Application Scenarios
-
ROVs and AUVs (Unmanned Underwater Vehicles): Provides high-reliability power and telemetry feeds for 5-pin devices like thrusters, underwater lighting, and sonar arrays operating at extreme ocean depths.
-
Oceanographic Sensor Arrays: Delivers leak-proof signal transmission for CTD profilers, dissolved oxygen sensors, and environmental monitoring equipment deployed on long-term moorings.
-
Subsea Oil & Gas Field Equipment: Ensures corrosion-free, wet-mateable control connectivity for seabed monitoring pods, hydraulic valve actuators, and diver interface panels.
-
Commercial Diving Systems: Connects diver helmet cameras, external dive lights, and critical bi-directional communication lifelines back to topside consoles with absolute seal reliability.
Frequently Asked Questions
What does "wet-mateable" mean for these MCIL5M/F cable assemblies?
A wet-mateable connector allows you to connect and disconnect the assembly underwater or in wet, humid splash zones. The flexible Chloroprene rubber (Neoprene) sleeves squeeze out seawater as the connector pairs are mated, forming a watertight seal around the insulated contacts before electrical continuity is established.
Are these 5-pin connectors fully compatible with SubConn Micro Circular series?
Yes. Our MCIL5M and MCIL5F cable assemblies are manufactured to standard micro circular dimensional tolerances, making them 100% intermateable, drop-in replacements for standard SubConn connectors.
What cable jacket materials do you offer for harsh marine applications?
We offer both Polyurethane (PUR) and Neoprene jackets. For dynamic applications requiring extreme resistance to abrasion, tearing, and marine organism growth, we highly recommend our PUR jacket option.
What is the maximum depth rating for this assembly?
When properly mated, lubricated with dielectric grease, and secured, these cable assemblies are pressure-rated for up to 800 Bar, equivalent to a subsea depth of 8,000 meters.
What is the lead time and MOQ for custom underwater cable lengths?
As a direct OEM manufacturer, we support flexible MOQs for subsea equipment prototyping and mass production runs. Standard custom orders typically take 2 to 3 weeks, with expedited prototyping samples supported upon request.
Overview and Application Notes
Overview: Engineered for demanding deep-sea and subsea environments, the Micro Circular MCIL5M to MCIL5F 5-Pin Underwater Cable Assembly delivers uncompromised power and sensor signal integrity. Built with high-grade Chloroprene rubber (Neoprene) molding and industry-standard wet-mateable technology, this connector assembly provides leak-proof sealing under extreme hydrostatic pressures up to 800 Bar (8,000 meters depth). Featuring heavily gold-plated copper alloy contacts to resist saltwater corrosion, it serves as a direct drop-in alternative to standard micro circular connectors. As an experienced OEM/ODM manufacturer, EDOM Electronics offers fully customized cable lengths, heavy-duty PUR or neoprene jackets, and tailored pinout configurations to meet your specific ROV, oceanographic, and marine equipment requirements.
Application Notes:
-
Wet-Mating & Lubrication: Always apply a thin, even coat of approved dielectric silicone grease (e.g., Molykote 44 Medium) to the contact faces and internal rubber seals prior to mating underwater. This expels trapped seawater and maintains optimal insulation resistance.
-
Mating Key Alignment: Carefully align the raised indexing key on the male body with the keyway on the female receptacle before applying axial force. Never twist or bend the connectors during insertion or removal to prevent pin damage.
-
Cable Strain Relief: Avoid sharp bending directly behind the overmolded strain relief boot. Maintain a minimum bend radius of at least 10x the cable’s outer diameter to protect internal conductors and prevent delamination.
-
Locking Sleeves: For high-vibration dynamic applications or tidal zones, ensure a POM (Delrin) or stainless steel locking sleeve is securely installed over the mated connector collars to prevent accidental disconnection.
