Custom High-Current Watertight Connector, Seacon/Subconn Equivalent 2-8 Pin for Deep Sea & Harsh Environments

Product Overview： Our Custom High-Current Watertight Connector is engineered for reliable heavy-power connection under wet, submerged, corrosive and high-vibration working conditions. Fully customizable in pin quantity, current rating, shell size and cable assembly, this heavy-duty waterproof connector adopts enlarged solid copper contacts to sustain large load current without overheating. Equipped with multi-layer compression sealing structure to achieve IP68 full submersion waterproof performance, the rugged alloy housing stands up to seawater erosion, dust ingress and wide temperature fluctuation. Widely used for subsea equipment, offshore machinery, industrial field devices and outdoor heavy-duty power systems where customized high-current wiring is required.

Application field： ROV/AUV subsea robots & underwater propulsion equipment Offshore wind power, oil & gas platform power connection Outdoor heavy machinery, construction & mining field devices Large industrial instruments and battery power modules

Product Description

Core Features

1. Full Customization on Demand

Flexible customization including pin number, single-pin rated current, voltage grade, shell structure, panel mount or cable overmolding. Custom design matches unique equipment circuit layout, avoiding redundant specification waste.

2. High-Current Thick Gold-Plated Contacts

Oversized solid copper contact with heavy gold plating delivers ultra-low contact resistance, excellent heat dissipation and anti-oxidation performance. Stable continuous high-current output without overheating or arcing for long-running heavy-load operation.

3. IP68 Reliable All-Round Waterproof & Dustproof

Multi-stage composite rubber sealing + locking compression design blocks water, moisture and fine dust completely. Available for splash, continuous immersion and shallow subsea working scenarios.

4. Rugged Housing for Harsh Environment

Marine-grade anti-corrosion alloy shell passes strict salt spray, shock and vibration testing. Outstanding resistance to humidity, chemical splash and temperature change, suitable for outdoor, coastal and industrial harsh conditions.

5. Quick Lock Structure & Long Service Life
Twist bayonet locking enables fast plug & unplug with anti-misplug protection; ≥1000 reliable mating cycles for frequent field maintenance and repeated connection.
