Application Scenarios
-
ROVs and AUVs (Unmanned Underwater Vehicles): Provides high-reliability power and telemetry feeds for thrusters, underwater lighting, and robotic manipulators operating at extreme ocean depths.
-
Oceanographic Sensor Arrays: Delivers leak-proof signal transmission for CTD profilers, ADCP current meters, and environmental monitoring equipment deployed on long-term ocean moorings.
-
Subsea Oil & Gas Field Equipment: Ensures corrosion-free, wet-mateable control connectivity for seabed monitoring pods, valve actuators, and diver interface panels.
-
Commercial Diving & Underwater Video Systems: Connects helmet cams, dive lights, and communication lines back to topside consoles with absolute seal reliability in saltwater environments.
Frequently Asked Questions
What does "wet-mateable" mean for the MCIL5F cable assembly?
A wet-mateable connector allows connection and disconnection underwater or in wet, humid splash zones. The flexible chloroprene rubber sleeves squeeze out seawater as the connector pairs are mated, forming a watertight seal around the insulated contacts before electrical continuity is established.
Is this connector fully compatible with SubConn Micro Circular series?
Yes. Our MCIL5 series cable assemblies are manufactured to standard micro circular dimensional tolerances, making them 100% intermateable drop-in replacements for standard 5-pin SubConn MCIL5F / MCBH5M / MCIL5M connectors.
What cable jacket options do you offer for harsh subsea applications?
Our standard assemblies feature highly durable Chloroprene rubber jackets (OD 7.9mm for 20AWG 5-conductor), providing extreme resistance to harsh subsea marine environments.
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 production runs. Standard custom orders typically take 2 to 3 weeks, with urgent prototyping samples supported upon request.
How do you test underwater cable assemblies before shipping?
Every single subsea cable assembly undergoes strict quality testing, including 100% pinout continuity checks, high-voltage insulation resistance testing, and hydrostatic pressure testing up to 800 bar to verify sealing integrity.
Overview and Application Notes
Overview: Engineered for demanding deep-sea and subsea environments, the Micro Circular MCIL5F / MCIL5M 5-Pin Underwater Cable Assembly delivers uncompromised power and sensor signal integrity. Built with high-grade chloroprene rubber molding and wet-mateable technology, this connector assembly provides leak-proof sealing under extreme hydrostatic pressures up to 800 Bar (8,000 meters depth). Featuring gold-plated brass or beryllium copper contacts housed in a rugged inline configuration, it serves as a direct drop-in alternative to industry-standard 5-pin micro circular connectors. As an experienced OEM/ODM manufacturer, EDOM Electronics offers customized chloroprene rubber cable lengths and tailored pin configurations to meet your specific ROV, oceanographic, and marine equipment requirements.
Application Notes:
-
Wet-Mating & Lubrication: Always apply a thin, even coat of approved silicone grease (e.g., Molykote 44 Medium) to the contact faces and internal rubber seals prior to mating underwater to expel trapped seawater and maintain insulation resistance.
-
Mating Key Alignment: Align the raised indexing key on the connector body before applying axial force. Never twist or bend the connectors during insertion or removal to prevent damage to the internal contact pins.
-
Cable Strain Relief & Routing: Avoid sharp bending directly behind the overmolded relief boot. Maintain a minimum bend radius of at least 10x the cable outer diameter to protect the internal conductors and overmold integrity.
-
Mating Locking Sleeve: For high-vibration dynamic applications, ensure the flexible POM or stainless steel locking sleeve is securely snapped into place over the mating connector collar.
