Standard 2-5 Pin Watertight Connectors

Product Overview & Series Introduction

Сайт Standard 2-5 Pin Watertight Connectors series by HYSF Subsea (Xiamen Chuida Technology Co., Ltd.) represents the global industry benchmark for robust, wet-mateable power and signal distribution systems. Engineered specifically for relentless, long-term submersion in high-pressure marine and oceanographic environments, this deep-sea rubber series delivers uncompromised electrical integrity and flexible layout termination options to achieve domestic substitution for imported core products and provide absolute mission-critical reliability.

Every connector configuration features heavy-duty gold-plated copper contacts housed within premium high-temperature vulcanized neoprene rubber bodies. To accommodate complex structural layouts on subsea hulls, instrumentation enclosures, and pressure chambers, the standard series provides a comprehensive array of physical form factors, including:

• Cable Solutions: Standard Male/Female inline cables (IL2M to IL5F) and right-angled, space-saving L-shaped variants (ILRA2M to ILRA5F).
• Bulkhead Feedthroughs: Threaded receptacles (BH2M to BH5F) paired with premium fluororubber O-rings, and heavy-duty Flange receptacles (SFBHFL2M to SFBHFL5F) molded with rugged marine-grade metal housings—such as 316L Stainless Steel, Titanium Alloy, or Naval Brass—for rugged pressure hull enclosure penetration.
• Specialized Infrastructure Fittings: Oilfield-hardened pressure-balanced assemblies (PBOF2M to PBOF5F) and protective dummy sealing plugs (DC2M to DC5F) to isolate and shield inactive electrical lines[cite: 1].

Key Technical Specifications & Core Features

• 100% Brand Interchangeability: Designed with standard international interface profiles that are fully compatible, mateable, and interchangeable with leading global subsea brands (such as SubConn and Seacon), drastically minimizing international spare parts inventory and maintenance friction[cite: 1].
• Wet-Mateable Capability: Engineered with tight-tolerance rubber sealing lips that allow seamless underwater connecting and disconnecting operations while fully submerged or in harsh marine splash-zones, ensuring immediate plug-and-play field reliability[cite: 1].
• Deep-Sea Performance Rating: Rated for standard operational hydrostatic pressures up to 60MPa, guaranteeing absolute zero-leakage performance at extreme diving depths reaching 6,000 meters[cite: 1].
• Optimized Electrical Parameters: Maintains a steady current rating of 10A per pin under an operational voltage of 550V AC/DC, backed by a superior insulation resistance rating of ≥200MΩ @ 1000V DC and low contact resistance (<0.01Ω)[cite: 1].
• Extreme Temperature Endurance: Certified to preserve structural material flexibility and sealing integrity across a harsh operating temperature envelope ranging from -60°C to +80°C[cite: 1].

Industrial Applications & Working Conditions

Сайт Standard 2-5 Pin Subsea Rubber Series is intentionally designed to perform under high-vibration, deep-water hydrostatic loads, intense salt spray, and severe ultraviolet aging conditions[cite: 1]. Key deployment fields include:

1. Marine Robotic Systems (ROVs & AUVs)

Acts as the primary umbilical connection interface for light-to-medium Remotely Operated Vehicles (ROVs) and Autonomous Underwater Vehicles (AUVs)[cite: 1]. These 2-to-5 pin configurations are critical for channeling telemetry commands, continuous diagnostic sensor data, and localized power lines from main pressure hulls to peripheral thruster modules, sensor arrays, and robotic arms[cite: 1].

2. Subsea Instrumentation & Monitoring Arrays

Deployed extensively across oceanographic observation networks, hydrophone arrays, seismic monitoring probes, seabed detection arrays, and environmental sensor packages[cite: 1]. The low contact resistance and high insulation parameters ensure stable low-voltage signal routing and continuous battery loopbacks with zero signal attenuation over long-term subsea deployment cycles[cite: 1].

3. Underwater Visual & Lighting Equipment

Serves as the mission-critical connection backbone for high-definition underwater network cameras, diving monitoring boxes, and high-power LED underwater searchlights[cite: 1]. It reliably handles high-inrush current demands and stable high-frequency video feedback transmission across volatile depth changes and intense ocean current displacements[cite: 1].

4. Offshore Energy & Hydrological Stations

Utilized across offshore wind farm sub-stations, marine tidal energy converters, offshore oil and gas drilling manifolds, and aquaculture infrastructure[cite: 1]. The heavy-duty neoprene molding resists biofouling, marine growth, and severe mechanical pulling forces common during heavy-sea deployment and recovery operations[cite: 1].
