ring that prevents intrusion on a port by locking the connection between the plug and thereceptacle. Once installed around the coupling nut of the plug, PlugLock rotates freely around it, preventing manual unlocking.

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

Key Features: 

CapLock and PlugLock
