8 Pin Micro Circular Underwater Connector -- MCBH8F & MCIL8M | IP68 | 7000m | SubConn Compatible
Shanghai Kabel Intelligence Technology Co., Ltd supplies 8-contact micro circular wet-mateable underwater connectors including MCBH8F (bulkhead female) and MCIL8M (in-line male) -- the most widely used high-contact-count configuration in the standard Micro Circular platform. 8 contacts provide the maximum conductor count in a compact Micro Circular housing before stepping up to the larger 10/12/16-contact series.
Rated to 7,000 m depth, IP68, SubConn® MCBH8/MCIL8 compatible.
Available Models -- 8 Contact

Frequently Asked Questions
Does MCBH8F mate with SubConn MCIL8M?
Yes. Shanghai Kabel MCBH8F mates directly with OEM SubConn MCIL8M -- identical contact geometry and thread dimensions.
When should I choose 8-contact vs 10-contact?
8-contact fits within the standard compact Micro Circular housing. If you need more conductors and can accept a slightly larger housing, the 10-contact or 12-contact variants are available. 8 contacts is typically the sweet spot for camera, lighting, and dual-bus sensor assemblies.
Is a right-angle 8-contact connector available?
Yes. MCBHRA8M and MCBHRA8F are available for space-constrained panel installations.
