DC10M Subsea Dummy Connector — Overview

The DC10M is a 10-contact Male dummy connector (protective cap) for the subsea circular connector series. It mates with any unmated 10-contact circular female connector — whether bulkhead or inline — to seal and protect the contact face during storage, transit, and deployment intervals when the working connector is not connected.

Constructed from the same chloroprene rubber and gold-plated contact materials as the working connectors, the DC10M maintains a rated seal pressure and protects contacts from biofouling, corrosion, and mechanical damage. It is an essential component for any subsea deployment program where connectors remain unmated for extended periods on the seabed or during surface handling.

Key Design Features

• Protective dummy cap for 10-contact male circular connectors — seals unmated connector faces against seawater ingress, biofouling, and mechanical impact
• Same chloroprene rubber construction as working connectors — rated to the same depth and temperature range, maintains seal integrity throughout long deployments
• Gold-plated contacts — preserves mating-face gold plating on the working connector by preventing galvanic contact with dissimilar metals during storage
• Keyed interface — aligns correctly to the working connector's keying pin, ensuring the dummy cannot be incorrectly installed
• Compatible with all 10-contact circular series bulkhead and inline connectors — universal protective solution across the entire 10-contact platform
• Rated beyond 500 mate/demate cycles — dummy connectors can be installed and removed repeatedly without degrading the working connector's contact face
• Essential for observatory and mooring programs — protects unused ports on junction boxes and instrument frames during unattended seabed deployments
• Available from 1 unit, standard 1–2 week lead time

Specifications

Typical Applications

• Protecting unmated 10-contact bulkhead connectors on ROV chassis during deck operations and transit
• Sealing unused junction box ports during long-term seabed observatory deployments
• Covering 10-contact inline connector faces during instrument storage and servicing intervals
• Protecting mooring instrument connector faces during surface preparation and deployment
• Sealing AUV payload connector ports between missions
• Providing corrosion protection for spare connectors stored in wet or humid environments
