-
Oceanographic Instrumentation: Provides reliable wet-mate connectivity for CTD (Conductivity, Temperature, Depth) sensors, ADCPs, and fluorometers, allowing for easy deployment and retrieval on research vessels.
-
Marine Renewable Energy: Ensures long-term, corrosion-resistant electrical connections for underwater control pods and sensors in offshore wind, wave, and tidal energy installations.
-
Commercial Diving Equipment: Integrates seamlessly into diving bells, underwater camera systems, and diver communication lifelines, ensuring absolute safety and signal integrity in harsh saltwater conditions.
Frequently Asked Questions
Can these connectors be mated and unmated underwater?
Yes. The MCBH/MCIL series are designed as wet-mateable connectors. The Chloroprene rubber construction and specialized contact design allow water to be expelled during the mating process, making them safe to connect and disconnect in wet or submerged conditions
Are these connectors compatible with standard SubConn micro circular connectors?
Absolutely. Our MCBH5M assemblies are engineered to exact industry specifications and serve as direct, drop-in replacements for standard SubConn micro circular connectors, offering 100% intermateability.
What is the maximum depth rating for this cable assembly?
When properly mated, lubricated, and installed, these cable assemblies are pressure-rated for up to 800 Bar, equivalent to a subsea depth of 8,000 meters.
Can you provide custom cable materials like PUR instead of standard neoprene?
Yes. As a direct OEM manufacturer, we can customize the cable jacket material based on your application. We offer Neoprene for excellent flexibility and PUR (Polyurethane) for applications requiring superior abrasion and cut resistance.
What is the minimum order quantity (MOQ) for custom lengths?
We support flexible MOQs for oceanographic researchers and subsea equipment manufacturers. Prototyping and custom length orders typically have very low MOQs. Please contact our engineering team with your specific requirements for a quick quote.
Overview and Application Notes
Overview: Engineered for severe subsea environments, the Micro Circular MCBH5M 5-Pin Underwater Cable Assembly provides flawless power and telemetry transmission for marine and oceanographic applications. Manufactured with high-grade Chloroprene rubber (Neoprene), these wet-mateable connectors ensure watertight integrity even at extreme depths up to 8000 meters (800 Bar). Designed as a drop-in replacement for industry-standard micro circular connectors, they feature precision-machined contacts with heavy gold plating to resist saltwater corrosion. As an experienced OEM/ODM manufacturer, EDOM Electronics offers fully customized cable lengths, specialized polyurethane (PUR) or neoprene jackets, and tailored pinouts to seamlessly integrate with your ROVs, AUVs, and underwater sensor networks.
Application Notes:
-
Wet-Mating & Lubrication: Always apply a thin layer of approved silicone grease (e.g., Molykote 44 Medium) to the contacts and sealing surfaces prior to mating to expel water and prevent O-ring degradation.
-
Mating Alignment: Ensure proper alignment of the indexing key before applying mating force. Do not twist the connector bodies during insertion or extraction, as this can damage the internal pins.
-
Cable Strain Relief: Avoid sharp bends directly at the overmolded boot. Maintain a minimum bend radius of 10x the cable outer diameter to prevent delamination between the cable jacket and the Chloroprene rubber mold.
-
Bulkhead Installation: When installing the mating bulkhead (MCBH5F) into a pressure vessel, ensure the mounting surface is clean, polished (Ra 0.8), and free of scratches to guarantee the O-ring face seal’s integrity under high pressure.
