Micro Circular Underwater Connector
Micro Circular Underwater Connector
"The Micro Circular Series is a cornerstone of subsea interconnect technology, specifically engineered for high-performance applications in the most demanding underwater environments. It is defined by its compact footprint and rugged reliability."
Subsea Circular Connector
Subsea Circular Connector
"The Circular Series is one of the most established wet-mateable connector lines in the marine industry. It is characterized by its larger diameter and thicker rubber molding, which provides superior mechanical strength and durability for long-term deployments."
Underwater Ethernet Series
Underwater Ethernet Series
"The Ethernet Series is specifically engineered to support high-speed data protocols (Cat5e, Cat6) in submerged environments. Unlike standard power connectors, these prioritize impedance matching and shielding to prevent data loss or interference under high hydrostatic pressure. They allow for a "
Subsea Coaxial Connectors
Subsea Coaxial Connectors
"The Coax Series features a specialized concentric design that maintains a constant characteristic impedance. It is essentially a subsea-grade coaxial interface that allows for the transfer of high-speed analog or digital signals while remaining completely wet-mateable and pressure-resistant."
Subsea Photoelectric Hybrid Connectors
Subsea Photoelectric Hybrid Connectors
"The Photoelectric Series combines the lightning-fast data transmission of Fiber Optics with the power-carrying capabilities of Electrical Contacts. This "
55 Series Underwater Connectors
55 Series Underwater Connectors
"55 Series Underwater Connectors & 55 Series Subsea Connectors"
Subsea Power Connectors
Subsea Power Connectors
"The Power Series consists of rugged, large-format connectors designed to deliver significant electrical energy to underwater systems. They feature oversized contacts and enhanced insulation to prevent arcing and thermal buildup. These are often used as the primary interface between a surface power supply and subsea distribution hubs."
Subsea Splitters & Y-Connectors
Subsea Splitters & Y-Connectors
"The Split Series underwater connector features a unique modular split-shell design, allowing for rapid field assembly and maintenance without compromising high-pressure integrity in extreme subsea environments"
Subsea Low Profile Connectors
Subsea Low Profile Connectors
"The Low Profile Series is engineered for subsea applications where space is at a premium. By significantly reducing the connector height and utilizing a right-angle cable exit, this series minimizes the footprint on instruments while optimizing hydrodynamic performance for moving platforms."
Subsea Metal Shell Connectors
Subsea Metal Shell Connectors
"The Metal Shell Series is designed for long-term subsea deployment where maximum durability and structural integrity are non-negotiable. Constructed from high-grade marine alloys, these connectors offer superior mechanical protection and reliable sealing in depths exceeding 7,000 meters."
Subsea Connector Accessories
Subsea Connector Accessories
"Our precision-engineered Nuts, Washers, and Locking Sleeves form the backbone of secure subsea connections. Designed to work in perfect synchronization with our connector series, these hardware components ensure structural integrity and leak-proof performance under extreme hydrostatic pressure."
Diving Connector-RMG/RMK
Diving Connector-RMG/RMK
"Our RMG and RMK series are the industry standard for commercial diving, providing robust, rubber-molded connections for diver comms and video systems."
