Heavy-Duty High Current Underwater Connector, Seacon Subconn Alternative with 2-8 Cores Customization

Product Overview： Our Heavy-Duty High Current Underwater Connector is specially developed for large-power underwater equipment under extreme marine harsh conditions. Designed with enlarged high-current contacts and reinforced pressure-resistant shell, it reliably carries heavy continuous load current without overheating or arcing. Multi-layer integrated compression sealing realizes IP68 full submersible waterproof performance to withstand deep-water hydrostatic pressure and long-term seawater immersion. Marine anti-corrosion alloy shell resists salt spray, seawater erosion and mechanical shock. Widely applied in ROV propulsion modules, subsea pumping equipment, offshore platform power distribution and other high-power underwater engineering projects. Custom pin layout, current rating and cable assembly are available on request.

Application field： Large ROV/AUV propulsion power modules and deep-sea working robots Offshore oil & gas, wind farm platform high-power distribution connection Subsea pumps, underwater hydraulic driving and heavy-duty underwater machinery Large-scale subsea monitoring

Product Description

Core Features

1. Heavy-Duty Oversized High-Current Contacts

Large-diameter solid copper contacts with heavy gold plating, excellent heat dissipation, ultra-low contact resistance, stable continuous high-current output under long-time heavy load without overheating. Mixed high-power + small signal pin layout is customizable.

2. IP68 Deep-Sea Watertight & High Pressure Resistance

Multi-stage composite rubber sealing + integral compression locking structure, completely prevent seawater infiltration. Reinforced mechanical structure bears deep submersion pressure, supports long-term 24-hour uninterrupted underwater operation.

3. Marine Grade Anti-Corrosion Rugged Housing

High-strength corrosion-resistant alloy housing passes strict salt spray, high-low temperature cycling and vibration tests, outstanding against seawater corrosion, biofouling and harsh coastal ambient environment.

4. Bayonet Quick Lock with Anti-Misplug Design

Twist bayonet locking enables fast on-site connection and disassembly; foolproof anti-reverse insertion avoids wrong assembly, over 1000 times durable mating cycles for frequent maintenance.

5. Full Customization Support
Customizable pin quantity, single-pin current, rated voltage, working depth, cable type and overmolded cable assembly to match unique high-power subsea equipment requirements.
