Micro Circular Straight Cable Plug Underwater Connectors -- 2 3 4 5 6 8 Pin | IP68 | 7000m Depth

Shanghai Kabel Intelligence Technology Co., Ltd supplies the full range of micro circular waterproof straight cable plug connectors (in-line type) in 2, 3, 4, 5, 6, and 8-pin counts. These are the MCIL series (Micro Circular In-Line) -- the cable-end wet-mateable plugs that connect to MCBH bulkhead receptacles installed in ROV housings, sensor enclosures, and subsea junction boxes.

All straight-body in-line connectors are rated to 7,000 m depth, IP68 sealed, and SubConn® MCIL compatible across all contact counts.

Full Model Matrix -- Straight In-Line Plugs

MCIL Male (pin contacts) mates with MCBH Female (socket contacts), and vice versa. Mixed mating with OEM SubConn MCIL/MCBH connectors is fully confirmed.

Frequently Asked Questions

What is the difference between MCIL Male and MCIL Female?

MCIL Male has pin contacts. MCIL Female has socket (barrel) contacts. MCIL Male mates with MCBH Female (socket bulkhead), and MCIL Female mates with MCBH Male (pin bulkhead). Specify clearly when ordering.

Can I order pre-terminated cable assemblies?

Yes. Specify cable OD, length, conductor cross-section, connector models at each end, and any overmold requirements. Factory-tested assemblies ship with a pressure test certificate.

Are these connectors compatible with SubConn MCIL?

Yes. Shanghai Kabel MCIL connectors are SubConn MCIL compatible -- they mate with OEM SubConn MCBH bulkheads in the field.
