The Underwater Micro Circular Connector Dummy for Rov Auv is a protective dummy plug for the micro underwater connector series. It seals the mating face of a receptacle or cable connector when the line is not in use, keeping seawater and debris out of the contacts, and shares the same sealed interface as the live connectors.

Structure & Sealing
The dummy plug carries no contacts: its sealed face replicates the mating geometry of the live connectors, so fitting it to an open receptacle restores the IP68 barrier. A lanyard or captive retaining cap can be supplied to keep it with the line.
Applications
- Capping unused receptacles on ROV / AUV harnesses
- Protecting spare connector faces during storage and transit
- Sealing bulkhead connectors on unmanned housings between dives
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.
