The Durable Stainless Steel 7 Pin Female Coaxial Connector for Subsea Use is an IP68-rated coaxial underwater connector for RF, video and sonar links: a sealed coaxial penetration carries the signal from a subsea camera, sonar head or antenna to the surface without water in the path. It combines 7 contacts incl. coaxial channel (per model) in one sealed body.. The threaded coupling keeps the mating face watertight in service.

Product Highlights
- Sealed coaxial path: the RF / video signal crosses the housing wall through one IP68-sealed penetration.
- Stainless steel 316L housing: corrosion-resistant body for continuous immersion and salt-water service.
- Signal integrity: center-contact geometry matched to standard subsea coax cable; impedance on request.
- Compact or heavy-duty options: from mini camera links to heavy-duty towed-body and sonar feeds.
- Plug, socket or mated pair: supplied as cable plug, bulkhead receptacle or ready-mated assembly.
- OEM/ODM: cable type, length and termination built to your drawing.

Structure & Sealing
The coaxial center contact runs inside a molded insulator that holds the geometry stable under pressure; the outer shell of stainless steel 316l housing closes with an O-ring face seal, and the rear exit is potted directly onto the coax jacket so no screened length is left open to seawater. Mated, the seal faces compress and the signal path stays dry from camera to surface unit.





Applications
- Subsea camera and video systems
- Sonar heads and acoustic transducer feeds
- Underwater antenna and modem links
- ROV / AUV harnesses carrying RF or video through one penetration
Customization & OEM
- Coax type, impedance and termination matched to your cable.
- Hybrid layouts (power + coax) and pin counts built to order.
- Cable length, jacket material and pigtail terminations to your drawing.
- Laser marking and custom packaging for OEM programs.
Packaging & Delivery
Each connector ships 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 impedance is supported?
It depends on the cable type — send your coax specification and we will confirm the match.
Can you terminate to my cable?
Yes. Send the cable datasheet; pigtail or connectorised terminations are built to order.
Can you build to my drawing?
Yes. Contact layout, shell, cable and termination can be customized.
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 coax exit; each unit is pressure-checked before shipment.
How do you ship?
Express (DHL / FedEx / UPS / TNT) for small lots; air or sea freight for bulk orders.
