The Deep Sea High-Current Waterproof Underwater Connector 18 Pin Male Female Cable and Socket IP68 Standard 100-1500V5-50A is an IP68-rated high-current underwater connector for circuits that carry real power: thrusters, battery packs, high-output lights and winch drives. Thick-section gold-plated contacts and a sealed, corrosion-resistant body let it pass high current at low voltage drop without overheating in a wet housing.

Product Highlights
- High-current contacts: oversized gold-plated pins and sockets keep voltage drop and self-heating low under continuous load.
- IP68 sealing: O-ring face seal plus potted cable exit hold the dry side against seawater.
- Machined metal housing with marine-grade plating: corrosion-resistant body for continuous immersion and salt-water service.
- Heavy-gauge cable support: rear entry accepts large conductor sizes used on power feeds and thruster lines.
- Plug, socket or mated set: supplied as cable plug, bulkhead receptacle or complete mated assembly.
- OEM/ODM: pin count, cable gauge, shell material and marking built to your drawing.

Structure & Sealing
Power contacts sit in a molded insulator inside machined metal housing with marine-grade plating, spaced for the creepage distance a high-current circuit needs. Sealing is an O-ring face seal at the mating interface plus a potted cable exit at the rear; the threaded coupling nut clamps the pair under tension so the seal faces stay compressed while the cable is loaded.
Applications
- ROV / AUV thruster and manipulator power feeds
- Subsea battery packs, junction boxes and power distribution
- High-output underwater lighting and laser loads
- Winch, latch and actuator drives on marine equipment
Customization & OEM
- Pin count, contact size and current rating matched to your cable gauge.
- Cable length, jacket material and lug or pigtail terminations to your drawing.
- Shell material options: brass, stainless steel 316L; rubber over-molding for cable joints.
- 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 current can it carry?
The rating depends on pin count and cable gauge — send your load profile and we will confirm the configuration.
Can you supply a mated set?
Yes — plug, receptacle, bulkhead and ready-terminated cable assemblies can be quoted together.
Can you build to my drawing?
Yes. Contact size, shell, 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.
