Subsea Wet-Pluggable Connectors

YingDiGe Subsea Wet-Pluggable Connectors are engineered for mission-critical underwater electrical connections that can be mated and unmated submerged in seawater without requiring system de-pressurization or surface recovery. Built as direct 1:1 drop-in replacements for standard SubConn® and SEACON® micro circular, circular, and low-profile series, our wet-mate connectors integrate seamlessly into existing underwater vehicles, subsea instrumentation, and oceanographic infrastructure.

Key Performance Features

  • Submerged Wet-Mating: Enables reliable underwater coupling and decoupling in seawater, rated for over 500 wet-mating cycles with superior insulation resistance (>200 MΩ).
  • Full SubConn® & SEACON® Interchangeability: Exact dimensional and pinout compatibility across bulkhead receptacles, in-line cable plugs, and field-attachable assemblies.
  • Extreme Deep-Sea Pressure Rating: Hydrostatically tested up to 800 bar (approx. 7,000 m / 23,000 ft operational depth) with an IP68/IP69K ingress protection rating.
  • Corrosion-Resistant Metallurgy: Premium AISI 316L stainless steel (standard), Grade 5 Titanium, or marine brass shells paired with heavy gold-plated copper alloy contacts for zero signal degradation.
