The Molex STII* connector series offers a versatile coupling nut design which allows the STII connector to provide either standard ST* or non-optical disconnect functionality. This STII series of connectors is made of the latest engineering polymers and metals. The series utilizes pre-radiused and pre-polished ceramic ferrules which minimize the polishing time and provide a consistent ferrule end face geometry. Employing the Molex termination method and the pre-polished connectors, consistent and economical terminations are readily achieved.

Connector-to-connector mating is achieved by using the standard ST bulkhead feed-through adapters. These adapters combine a molded polymer or metal housing with either the extremely precise ceramic, the rugged metal or the economical polymer alignment sleeve.
