The Mcbh8f+Mcil8m Subconn Compatible Connector Male & Female Waterproof Subsea Marine & Deep Sea is an IP68-rated micro circular connector for subsea vehicles and instruments. Multi-pin gold-plated contacts pass power and signal through one sealed penetration, and the threaded coupling nut keeps the mating face watertight in service. The bulkhead pattern mounts through a housing wall: the wet side mates outside, the dry side is wired inside.

Structure & Sealing
Contacts are carried in a molded insulator inside machined metal housing with marine-grade plating. Sealing is achieved by an O-ring face seal on the mating interface and a potted cable exit on the rear; the threaded coupling nut holds the pair together under tension without tools. When mated, the seal faces compress so the wet-side circuit stays isolated from the dry-side housing.
Applications
- ROV and AUV harnesses, manipulator and tooling interfaces
- Subsea sensors, cameras, sonar and imaging heads
- Oceanographic, geotechnical and environmental monitoring instruments
- Underwater lights, thrusters, actuators and pressure housings
Customization & OEM
- Pin count, contact type (power / signal / coax hybrid) and shell size built to order.
- Cable length, jacket material and pigtail or connectorised terminations to your drawing.
- Shell material options: brass, stainless steel 316L, titanium alloy; PEEK or rubber over-molding.
- Laser marking and custom packaging for OEM programs.
Packaging & Delivery
Each connector ships in an ESD-safe bag with a protective cap on the mating face, packed in a foam-lined export carton. Lead time depends on configuration and quantity — contact us for a current schedule. DHL / FedEx / air / sea freight supported.
FAQ
What is the MOQ?
MOQ is 1 piece for trial orders; volume pricing is available on request.
Can you supply a mated pair?
Yes — male plug, female receptacle, bulkhead and cable assemblies can be quoted as a set.
Can you build to my drawing?
Yes. Pin count, shell size, cable and termination can be customized; send your drawing for a proposal.
What is the lead time?
It depends on stock and customization level — contact us with your configuration for a firm date.
How is the connector sealed?
An O-ring face seal plus a potted cable exit; hermetic versions add a glass-to-metal seal.
How do you ship?
Express (DHL / FedEx / UPS / TNT) for small lots; air or sea freight for bulk orders.
