MCBH6M male bulkhead connector and
MCIL6M male inline connector.Manufactured by
HYSF SUBSEA, the MCIL6F is also designed for mating compatibility with corresponding MacArtney SubConn and SEACON Micro Circular connector interfaces, making it a practical alternative for subsea equipment manufacturers, marine engineering companies, and underwater system integrators.
Key Features and Benefits
1. Compact 6-Pin Micro Circular Design
The MCIL6F features a miniature circular connector design with six female electrical contacts arranged within a compact housing.This configuration provides an efficient solution for underwater equipment requiring multiple electrical circuits in limited installation space.Its compact structure is particularly suitable for small ROVs, autonomous underwater vehicles, marine instrumentation, underwater sensor packages, and subsea electronic modules.By integrating six electrical contacts into a single connector, the MCIL6F helps reduce the number of separate underwater connections required.
2. SubConn-Compatible Underwater Connector
The HYSF SUBSEA MCIL6F is designed for compatibility with corresponding SubConn Micro Circular 6-pin male connector interfaces.This compatibility allows the connector to be considered for replacement applications, equipment maintenance, and new underwater electrical system designs.The MCIL6F is also designed for use with corresponding SEACON-style Micro Circular connector interfaces, subject to confirmation of the exact mating configuration.HYSF SUBSEA manufactures compatible underwater connectors independently. The MCIL6F is not an original MacArtney SubConn or SEACON-branded product.
3. Wet-Mateable Underwater Connection
The MCIL6F belongs to the HYSF SUBSEA wet-mateable Micro Circular connector series.Wet-mateable connectors are designed to support connection and disconnection in underwater environments when operated according to the specified procedures.This capability is particularly beneficial for subsea equipment that requires periodic maintenance, sensor replacement, or modular connection changes.Unlike dry-mate-only connectors, which must be connected in dry conditions before immersion, a properly specified wet-mateable connection system supports greater flexibility during underwater operations.Electrical power should be disconnected before mating or unmating unless a specific live-mating procedure and rating have been approved.
4. Deepwater Pressure Resistance
The HYSF SUBSEA Micro Circular connector series is designed for underwater applications up to 6,000 meters, equivalent to approximately 60 MPa of hydrostatic pressure.When paired with a compatible male connector and properly installed retention hardware, the MCIL6F provides a suitable electrical connection interface for deepwater equipment.The operating depth of the complete cable assembly depends on the connector configuration, cable termination, mating interface, and installation requirements.
5. Durable Marine-Resistant Construction
The MCIL6F features a protective molded connector body designed for marine environments.Its molded construction helps protect the electrical termination area and provides mechanical support between the connector and cable.Gold-plated female contacts are used to support stable electrical performance and help resist contact-surface corrosion during normal service.The connector is designed for reliable use in marine conditions involving seawater exposure, underwater pressure, and repeated equipment handling.
6. Six Electrical Contacts for Power and Signals
The MCIL6F incorporates six female contacts for applications requiring multiple low-power or signal circuits.The standard HYSF SUBSEA Micro Circular 6-pin series has a nominal current rating of
5 A per contact, subject to the specified cable and operating conditions.Depending on the application, the six electrical contacts may be assigned to sensor power, control signals, instrumentation connections, or suitable communication interfaces.Wiring arrangements should always be verified against the approved pinout drawing before production.

MCIL6M – 6-Pin Male Inline Connector
The HYSF MCIL6M is a male inline underwater cable connector designed to mate with the MCIL6F.The two connectors can be used together in detachable subsea cable-to-cable assemblies.This arrangement is suitable for underwater cable extensions, modular sensor systems, marine instrument connections, and applications requiring removable cable sections.
MCDC6M – Male Protective Dummy Plug
The HYSF MCDC6M is a male dummy connector designed to protect compatible 6-pin female Micro Circular mating interfaces.When the MCIL6F is disconnected from its working male connector, an appropriate MCDC6M protective dummy plug can help protect the female contact interface from contamination and mechanical damage.This is particularly useful during transportation, equipment storage, maintenance, and underwater deployment preparation.
Typical Applications of the MCIL6F Underwater Connector
