Shanghai Kabel Intelligence Technology Co., Ltd deep sea stainless steel (316L) micro circular underwater connectors in 2-12 contacts, male and female. IP68+IP69K, 7000m depth. For long-term, tropical, and corrosion-critical deployments.
Shanghai Kabel Intelligence Technology Co., Ltd supplies a dedicated deep sea stainless steel variant of the Micro Circular underwater connector platform -- male and female, bulkhead and in-line, in 2 to 12 contact counts. The stainless steel (316L, electropolished) shell is specified for the most demanding subsea environments: full ocean depth deployments, extended long-term mooring campaigns, tropical and biologically active seawater zones, and mixed-metal ROV frames where galvanic corrosion is a primary design risk.
Rated to 7,000 m depth, IP68 sealed, SubConn® Micro Circular compatible.

All stainless steel shells are electropolished and passivated to maximize corrosion resistance. Threaded mating surfaces are treated to minimize thread galling -- a common failure mode when stainless steel threads are torqued repeatedly in seawater. An anti-galling compound is available on request for long-term deepwater deployments.

Yes. The stainless steel shell does not change the contact face or thread geometry. MCBH-SS mates with any MCIL of matching contact count, regardless of shell material.
Electropolishing removes surface irregularities and contamination from the stainless steel surface, creating a chromium-oxide passive layer that dramatically improves corrosion resistance -- especially important in high-salinity and biologically active seawater.
Yes. FKM (Viton) O-rings are available as an upgrade option for applications involving elevated temperature seawater or exposure to hydraulic fluids and oils. Specify when ordering.
Most contact counts (2-8) ship within 2-3 weeks. 10 and 12-contact may require 3-4 weeks. Contact sales@rovcable.com for current stock status.
