As part of the HYSF SUBSEA Micro Circular connector series, the MCIL6M provides a dependable underwater cable connection solution for ROVs, AUVs, underwater cameras, marine sensors, oceanographic instruments, and offshore engineering equipment.<\/p>\n<p>Featuring six male electrical contacts, a compact molded body, and a waterproof mating interface, the MCIL6M is engineered for underwater applications where space efficiency, electrical reliability, and pressure resistance are essential.<\/p>\n<p>The connector is designed for subsea operating depths up to <strong>6,000 meters (60 MPa)<\/strong> in a correctly configured and qualified mating assembly. Its wet-mateable construction allows mating and unmating underwater when the appropriate operating and safety procedures are followed.<\/p>\n<p>The MCIL6M is compatible with corresponding 6-pin female Micro Circular underwater connectors, including the <strong>MCBH6F female bulkhead connector<\/strong> og <strong>MCIL6F female inline connector<\/strong>.<\/p>\n<p>Manufactured by <strong>HYSF SUBSEA<\/strong>, the MCIL6M 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 maintenance teams.<\/p>\n<h3>Key Features and Benefits<\/h3>\n<h4>1. Compact 6-Pin Micro Circular Design<\/h4>\n<p>The MCIL6M features a miniature circular connector design that accommodates six electrical contacts within a compact housing.<\/p>\n<p>Its small form factor makes it suitable for underwater equipment with limited installation space, including compact ROVs, autonomous underwater vehicles, subsea sensor modules, and underwater instrument packages.<\/p>\n<p>The six-contact configuration supports multiple electrical circuits within a single connector, helping reduce the number of separate underwater connections required.<\/p>\n<h4>2. SubConn-Compatible Mating Interface<\/h4>\n<p>The HYSF SUBSEA MCIL6M is designed for compatibility with corresponding SubConn Micro Circular 6-pin female connector interfaces.<\/p>\n<p>This allows customers to integrate compatible HYSF connectors into existing underwater equipment or use them as alternatives in new subsea electrical systems.<\/p>\n<p>The connector is also designed to mate with corresponding SEACON-style Micro Circular interfaces, subject to confirmation of the exact connector configuration.<\/p>\n<p>HYSF SUBSEA is an independent underwater connector manufacturer. The MCIL6M is a compatible alternative and is not an original MacArtney SubConn or SEACON-branded product.<\/p>\n<h4>3. Wet-Mateable Underwater Connection<\/h4>\n<p>The MCIL6M belongs to a wet-mateable underwater connector series designed for mating in marine environments.<\/p>\n<p>Unlike dry-mate-only connectors, which must be connected in dry conditions before immersion, a properly specified wet-mateable connector system can support underwater connection and disconnection procedures.<\/p>\n<p>This feature is particularly valuable for ROV maintenance, underwater instrument replacement, and subsea equipment operations.<\/p>\n<p>Electrical circuits should be de-energized before mating or unmating unless an explicitly approved live-mating procedure and rating are provided.<\/p>\n<h4>4. Deepwater Pressure Resistance<\/h4>\n<p>The HYSF SUBSEA Micro Circular series is designed for underwater applications up to 6,000 meters, corresponding to approximately 60 MPa of hydrostatic pressure.<\/p>\n<p>The MCIL6M provides a suitable connection solution for deepwater equipment when used with a compatible female connector and correctly installed retention components.<\/p>\n<p>The pressure capability of the complete assembly depends on the connector configuration, cable termination, mating interface, and installation conditions.<\/p>\n<h4>5. Marine-Resistant Molded Construction<\/h4>\n<p>The MCIL6M features a protective molded connector body designed for marine environments.<\/p>\n<p>The molding helps protect the electrical termination area while providing mechanical support between the connector and cable.<\/p>\n<p>Gold-plated mating contacts support stable electrical connections and help resist contact-surface corrosion during normal service.<\/p>\n<p>The connector&#8217;s compact construction makes it suitable for repeated handling during equipment deployment, inspection, and maintenance.<\/p>\n<h4>6. Six Electrical Contacts for Power and Signals<\/h4>\n<p>The MCIL6M provides six electrical contacts for applications requiring multiple low-power or signal circuits.<\/p>\n<p>The standard HYSF SUBSEA Micro Circular 6-pin series is rated at <strong>5 A per contact<\/strong>, subject to the specified cable, mating configuration, and operating conditions.<\/p>\n<p>Depending on system requirements, the six contacts may be assigned to sensor power, control signals, instrumentation interfaces, or other suitable electrical functions.<\/p>\n<p>Actual wiring assignments should be confirmed through an approved pinout drawing before production.<\/p>\n<h3>Tekniske spesifikasjoner<\/h3>\n<table>\n<tbody>\n<tr>\n<th>Parameter<\/th>\n<th>Spesifikasjon<\/th>\n<\/tr>\n<tr>\n<td>Manufacturer<\/td>\n<td>HYSF SUBSEA<\/td>\n<\/tr>\n<tr>\n<td>Model Number<\/td>\n<td>MCIL6M<\/td>\n<\/tr>\n<tr>\n<td>Product Type<\/td>\n<td>Underwater Inline Cable Connector<\/td>\n<\/tr>\n<tr>\n<td>Connector Series<\/td>\n<td>Micro Circular<\/td>\n<\/tr>\n<tr>\n<td>Antall kontakter<\/td>\n<td>6-Pin<\/td>\n<\/tr>\n<tr>\n<td>Contact Gender<\/td>\n<td>Male<\/td>\n<\/tr>\n<tr>\n<td>Compatible Connector Gender<\/td>\n<td>Female<\/td>\n<\/tr>\n<tr>\n<td>Mating Connectors<\/td>\n<td>MCBH6F, MCIL6F<\/td>\n<\/tr>\n<tr>\n<td>Protective Dummy Connector<\/td>\n<td>MCDC6F<\/td>\n<\/tr>\n<tr>\n<td>SubConn Compatibility<\/td>\n<td>Micro Circular 6-Pin Female Interface<\/td>\n<\/tr>\n<tr>\n<td>Mating Type<\/td>\n<td>Wet-Mateable<\/td>\n<\/tr>\n<tr>\n<td>Standard Cable Length<\/td>\n<td>1 Meter<\/td>\n<\/tr>\n<tr>\n<td>Custom Cable Length<\/td>\n<td>Available Upon Request<\/td>\n<\/tr>\n<tr>\n<td>Contact Material<\/td>\n<td>Gold-Plated Metal Contacts<\/td>\n<\/tr>\n<tr>\n<td>Rated Current<\/td>\n<td>5 A per Contact, Standard Series<\/td>\n<\/tr>\n<tr>\n<td>Operating Depth<\/td>\n<td>Up to 6,000 Meters<\/td>\n<\/tr>\n<tr>\n<td>Pressure Rating<\/td>\n<td>Up to 60 MPa<\/td>\n<\/tr>\n<tr>\n<td>Waterproof Design<\/td>\n<td>IP68, When Correctly Mated<\/td>\n<\/tr>\n<tr>\n<td>Primary Function<\/td>\n<td>Underwater Power and Signal Transmission<\/td>\n<\/tr>\n<tr>\n<td>Typiske bruksomr\u00e5der<\/td>\n<td>ROV, AUV, Sensors, Underwater Cameras, Marine Instrumentation<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><strong>Technical Note:<\/strong> Electrical ratings, cable conductor sizes, voltage capability, and pressure performance should be verified against the approved configuration and technical drawing before ordering.<\/p>\n<h3>Compatible Underwater Connectors<\/h3>\n<p>The MCIL6M is designed to mate with corresponding 6-pin female Micro Circular underwater connectors.<\/p>\n<h4>MCBH6F \u2013 6-Pin Female Bulkhead Connector<\/h4>\n<p>The HYSF MCBH6F is a female bulkhead-mounted underwater connector designed for installation on pressure housings, subsea junction boxes, underwater camera systems, and marine electronic enclosures.<\/p>\n<p>When paired with the MCIL6M male inline connector, it forms a detachable underwater electrical connection between an external cable assembly and equipment-mounted bulkhead interface.<\/p>\n<p>Typical applications include:<\/p>\n<ul>\n<li>ROV electronic pressure housings<\/li>\n<li>Underwater sensor modules<\/li>\n<li>Subsea junction boxes<\/li>\n<li>Marine monitoring equipment<\/li>\n<li>Underwater cameras and lighting systems<\/li>\n<li>Oceanographic instruments<\/li>\n<\/ul>\n<h4>MCIL6F \u2013 6-Pin Female Inline Connector<\/h4>\n<p>The HYSF MCIL6F is a female inline underwater cable connector designed to mate with the MCIL6M.<\/p>\n<p>This configuration supports detachable underwater cable-to-cable connections.<\/p>\n<p>It is suitable for subsea cable extensions, modular underwater equipment, instrumentation connections, and maintenance applications.<\/p>\n<p>Customers can specify cable lengths and wiring configurations according to their project requirements.<\/p>\n<h4>MCDC6F \u2013 Female Protective Dummy Plug<\/h4>\n<p>The HYSF MCDC6F is a female dummy connector designed to protect the exposed male mating interface of the MCIL6M when the working connector is disconnected.<\/p>\n<p>Using a suitable protective dummy plug helps reduce contamination and mechanical damage during equipment storage, transportation, and periods when the connector is not in use.<\/p>\n<h3>Typical Applications of the MCIL6M Underwater Connector<\/h3>\n<h4>1.
