Product Overview

The HYSF SUBSEA MCILRA2M 2-Pin Male Right-Angle Inline Underwater Connector is a compact subsea electrical connector designed for underwater equipment requiring reliable two-circuit electrical connections and space-efficient cable routing.Belonging to the HYSF Miniature Circular Right-Angle Connector Series, the MCILRA2M features two male electrical contacts, a marine-grade 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 axial installation clearance and simplifies cable routing in compact underwater equipment.The two-pin configuration provides a practical electrical interface for power supply, signal transmission, and other suitable two-conductor electrical applications.Designed for demanding subsea environments, the MCILRA2M features 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 micro-ROVs, AUVs, underwater cameras, thruster systems, marine sensors, and subsea instrumentation.The MCILRA2M belongs to the Micro 2–8 Pin Right-Angle Series and uses a 7/16-20 UNF mounting thread.The standard inline cable length is approximately 1 meter, with customized cable lengths, conductor arrangements, and electrical configurations available according to project requirements.The MCILRA2M is particularly suitable for underwater equipment where connector dimensions, installation clearance, and controlled cable routing are important engineering considerations.

Key Features and Benefits

1. Two-Pin Male Electrical Configuration

The MCILRA2M features two male electrical contact positions arranged in a compact miniature circular connector interface.Its two-pin configuration provides a practical electrical connection for applications requiring two independent conductors.Typical applications include:

• ROV thruster power connections
• AUV auxiliary power
• Underwater camera power
• Marine sensor connections
• Pressure and temperature sensors
• Underwater lighting
• Subsea monitoring equipment
• Compact instrumentation modules

The male contact arrangement is designed to mate with the corresponding MCILRA2F female inline connector.The two contacts can be allocated to power or signal circuits according to the approved wiring diagram and electrical requirements.

2. 90-Degree Right-Angle L-Shaped Cable Exit

One of the main advantages of the MCILRA2M 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 micro-ROVs, compact AUVs, underwater camera housings, 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. Two-Channel Electrical Connectivity

Two electrical contacts provide a simple and compact connection interface for suitable power and signal applications.Depending on the approved wiring configuration, the contacts can be allocated to:

• Positive power supply
• Electrical return
• DC power connections
• Sensor signal circuits
• Auxiliary electrical connections
• Two-conductor instrumentation

The compact two-pin design helps reduce connector size and simplify cable assemblies.For higher-current applications, the conductor size, contact rating, cable temperature rise, and operating environment should be evaluated before selecting the final configuration.

4. IP68 Waterproof Construction

The MCILRA2M features an IP68 waterproof design for demanding underwater applications.Its molded marine-grade 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 MCILRA2M 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 MCILRA2M 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 male contact pins are designed to mate with corresponding female socket contacts while maintaining suitable electrical contact.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. Marine-Grade Neoprene Rubber Connector Body

The MCILRA2M features a molded marine-grade 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

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 MCILRA2M 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 thruster modules
• Compact subsea junction boxes
• Underwater camera assemblies
• Multi-port pressure housings
