Our Underwater female connector Advantages:
The LINKHIVE W Series Underwater female connector is specifically developed for extreme underwater and marine conditions requiring resistance to high hydrostatic pressure — supporting depths of up to 300 meters (5 to 60 bar, depending on the socket type). These robust circular connectors use a threaded coupling mechanism to ensure watertight performance even during prolonged saltwater exposure.
With multiple keying options available, the W Series sealed receptacle enables dense multi-contact configurations while minimizing the risk of mismating. It is perfectly suited for mission-critical applications in offshore energy, subsea exploration, nuclear systems, chemical processing, marine instrumentation, and aerospace technology.
Wide range of insert configurations and shell sizes
Optional EMC shielding for signal integrity in harsh environments
Sealed receptacle Tested for field performance in real-world underwater deployments
Multiple mounting options to suit varied integration needs
IP68 circular plug socket
Designed for durability and precision, LINKHIVE W connectors provide a reliable interface for underwater systems that demand the highest standards in sealing and electrical performance.
