MCBH6M 6-Pin Male Bulkhead Underwater Connector – SubConn-Compatible Micro Circular Connector

The HYSF SUBSEA MCBH6M 6-Pin Male Bulkhead Underwater Connector is a compact, high-performance, wet-mateable electrical connector designed to provide reliable power and signal connections through underwater equipment housings. Engineered for demanding subsea environments, the MCBH6M offers a dependable waterproof bulkhead interface for ROVs, AUVs, underwater cameras, marine sensors, oceanographic instruments, and offshore engineering equipment.Featuring six male electrical contacts, a marine-grade stainless steel housing, and a compact Micro Circular mating interface, the MCBH6M combines space-saving construction with reliable electrical and mechanical performance.The connector is designed for underwater applications up to 6,000 meters (60 MPa) when correctly installed and used in a qualified mating configuration. Its wet-mateable interface allows underwater connection and disconnection when the appropriate operating procedures are followed.The MCBH6M is specifically designed to mate with corresponding 6-pin female Micro Circular underwater connectors, including the MCIL6F female inline underwater connector.Manufactured by HYSF SUBSEA, the MCBH6M 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 and marine engineering companies.

Key Features and Benefits

1. Compact 6-Pin Male Bulkhead Design

The MCBH6M features a miniature circular bulkhead design incorporating six male electrical contacts within a compact housing.This configuration provides an efficient solution for underwater equipment requiring multiple electrical connections through a limited panel area.Its compact structure is especially suitable for small ROVs, autonomous underwater vehicles, marine instrument housings, subsea sensor modules, and underwater electronic enclosures.The six-contact configuration helps reduce the number of individual bulkhead connectors required for suitable multi-circuit applications.

2. SubConn-Compatible Micro Circular Interface

The HYSF SUBSEA MCBH6M is designed for compatibility with corresponding SubConn Micro Circular 6-pin female connector interfaces.This allows customers to use compatible HYSF products in existing underwater connection systems or integrate them into new subsea equipment designs.The MCBH6M is also designed for use with corresponding SEACON-style Micro Circular mating interfaces, subject to confirmation of the exact connector configuration.HYSF SUBSEA is an independent underwater connector manufacturer. The MCBH6M is a compatible alternative rather than an original MacArtney SubConn or SEACON-branded connector.

3. Wet-Mateable Underwater Connection

The MCBH6M 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 the specified procedures are followed.This feature is particularly useful for ROV maintenance, underwater sensor replacement, modular subsea equipment, and marine instrumentation applications.Unlike dry-mate-only connectors, which must be connected in dry conditions before immersion, wet-mateable systems provide additional flexibility during underwater operations.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, corresponding to approximately 60 MPa of hydrostatic pressure.When correctly mounted on an equipment housing and paired with a compatible female connector, the MCBH6M provides a suitable electrical connection interface for deepwater applications.The operating depth of the complete system depends on the bulkhead mounting arrangement, sealing configuration, mating connector, and equipment installation requirements.

5. Marine-Grade Stainless Steel Housing

The MCBH6M is available with a marine-grade stainless steel housing designed for underwater service.Stainless steel construction provides mechanical strength and corrosion resistance, making the connector suitable for equipment exposed to seawater and challenging marine environments.Gold-plated male electrical contacts support stable electrical performance and help resist contact-surface corrosion.Alternative housing materials, including titanium configurations, may be reviewed according to project requirements.

6. Reliable Threaded Bulkhead Installation

The MCBH6M features a threaded bulkhead mounting design suitable for integration into underwater pressure housings, instrument enclosures, and subsea junction boxes.The standard HYSF SUBSEA 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 MCBH6M bulkhead connector is normally supplied with approximately 0.3 meters of internal wire leads.Mounting hardware and sealing components should be confirmed according to the supplied product configuration.

MCIL6F – 6-Pin Female Inline Underwater Connector

The HYSF MCIL6F is a female inline underwater cable connector designed to mate with the MCBH6M male bulkhead connector.When connected, the two components provide a detachable underwater electrical interface between an external subsea cable assembly and an equipment-mounted bulkhead connector.This combination is suitable for applications including:

• ROV electrical systems
• Underwater sensor modules
• Subsea junction boxes
• Marine monitoring equipment
• Underwater cameras and lighting systems
• Oceanographic instruments

The standard MCIL6F inline connector is normally supplied with a 1-meter cable, while the MCBH6M bulkhead connector typically includes approximately 0.3 meters of internal wire leads.Custom cable lengths and wiring configurations may be specified according to project requirements.

MCDC6F – Female Protective Dummy Plug

The HYSF MCDC6F is a female protective dummy connector designed to mate with compatible 6-pin male Micro Circular interfaces.When the MCBH6M is not connected to its working cable assembly, an appropriate MCDC6F dummy plug helps protect the exposed male contact interface against contamination and mechanical damage.This protection is particularly important during equipment transportation, storage, maintenance, and subsea deployment.

Compatibility with SubConn Micro Circular Connectors

The HYSF SUBSEA MCBH6M is designed for mating compatibility with corresponding MacArtney SubConn Micro Circular 6-pin female connectors.For mixed-brand installations, customers should verify the mating dimensions, contact arrangement, mechanical interface, and locking sleeve compatibility.
