The IP68 Waterproof 7-Pin Male Female Flat Connector for Underwater Use is an IP68-rated flat underwater connector: the low-profile square head slots into narrow gaps where a round shell will not fit — slim ROV pods, sensor strips, edge-mounted instruments and cable-flat penetrations. 7-pin gold-plated contacts pass power and signal through one sealed penetration, and the flat mating face with O-ring keeps the joint watertight in service.

Product Highlights
- Flat, low-profile head: mounts in slim gaps, along cable runs and on flat surfaces where round connectors do not fit.
- IP68 sealing: O-ring face seal plus potted cable exit keep the dry side isolated from seawater.
- Square-flat machined body with marine-grade plating: compact square-flat construction for continuous immersion in salt water.
- Gold-plated contacts: stable contact resistance and corrosion resistance over long deployments.
- Plug, socket or mated pair: supplied as cable plug, bulkhead receptacle or ready-mated assembly.
- OEM/ODM: pin count, cable length, shell material and marking built to your drawing.

Structure & Sealing
Contacts are carried in a molded insulator inside the square-flat square-flat machined body with marine-grade plating. The flat mating face is sealed with an O-ring gasket, and the rear cable exit is potted; the threaded coupling nut clamps the pair together so the seal faces stay compressed under cable load. The flat geometry also resists rotation, keeping pin alignment stable across mating cycles.
Applications
- ROV / AUV slim pods and edge-mounted electronics
- Flat-surface sensor strips and underwater instrumentation
- Cable-flat penetrations on housings with limited depth
- Underwater robotics, marine exploration and monitoring equipment

- Cable length, jacket material and pigtail terminations to your drawing.
- Shell material options: brass, stainless steel 316L.
- 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 is the MOQ?
MOQ is 1 piece for trial orders; volume pricing is available on request.
Why a flat connector instead of round?
The low-profile square head fits slim gaps and flat mounting surfaces where a round shell cannot.
Can you build to my drawing?
Yes. Pin count, head 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; 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.
