Micro Circular Underwater Connectors -- MCBH MCIL Series Full Range | IP68 | 7000m | SubConn Compatible

Shanghai Kabel Intelligence Technology Co., Ltd supplies the complete Micro Circular underwater connector platform -- MCBH (bulkhead) and MCIL (in-line) types -- in all standard contact counts from 2 to 21, plus right-angle (MCBHRA), stainless steel, and titanium shell variants. This is the most widely deployed subsea wet-mateable connector platform globally, used across ROV systems, AUVs, oceanographic instruments, and offshore oil and gas infrastructure.

All connectors are rated to 7,000 m depth, IP68 sealed, PEEK insulated, and directly compatible with SubConn® MCBH/MCIL series connectors.

Frequently Asked Questions

Are all Shanghai Kabel Micro Circular connectors SubConn compatible?

Yes. All MCBH and MCIL models are manufactured to SubConn-compatible face geometry and thread dimensions for every contact count.

How do I choose between aluminium, stainless steel, and titanium shells?

Aluminium is lightest and most cost-effective for standard deployments. Stainless steel (316) suits long-term or tropical deployments. Titanium suits high-performance ROV frames where weight is critical and galvanic compatibility with carbon fibre is required.

Do you supply complete cable assemblies?

Yes. Specify cable OD, length, conductor spec, and connector models. Factory-tested assemblies with pressure test certificate available for all contact counts.
