Mencom now offers their classic port adapters in a low profile black plastic shell with a M25 mounting thread. They are rated IP65, which means they provide total protection against dust and jets of water from all directions. These new plastic port adapters offer a substantial savings compared to the metal versions.
These port adapters have a RJ45, USB Type A, or USB Type B connector potted inside the plastic shell, and can easily be mounted to a cabinet through a 1” diameter hole. They are supplied with a cap tethered to the connecter via a TPE gasket that not only clutches the cap, but also works as a waterproof washer.
