Key Features of the MCIL10M Underwater Connector
1. Compact 10-Pin Male Micro Circular Design
The MCIL10M incorporates 10 male electrical contacts in a compact circular connector interface.Compared with connectors featuring fewer contacts, its 10-pin configuration provides greater wiring flexibility for complex underwater equipment.Multiple electrical functions can be combined within one connector when the selected conductors, current levels, and signal requirements are compatible.Typical applications include:
- Multi-channel underwater sensor connections.
- ROV control and monitoring systems.
- AUV navigation modules.
- Marine data acquisition equipment.
- Underwater camera control circuits.
- Subsea instrumentation cables.
- Offshore monitoring systems.
Its compact construction is especially useful for equipment where available space is limited and multiple external connectors would increase system complexity.
2. Compatible with SubConn Micro Circular Connectors
The HYSF SUBSEA MCIL10M is designed as a compatible alternative to corresponding
SubConn Micro Circular 10-pin male inline connectors.Its mating interface is intended for compatible 10-pin female connector configurations.Recommended HYSF SUBSEA mating models include:
- MCBH10F: 10-pin female underwater bulkhead connector.
- MCIL10F: 10-pin female underwater inline cable connector.
This compatibility supports integration into existing subsea systems that use corresponding Micro Circular electrical interfaces.For replacement applications, the specific connector series, contact arrangement, mating geometry, and locking accessories should be checked against the original connector specification.The MCIL10M is manufactured by HYSF SUBSEA as a compatible product; it is not an original SubConn-branded connector.
3. Waterproof Molded Construction
The MCIL10M features a molded watertight connector body designed to protect electrical contacts and cable terminations from seawater ingress when correctly mated.Its marine-grade elastomer construction helps provide environmental protection around the electrical interface.The molded cable termination also supports strain relief, helping reduce stress concentration where the cable enters the connector body.Reliable underwater sealing depends on proper connector alignment, complete mating, appropriate retention, and the condition of the connector surfaces.For subsea installations, the complete mating assembly should be inspected before deployment.
4. Deepwater Performance up to 6,000 Meters
The HYSF SUBSEA Micro Circular connector family is designed for underwater applications with a stated maximum depth capability of up to
6,000 meters, corresponding to approximately
60 MPa of hydrostatic pressure.This makes the connector series suitable for demanding marine environments, including deepwater research, subsea monitoring, and underwater robotic systems.The final operating depth of an MCIL10M cable assembly depends on the complete system configuration.Important factors include:
- Mating connector compatibility.
- Cable construction and pressure suitability.
- Connector termination quality.
- Correct locking and retention.
- Installation procedures.
- Applicable pressure testing and qualification.
The stated depth capability applies to a properly configured and qualified mated assembly, rather than an exposed or unmated electrical interface.
5. Gold-Plated Male Electrical Contacts
The MCIL10M uses gold-plated electrical contacts designed to provide reliable electrical connection within the sealed mating interface.Gold plating helps maintain a conductive contact surface and provides resistance to contact-surface corrosion.This is particularly important for underwater electrical systems where signal quality and dependable circuit continuity are essential.The HYSF SUBSEA Micro Circular 10-pin series specifies a rated current of
5 A per contact.Actual allowable current must also account for cable conductor size, simultaneous contact loading, temperature conditions, and the approved assembly specification.
6. Flexible Cable Length and Wiring Options
The MCIL10M is typically supplied with a
1-meter cable as its standard inline configuration.Different cable lengths can be manufactured according to project requirements.Common examples include:
- MCIL10M with 1-meter cable.
- MCIL10M with 2-meter cable.
- MCIL10M with 3-meter cable.
- MCIL10M with 5-meter cable.
- MCIL10M with 10-meter cable.
- Custom-length subsea cable assemblies.
The connector can also be integrated into more complex cable assemblies with application-specific conductor assignments.Cable outer diameter, conductor size, shielding, and termination requirements should be confirmed before manufacturing customized assemblies.
