BH12M 12-Pin Male Bulkhead Underwater Connector \u2013 SubConn-Compatible 6000m<\/h1>\n

Product Overview<\/h2>\n

The HYSF SUBSEA BH12M<\/strong> is a 12-pin male bulkhead underwater connector designed to provide reliable electrical connections through subsea pressure housings, marine equipment enclosures, and underwater instrumentation panels.<\/p>\n

As part of the HYSF Standard Circular connector family, the BH12M combines a durable metal housing, twelve electrical contacts, and a sealed bulkhead mounting design for demanding underwater applications.<\/p>\n

The connector is primarily designed to mate with the IL12F 12-pin female inline underwater connector<\/strong>.<\/p>\n

Its twelve-contact configuration provides a practical solution for systems requiring multiple electrical circuits through a single enclosure opening.<\/p>\n

The BH12M can support suitable power distribution, equipment control, sensor connections, and instrumentation circuits within the electrical limits of the complete system.<\/p>\n

The Standard Circular series is rated for 550V AC\/DC<\/strong>, 10A per contact<\/strong>, and operating depths up to 6000 meters (60 MPa)<\/strong> when installed as part of an appropriately qualified assembly.<\/p>\n

The standard BH12M configuration features a 316L stainless steel housing<\/strong> and approximately 0.3 meters of internal wire leads<\/strong>.<\/p>\n

The connector is designed for mating compatibility with corresponding SubConn and SEACON Standard Circular interfaces.<\/p>\n

Typical applications include ROVs, AUVs, underwater sensors, sonar systems, offshore instrumentation, subsea monitoring equipment, and marine research platforms.<\/p>\n

Key Features and Benefits<\/h2>\n

1. Twelve Male Electrical Contacts<\/h3>\n

The BH12M features twelve male electrical contacts within a single circular bulkhead interface.<\/p>\n

This allows multiple electrical circuits to be routed through one connector installation.<\/p>\n

Depending on the approved electrical configuration, the contacts can be allocated to:<\/p>\n

    \n
  • Sensor power connections<\/li>\n
  • Equipment control circuits<\/li>\n
  • Instrumentation channels<\/li>\n
  • Monitoring signals<\/li>\n
  • Auxiliary electrical functions<\/li>\n
  • Suitable communication interfaces<\/li>\n<\/ul>\n

    The twelve-contact design can help reduce the number of individual enclosure penetrations required in complex subsea equipment.<\/p>\n

    Actual circuit allocation must account for voltage, current, conductor specifications, and signal integrity requirements.<\/p>\n

    2. Fixed Bulkhead Mounting Design<\/h3>\n

    The BH12M is designed for installation through the wall of a pressure housing or underwater equipment enclosure.<\/p>\n

    Unlike a cable-mounted inline connector, the bulkhead configuration provides a fixed electrical interface between the internal electronics and an external cable assembly.<\/p>\n

    Its threaded mounting arrangement enables mechanical installation into a properly machined enclosure.<\/p>\n

    The connector must be installed with the appropriate sealing components to maintain the integrity of the housing.<\/p>\n

    Correct mounting dimensions, sealing geometry, and thread specifications should always be verified using the approved drawing for the exact connector variant.<\/p>\n

    3. Marine-Grade 316L Stainless Steel Housing<\/h3>\n

    The standard BH12M uses a 316L stainless steel housing<\/strong>.<\/p>\n

    316L stainless steel is widely used in marine equipment because of its corrosion resistance, mechanical strength, and durability.<\/p>\n

    It is suitable for many seawater-exposed applications where the connector housing must withstand demanding environmental conditions.<\/p>\n

    Alternative housing materials, including anodized aluminum, may be available for specific configurations.<\/p>\n

    When selecting a connector for an aluminum enclosure, engineers should evaluate the risk of galvanic corrosion and select an appropriate installation method.<\/p>\n

    4. Wet-Mateable Connector Interface<\/h3>\n

    The BH12M belongs to the HYSF Standard Circular wet-mateable connector family.<\/p>\n

    It is designed to mate with the corresponding IL12F female inline connector.<\/p>\n

    Wet-mateable construction supports underwater connection and disconnection under the applicable operating conditions.<\/p>\n

    This is valuable for modular subsea equipment, underwater inspection tools, removable sensors, and marine research systems.<\/p>\n

    Important:<\/strong> Electrical power should be isolated before mating or unmating.<\/p>\n

    Wet-mateable does not automatically mean the connector is suitable for hot-plugging under electrical load.<\/p>\n

    5. Deep-Sea Pressure Capability<\/h3>\n

    The HYSF Standard Circular series is designed for operation at depths up to 6000 meters<\/strong>, equivalent to approximately 60 MPa<\/strong> hydrostatic pressure.<\/p>\n

    The BH12M provides a suitable bulkhead interface for deep-water applications when used with the correct mating connector and installation arrangement.<\/p>\n

    Overall pressure capability depends on the complete assembly, including:<\/p>\n

      \n
    • Bulkhead connector<\/li>\n
    • Enclosure wall<\/li>\n
    • Mounting seal<\/li>\n
    • Mating cable connector<\/li>\n
    • Electrical terminations<\/li>\n
    • Installation quality<\/li>\n<\/ul>\n

      All components must be suitable for the intended operating depth.<\/p>\n

      6. Gold-Plated Electrical Contacts<\/h3>\n

      The BH12M features gold-plated electrical contacts designed to provide stable electrical connectivity.<\/p>\n

      Gold plating helps reduce contact surface oxidation and supports reliable mating performance when the connector is properly maintained.<\/p>\n

      Contact reliability is especially important for underwater systems where repair and replacement may require significant time and operational resources.<\/p>\n

      7. SubConn and SEACON Compatibility<\/h3>\n

      The HYSF Standard Circular series is designed for mating compatibility with corresponding SubConn and SEACON Standard Circular configurations.<\/p>\n

      The BH12M can therefore be considered for compatible replacement applications and new subsea equipment designs.<\/p>\n

      Before installation, verify:<\/p>\n

        \n
      • Connector series<\/li>\n
      • Contact count<\/li>\n
      • Male\/female configuration<\/li>\n
      • Contact arrangement<\/li>\n
      • Mating dimensions<\/li>\n
      • Mounting thread<\/li>\n
      • Sealing requirements<\/li>\n<\/ul>\n

        A compatible mating interface does not automatically guarantee that the bulkhead will fit an existing panel opening.<\/p>\n

        8. Internal Wire Lead Configuration<\/h3>\n

        The standard BH12M is supplied with approximately 0.3 meters of internal wire leads<\/strong>.<\/p>\n

        These leads connect the bulkhead interface to the electrical equipment inside the pressure housing.<\/p>\n

        Custom lead lengths and termination arrangements can be configured for specific installation requirements.<\/p>\n

        The actual wire identification should be verified against the approved production drawing.<\/p>\n

        Installation note:<\/strong> The Standard Circular product range includes more than one 12-pin dimensional grouping. The mounting thread and installation dimensions must be confirmed against the drawing of the exact BH12M version before machining an enclosure.<\/p>\n

        Bulkhead Installation and Housing Sealing<\/h2>\n

        A bulkhead connector must provide reliable electrical connections while maintaining the environmental integrity of the equipment housing.<\/p>\n

        The BH12M is designed for installation through a machined opening in the enclosure wall.<\/p>\n

        Threaded Mounting<\/h3>\n

        The connector uses a threaded mounting arrangement.<\/p>\n

        The Standard 12\/16\/25-pin family documentation specifies a 3\/4-16 UNF-2A<\/strong> mounting thread and a nominal 25mm thread length<\/strong>.<\/p>\n

        These values apply to the referenced series configuration and should be verified against the exact product drawing.<\/p>\n

        The mating dimensions of different 12-pin connector variants should not be assumed interchangeable.<\/p>\n

        O-Ring Sealing<\/h3>\n

        The bulkhead sealing system helps prevent seawater ingress at the connector installation interface.<\/p>\n

        Effective sealing depends on:<\/p>\n

          \n
        • Correct O-ring selection<\/li>\n
        • Proper groove dimensions<\/li>\n
        • Suitable sealing surface finish<\/li>\n
        • Correct housing wall thickness<\/li>\n

                    3. Is BH12M compatible with SubConn?<\/h3>\n

                    The HYSF Standard Circular series is designed for mating compatibility with corresponding SubConn and SEACON configurations.<\/p>\n

                    Exact mechanical compatibility should be verified using the approved drawings.<\/p>\n

                    4. What is the depth rating?<\/h3>\n

                    The Standard Circular series is designed for depths up to 6000 meters under the applicable qualified installation conditions.<\/p>\n

                    5. What is the rated voltage?<\/h3>\n

                    The standard rated voltage is 550V AC\/DC.<\/p>\n

                    6. What is the rated current?<\/h3>\n

                    The rated current is 10A per contact.<\/p>\n

                    The wiring and complete cable assembly must also be suitable for the intended electrical load.<\/p>\n

                    7. What material is used for the housing?<\/h3>\n

                    The standard housing material is 316L stainless steel.<\/p>\n

                    The standard BH12M configuration includes approximately 0.3 meters of internal wire leads.<\/p>\n

                    9. What is the mounting thread?<\/h3>\n

                    The Standard 12\/16\/25-pin family documentation specifies 3\/4-16 UNF-2A.<\/p>\n

                    However, the exact BH12M mounting dimensions should be confirmed against the approved product drawing because multiple 12-pin dimensional configurations are listed within the wider Standard Circular range.<\/p>\n

                    10. Is BH12M wet-mateable?<\/h3>\n

                    Yes. The BH12M belongs to the HYSF wet-mateable Standard Circular connector family.<\/p>\n

                    Electrical power should be isolated before mating or unmating.<\/p>\n

                    11. Which dummy plug protects BH12M?<\/h3>\n

                    The corresponding protective accessory is DC12F<\/strong>, a 12-pin female dummy plug.<\/p>\n

                    12. Does BH12M include mounting accessories?<\/h3>\n

                    The standard bulkhead kit includes the specified mounting nut, washer, and O-ring according to the approved connector configuration.<\/p>\n

                    13. Can BH12M be installed in an aluminum housing?<\/h3>\n

                    Installation may be possible, but material compatibility, galvanic corrosion, sealing geometry, and mechanical requirements should be evaluated.<\/p>\n

                    14. Can BH12M support Ethernet?<\/h3>\n

                    The BH12M provides twelve electrical contacts, but compatibility with a specific Ethernet data rate is not guaranteed by contact count alone.<\/p>\n

                    Cable construction, impedance, shielding, and complete system performance must be verified.<\/p>\n

                    Why Choose HYSF SUBSEA BH12M?<\/h2>\n
