Key Features and Benefits of This Pin and Sleeve Plug

Where to Use the 16D33-UGY Pin and Sleeve Plug

This plug is well suited for industrial power connections and heavy-duty cable assemblies, where a detachable device speeds up connection and disconnection. Its NEMA 3R rating covers rain exposure, but it should not be treated as submersible.
