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 terminations. 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 zirconia ceramic, the rugged phosphor bronze or the economical polymer alignment sleeve. *STII and ST are trademarks of Lucent Technologies
