Key Features and Benefits
1. Compact 6-Pin Female Bulkhead Design
The MCBH6F features a miniature circular bulkhead design incorporating six female electrical contacts within a compact housing.This space-efficient configuration makes it particularly suitable for underwater equipment requiring multiple electrical connections within a limited panel area.Its compact construction is ideal for small ROVs, autonomous underwater vehicles, marine instrumentation housings, underwater sensor modules, and subsea electronic enclosures.The six-contact configuration allows multiple suitable electrical circuits to pass through a single bulkhead connection.
2. SubConn-Compatible Micro Circular Interface
The HYSF SUBSEA MCBH6F is designed for compatibility with corresponding SubConn Micro Circular 6-pin male connector interfaces.This makes it suitable for replacement applications, underwater equipment maintenance, and new subsea electrical system designs using compatible Micro Circular connectors.The MCBH6F is also designed for use with corresponding SEACON-style Micro Circular interfaces, subject to confirmation of the exact mating configuration.HYSF SUBSEA is an independent manufacturer of underwater connectors. The MCBH6F is a compatible alternative rather than an original MacArtney SubConn or SEACON-branded product.
3. Wet-Mateable Underwater Connection
The MCBH6F belongs to the HYSF SUBSEA wet-mateable Micro Circular connector series.Wet-mateable connectors are designed to support mating and unmating in underwater environments when operated according to the specified procedures.This capability is particularly beneficial for modular subsea equipment, underwater sensor replacement, ROV maintenance, and marine instrumentation applications.Electrical circuits should be de-energized 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 correctly mounted on an equipment housing and paired with a compatible male connector, the MCBH6F provides a suitable electrical interface for deepwater applications.The pressure capability of the complete installation depends on the bulkhead mounting arrangement, sealing system, mating connector, and operating conditions.
5. Marine-Grade Stainless Steel Housing
The MCBH6F is available with a marine-grade stainless steel housing designed for demanding seawater environments.Stainless steel construction provides mechanical strength and corrosion resistance, making the connector suitable for underwater equipment exposed to seawater and harsh operating conditions.The connector also incorporates gold-plated female contacts to support stable electrical performance and help resist contact-surface corrosion.Alternative housing materials or customized configurations may be reviewed according to project requirements.
6. Reliable Panel-Mount Installation
The MCBH6F features a threaded bulkhead mounting design suitable for integration into underwater pressure housings, instrument enclosures, and subsea junction boxes.The standard Micro Circular 2–8 pin series uses a
7/16-20 UNF-2A mounting thread, with installation dimensions defined in the corresponding technical drawing.The standard bulkhead connector is normally supplied with approximately 0.3 meters of internal wire leads.Mounting hardware and sealing components should be confirmed against the supplied product configuration and approved installation drawing.

MCIL6M – 6-Pin Male Inline Underwater Connector
The HYSF MCIL6M is a male inline underwater cable connector designed to mate with the MCBH6F female bulkhead connector.When connected, the two components form a detachable electrical interface between an external subsea cable assembly and an equipment-mounted bulkhead connector.This combination is suitable for underwater applications including:
- ROV electrical systems
- Underwater sensor modules
- Subsea junction boxes
- Marine monitoring equipment
- Underwater cameras and lighting systems
- Oceanographic instruments
The standard MCIL6M inline connector is normally supplied with a 1-meter cable, while the MCBH6F bulkhead connector typically includes approximately 0.3 meters of internal wire leads.Custom cable lengths and wiring configurations can be specified according to project requirements.
MCDC6M – Male Protective Dummy Plug
The HYSF MCDC6M is a male protective dummy connector designed to mate with compatible 6-pin female Micro Circular interfaces.When the MCBH6F is not connected to its normal working cable, an appropriate MCDC6M dummy plug helps protect the exposed female connector interface against contamination and mechanical damage.This is particularly useful during equipment transportation, storage, maintenance, and underwater deployment.
Compatibility with SubConn Micro Circular Connectors
