Amphenol RJFC2B Connector Cap Receptacle Cover Assembly

Amphenol RJFC2B is a metal dust cap (cover) designed for RJF Series square flange receptacles, engineered to seal the open face of the receptacle whenever a mating plug is not installed, thereby preventing dust, moisture, and incidental contaminants from entering the connector interface during storage, transport, or idle periods. The cap comprises a metal body with a black finish and is specified to fit RJF Series square flange receptacles from the Amphenol Socapex RJF family, matching the standard flange pattern and ensuring compatible engagement with the corresponding receptacle features. Used as part of the RJF accessory lineup, the RJFC2B provides a durable, low-profile closure that protects the receptacle from environmental contaminants, supports long-term reliability of the RJF interface, and helps keep contact surfaces clean when the mating connector is removed. Officially cataloged as RJFC2B by Amphenol Socapex, this cap complements RJF square flange receptacles by offering a protective closure option for idle connectors, making it a practical addition for applications in industrial automation, telecommunications, and any deployment using the RJF series.
