MCILRA6M 6-Pin Male Right-Angle Inline Underwater Connector – Miniature Circular L-Type Series
Product Overview
The
HYSF SUBSEA MCILRA6M 6-Pin Male Right-Angle Inline Underwater Connector is a compact subsea electrical connector designed for underwater equipment requiring reliable multi-channel electrical connections and space-efficient cable routing.Belonging to the HYSF Miniature Circular Right-Angle Connector Series, the MCILRA6M features six male electrical contacts, a molded neoprene rubber body, and an integrated 90-degree L-shaped cable exit.Unlike conventional straight inline underwater connectors, its right-angle configuration directs the cable sideways from the connector mating interface. This design helps reduce installation clearance requirements and simplifies cable routing in compact underwater equipment.The six-pin configuration provides a practical electrical interface for multiple power, signal, control, and instrumentation circuits.The MCILRA6M is designed for demanding subsea environments, featuring IP68 waterproof protection and pressure capability up to
60 MPa (approximately 6,000 meters of seawater depth).Its construction combines gold-plated electrical contacts with a flexible neoprene rubber body, providing a practical connection solution for ROVs, AUVs, underwater cameras, marine sensors, subsea monitoring equipment, and marine robotic systems.The standard inline cable length is approximately
1 meter, with customized cable lengths, mounting specifications, and electrical configurations available according to project requirements.The MCILRA6M is particularly suitable for underwater equipment where connector dimensions, installation clearance, and controlled cable routing are important engineering considerations.
Key Features and Benefits
1. Six-Pin Male Electrical Configuration
The MCILRA6M features six male electrical contact positions arranged in a compact miniature circular connector interface.Its six-pin configuration allows multiple electrical circuits to pass through a single underwater connection.This helps simplify cable assemblies and reduces the need for several individual connectors.Typical applications include:
- Underwater sensor connections
- ROV control systems
- AUV navigation equipment
- Underwater cameras
- Marine data acquisition
- Subsea monitoring equipment
- Underwater lighting systems
- Marine robotic instrumentation
The male contact arrangement is designed to mate with the corresponding MCILRA6F female inline connector.The six contact positions provide flexibility for allocating power, signal, measurement, and control circuits according to the approved wiring diagram.
2. 90-Degree Right-Angle L-Shaped Cable Exit
One of the main advantages of the MCILRA6M is its integrated right-angle cable configuration.Its L-shaped design directs the cable approximately 90 degrees away from the connector mating axis.This is particularly useful when conventional straight inline connectors require excessive installation clearance.Key advantages include:
- Reduced axial installation clearance
- Controlled cable routing
- Improved integration in compact housings
- Reduced interference with adjacent components
- More organized cable management
- Greater flexibility in equipment layout
The right-angle configuration is especially beneficial for compact ROVs, AUV electronics, underwater sensor modules, and equipment with multiple closely spaced connector ports.For equipment manufacturers, this design provides additional flexibility when planning cable exits around pressure housings and mechanical structures.
3. Six-Channel Electrical Connectivity
Six electrical contacts provide practical connection capacity within a compact underwater connector.This makes the MCILRA6M suitable for systems requiring several independent electrical circuits through a single connection point.Depending on the approved wiring configuration, individual contacts can be allocated to:
- Sensor power
- Measurement signals
- Control circuits
- Auxiliary power
- Instrumentation
- Communication interfaces
Consolidating multiple circuits into one connector can simplify cable management and reduce the number of interfaces required on an underwater equipment housing.For sensitive signal applications, cable shielding, conductor arrangement, impedance, and electrical isolation requirements should be evaluated separately.
4. IP68 Waterproof Construction
The MCILRA6M features an IP68 waterproof design for demanding underwater applications.Its molded neoprene rubber body and precision connector construction support reliable sealing in marine environments.The IP68 specification identifies its protection against water ingress under applicable test conditions.For deep-water installations, the complete mated connector assembly must also meet the specified hydrostatic pressure requirements.
5. Deep-Sea Pressure Capability up to 6,000 Meters
The MCILRA6M is designed for underwater applications at pressures of up to
60 MPa, corresponding to approximately 6,000 meters of seawater depth.This makes it suitable for consideration in demanding deep-sea electrical systems.Potential applications include:
- Deep-water ROV systems
- Autonomous underwater vehicles
- Oceanographic research instruments
- Subsea monitoring systems
- Marine scientific equipment
- Underwater cameras
- Offshore inspection equipment
- Deep-sea sensor networks
The actual operating depth depends on the complete connector assembly, mating component, cable construction, sealing arrangement, and installation conditions.For critical applications, the complete mated assembly should be verified through appropriate hydrostatic pressure testing and engineering qualification.
6. Gold-Plated Electrical Contacts
The MCILRA6M features gold-plated electrical contacts designed for reliable electrical mating in underwater applications.Gold plating provides a conductive contact surface and helps reduce oxidation at the electrical interface.The contact construction supports suitable multi-channel power and signal connections.The electrical 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.
7. Flexible Neoprene Rubber Connector Body
The standard MCILRA6M features a molded neoprene rubber connector body.Neoprene is commonly used in underwater connector construction because of its flexibility and suitability for marine environments.Its molded construction supports the electrical contact assembly and cable entry while providing a compact and flexible connector structure.Key benefits include:
- Flexible rubber construction
- Compact connector geometry
- Suitability for marine environments
- Integrated cable support
- Practical installation and handling
- Resistance to routine mechanical wear
The connector body should be inspected periodically for cuts, cracks, deformation, and other visible signs of damage.
8. Standard One-Meter Cable and Customization
The standard MCILRA6M inline configuration is supplied with approximately
1 meter of underwater cable.This provides a practical cable length for many subsea instruments and underwater equipment assemblies.Customized cable configurations can be considered according to project requirements.Available customization options include:
- Alternative cable lengths
- Customized cable specifications
- Different conductor arrangements
- Customized wire identification
- Cable jacket options
- Customized electrical configurations
- Specialized cable termination requirements
For right-angle installations, cable exit orientation and minimum bending radius should be considered together when determining the final cable length and routing arrangement.
9. Designed for Compact Subsea Equipment
The MCILRA6M is particularly useful in applications where conventional straight connectors are difficult to install.Its 90-degree cable exit helps direct the cable away from nearby mechanical components and can improve the overall layout of compact equipment.Potential integration environments include:
- Micro-ROV electronics housings
- AUV sensor modules
- Compact subsea junction boxes
- Underwater camera assemblies
- Multi-port pressure housings
- Marine instrumentation packages
The right-angle configuration helps simplify cable routing without requiring additional external cable bends immediately behind the connector.
10. Miniature Circular Interface for Subsea Applications
