Key Features and Benefits

1. Ten Gold-Plated Female Electrical Contacts

The BH10F incorporates ten precision-manufactured female electrical contacts within a compact circular mating interface.Its ten-contact arrangement allows multiple electrical circuits to pass through a single bulkhead installation point.This configuration is suitable for applications involving:

• Multiple underwater sensor channels
• Electrical control signals
• Marine instrumentation
• Auxiliary power connections
• Subsea monitoring equipment
• Multi-core cable assemblies
• Underwater electronic modules

Gold-plated contact surfaces help maintain reliable electrical conductivity and reduce contact-surface oxidation.The female contact configuration is designed to mate securely with the corresponding IL10M male inline connector.

2. Marine-Grade 316L Stainless Steel Housing

The standard BH10F features a precision-machined 316L stainless steel housing, selected for demanding marine environments.316L stainless steel provides several advantages:

• Good resistance to seawater corrosion
• High mechanical strength
• Durability under external hydrostatic pressure
• Reliable threaded mounting
• Dimensional stability
• Suitability for deep-water equipment installations

The metal housing provides mechanical support for the electrical contact assembly and allows the connector to be securely installed through compatible enclosure walls.When the BH10F is installed in an aluminum housing, galvanic corrosion protection should be evaluated as part of the overall equipment design.

3. Designed for 6,000-Meter Water Depth

The BH10F is designed to operate at external hydrostatic pressures of up to 60 MPa, equivalent to approximately 6,000 meters of seawater depth.Its watertight construction is intended to maintain electrical isolation between the external marine environment and internal equipment circuits.This deep-water capability makes the connector suitable for:

• Deep-sea scientific instruments
• Underwater robotic vehicles
• Offshore inspection equipment
• Oceanographic monitoring systems
• Marine exploration platforms
• Subsea electronic enclosures

The complete installation must use the correct housing dimensions, sealing components, and assembly procedures to achieve the intended pressure performance.

4. SubConn and SEACON Compatible Interface

The HYSF BH10F is designed for compatibility with corresponding SubConn and SEACON Standard Circular underwater connector configurations.This compatibility makes it a practical option for customers requiring:

• Replacement underwater bulkhead connectors
• Compatible subsea cable interfaces
• Marine equipment maintenance
• Underwater system upgrades
• OEM subsea instrumentation
• Standardized electrical connections

For replacement applications, customers should verify the connector series, contact arrangement, mating gender, and installation dimensions before selecting the BH10F.

5. Wet-Mateable Underwater Connection

The BH10F belongs to HYSF SUBSEA’s wet-mateable Standard Circular connector family.When paired with the corresponding IL10M male inline connector, the interface is designed to support underwater mating and unmating.This capability is useful for subsea equipment that requires periodic maintenance, cable replacement, or modular system integration.Important: Electrical power should normally be disconnected before mating or unmating unless the complete connector assembly has been specifically qualified for energized operation.

6. Precision 5/8-18 UNF-2A Mounting Thread

The BH10F uses a 5/8-18 UNF-2A mounting thread for secure installation in compatible underwater equipment housings.The standard mounting configuration includes:

• Mounting Thread: 5/8-18 UNF-2A
• Nominal Thread Length: 19 mm
• Installation Type: Threaded Bulkhead
• Standard Housing Material: Acier inoxydable 316L

The threaded design supports secure panel mounting and accurate positioning of the connector within an enclosure.Before machining the equipment housing, the mounting hole dimensions, wall thickness, sealing surface, and installation clearance should be verified using the approved mechanical drawing.

7. Watertight O-Ring Sealing

The BH10F incorporates a bulkhead sealing arrangement designed to prevent seawater ingress through the connector mounting interface.O-ring sealing provides a barrier between the connector housing and the equipment panel.Proper sealing performance depends on:

• Correct O-ring dimensions
• Suitable sealing material
• Proper groove geometry
• Clean sealing surfaces
• Appropriate O-ring compression
• Correct installation procedures

Depending on the selected configuration, customized sealing arrangements may be available.For high-pressure equipment, the complete housing and bulkhead assembly should be validated under the intended operating conditions.

8. Standard 0.3-Meter Internal Wire Leads

The BH10F is normally supplied with approximately 0.3 meters of internal wire leads.These leads allow the bulkhead connector to be electrically connected to equipment inside the pressure housing.The standard pigtail arrangement simplifies integration into underwater electronic modules, marine instrumentation, and control systems.Available customization options may include:

• Longer internal wire leads
• Different conductor specifications
• Customized pin assignments
• Numbered wire identification
• Application-specific terminations
• OEM bulkhead connector assemblies

The actual wiring arrangement should always be confirmed against the supplied wiring diagram.

9. Optional Anodized Aluminum Housing

In addition to the standard 316L stainless steel construction, the BH10F may be supplied with an anodized aluminum housing.Aluminum configurations may be useful for underwater equipment requiring reduced weight or improved material compatibility with aluminum pressure housings.Material selection should consider:

• Operating depth
• Equipment weight requirements
• Corrosion protection
• Housing compatibility
• Mechanical strength
• Surface treatment
• Long-term seawater exposure

Custom housing materials and sealing arrangements are subject to technical review.
