Features & Benefits

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.
