As core equipment for underwater operations, submarines operate in extremely harsh environments: hundreds or even thousands of meters underwater generate enormous water pressure; complex marine corrosion challenges material toughness; alternating high and low temperatures and strong vibration directly affect equipment stability. Stable signal and power transmission are critical to ensuring the stealth and maneuverability of submarines. As the “lifeline” connecting various submarine systems, connectors directly determine the operational reliability of core systems such as electronic reconnaissance and power propulsion, thus imposing extremely high requirements for precision, high-pressure resistance, corrosion resistance and anti-interference capability.

With profound expertise in high-end precision connectors, Ankeno has accurately identified the core demands of the submarine sector. Its independently developed 01D Deep-Sea Metal Series Components, featuring customized design, exceptional environmental adaptability and stable transmission performance, have been successfully applied to multiple submarine models. They solve industry pain points such as easy leakage, signal distortion and short service life of connectors in deep-sea environments, making them the preferred high-reliability connection solution for submarines.

Ankeno 01D Deep-Sea Metal Series Components are specially designed for extreme deep-sea environments, including optical and electrical connectors of Metal D Series – Z-2HdYmEnSTK-R(P)SLm plug assemblies and HdYmEnSZJ-Lm socket assemblies. They enable efficient transmission of optical signals, electrical signals and power among core submarine systems, perfectly matching the connection needs of inboard and outboard equipment. Whether for signal interaction between outboard sensors and inboard control units or power supply for propulsion and electronic equipment, they provide stable and reliable connection support.

In response to the high-pressure underwater environment of submarines, this series demonstrates outstanding pressure resistance. The standard factory-tested transverse pressure reaches 45MPa, customizable up to 70MPa to suit submarines operating at different depths. Even under deep-sea high pressure, it effectively prevents seawater penetration and avoids connector damage or signal interruption caused by excessive pressure. This performance fully complies with stringent submarine electrical connector standards and is comparable to high-end international counterparts. Meanwhile, the components adopt a structurally superior sealing design, paired with polyurethane cables or rubber-sheathed cables, further enhancing underwater sealing reliability and ensuring stable operation in long-term immersion.

In material selection, the 01D Deep-Sea Metal Series fully addresses marine corrosion and environmental adaptability requirements for submarines. Standard models use highly corrosion-resistant 316L stainless steel, and higher-strength materials such as TC4 titanium alloy can be customized for special working conditions, effectively resisting seawater and salt spray corrosion and extending service life. The connector housing is made of 316L stainless steel, optical contacts use zirconia ceramic ferrules, and electrical contacts are gold-plated brass, ensuring structural strength while improving signal transmission stability and reducing contact resistance loss. Contact resistance is ≤10mΩ, insulation resistance ≥2000MΩ under normal conditions, and remains ≥1000MΩ even after rigorous environmental tests, effectively avoiding electromagnetic interference and ensuring the stealth of submarine communications.

Considering the differentiated needs of various submarine systems, this series features high customizability. The forms of plug and socket assemblies and cable lengths can be flexibly adjusted according to equipment installation space; internal contacts allow free combination, supporting three transmission modes: pure electrical, pure optical and optoelectronic hybrid, adapting to sonar, navigation, communication and other submarine systems. For example, in submarine sonar systems, the components achieve low-loss optical signal transmission: typical insertion loss at 1310nm is only 1.2dB, with low-loss versions reaching 0.35dB; at 1550nm, typical insertion loss is 1.0dB, with low-loss versions at 0.25dB, ensuring accurate transmission of sonar detection data and supporting underwater detection and navigation.

Furthermore, this series boasts excellent mechanical performance and environmental adaptability. Mechanical life is ≥1000 cycles, meeting long-term frequent mating requirements of submarines. The operating temperature ranges from -45℃ to 90℃, adapting to alternating low-temperature underwater and high-temperature equipment operation environments. Even under strong vibration, connections remain stable without loosening or signal interruption, fully complying with stringent submarine application standards.

In practical applications, Ankeno 01D Deep-Sea Metal Series Components have been successfully equipped on multiple conventional and special-purpose submarines, applied to core modules including propulsion, navigation, communication and sonar detection systems, achieving stable signal and power transmission and effectively improving submarine operational reliability. Compared with traditional connectors, this series not only solves connection challenges under deep-sea high pressure and corrosion but also reduces installation difficulty and maintenance costs through customized design, earning high user recognition.

As a leader in high-end precision connectors, Ankeno focuses on technological innovation, leverages the core advantages of the 01D Deep-Sea Metal Series, and continues to serve high-end equipment such as submarines by optimizing product performance and enhancing customized solutions. In the future, Ankeno will further address technical demands in the submarine sector, develop more reliable and precise deep-sea connectors, provide solid connection support for the upgrading of China’s submarine equipment, and promote the high-quality development of the underwater equipment industry.
