60 MPa (approximately 6,000 meters of seawater depth).With a compact Ø15.7 mm body and an approximate overall height of 39 mm, it is particularly suitable for ROVs, AUVs, underwater cameras, Gigabit Ethernet systems, subsea junction boxes, and high-density marine sensor installations.The MCBHRA8F is an ideal connector option for equipment manufacturers seeking to integrate multiple electrical channels while minimizing internal installation space.
Key Features and Benefits
1. Eight-Pin Female Electrical Configuration
The MCBHRA8F features eight female electrical contact positions arranged in a compact miniature circular connector interface.Its eight-pin configuration provides multiple electrical channels through a single bulkhead connection.Typical applications include:
- ROV control and instrumentation
- AUV communication systems
- Underwater cameras
- Gigabit Ethernet interfaces
- Marine sensor networks
- Sonar and hydrophone systems
- Subsea data acquisition
- Multi-channel control systems
- Underwater monitoring equipment
The female socket contacts are designed to mate with compatible eight-pin male connectors.The eight contacts provide flexibility for allocating power, signal, communication, and control circuits according to the approved wiring diagram.
2. Integrated 90-Degree Right-Angle Design
One of the main advantages of the MCBHRA8F is its integrated 90-degree right-angle configuration.The design directs the internal cable leads sideways instead of extending straight behind the bulkhead mounting interface.This is particularly useful when conventional straight bulkhead connectors require excessive internal installation clearance.Key advantages include:
- Reduced axial installation clearance
- Improved internal cable routing
- Better integration in compact pressure housings
- Reduced interference with nearby components
- More organized cable management
- Greater flexibility in equipment layout
The right-angle configuration is especially beneficial for compact ROV frames, AUV pressure housings, underwater camera modules, and multi-port subsea junction boxes.
3. High-Density Eight-Channel Connectivity
Eight electrical contacts provide substantial connection capacity within a compact bulkhead interface.Depending on the approved electrical configuration, the contacts can be allocated to:
- Power supply
- Electrical return
- Ethernet signal pairs
- Sensor signals
- Control circuits
- Auxiliary power
- Instrumentation
- Communication channels
The eight-pin configuration is particularly useful for systems requiring multiple electrical circuits through a single underwater interface.For Ethernet applications, the cable construction, shielding, impedance, pair allocation, and signal integrity must be verified against the required transmission speed.
4. 316L Stainless Steel or Anodized Aluminum Housing
The MCBHRA8F offers housing material options for different marine equipment requirements.
316L stainless steel provides corrosion resistance and mechanical strength for demanding subsea installations.
Anodized aluminum provides a lightweight alternative for equipment where overall system weight is an important consideration.Material selection should take into account seawater exposure, galvanic compatibility, pressure loading, mounting requirements, and the surrounding housing material.
5. Gold-Plated Brass Female Electrical Contacts
The MCBHRA8F features gold-plated brass female electrical contacts.Gold plating provides a conductive contact surface and helps reduce oxidation at the electrical interface.The female socket contacts are designed to receive corresponding male contact pins while maintaining suitable electrical contact.The mating surfaces should be inspected before installation and kept clean to prevent contamination from affecting contact performance.Correct alignment during mating is important to protect the electrical contacts and maintain reliable connections.
6. Dual O-Ring and Face-Seal Construction
The MCBHRA8F incorporates a dual O-ring and face-seal arrangement.This sealing configuration supports reliable waterproofing at the connector interface and bulkhead mounting area.Proper installation and mating are essential to maintain the intended sealing performance.The sealing surfaces should be inspected before installation and kept free from dirt, debris, and mechanical damage.For deep-water applications, the complete installed and mated assembly should be verified against the specified hydrostatic pressure requirements.
7. IP68 Waterproof Protection
The MCBHRA8F features IP68 waterproof protection for demanding underwater applications.Its precision housing, sealing arrangement, and electrical contact assembly are designed for subsea installation.For critical underwater systems, the complete connector and equipment assembly should be qualified according to the intended operating depth and installation conditions.
8. Deep-Sea Pressure Capability up to 6,000 Meters
The MCBHRA8F is designed for underwater applications at pressures of up to
