IP68 Waterproof Connectors & Adapters

Johnson / Cinch Connectivity Solutions IP68 Waterproof Connectors and Adapters feature the rugged TNC series that operates up to 11GHz and the SMA series that operates up to 18GHz. These products meet IP68 standards and are designed with internal gaskets along with an outer gasket. Waterproof in unmated conditions, these connectors and adapters are constructed for underwater applications, including mil-aero, transportation, oil and gas, and industrial Internet of Things (IoT). Johnson / Cinch Connectivity Solutions Adapters include hermetically sealed connectors to 1 x 10-8cc/sec, making them suitable for high-pressure vacuum applications and gas or liquid leakage prevention.
