Split-Type Series Watertight Connectors

Product Overview & Series Introduction

The Split-Type Series Watertight Connectors product line by HYSF Subsea (Xiamen Chuida Technology Co., Ltd.) adopts an innovative split structure design engineered to realize centralized connection and quick assembly or disassembly of multi-channel signals and power supplies. This advanced engineering design allows one main receptacle to connect to multiple independent plugs simultaneously, which greatly reduces the number of required equipment hull openings and significantly lowers the cumulative risk of structural leakage. Every individual channel within the assembly features its own independent sealing mechanism, ensuring zero mutual interference between data or power lines.

Functioning effectively like a miniature sealed cabin, this series greatly improves system integration, optimizes space allocation, and enhances maintenance efficiency, making it the ideal choice for high-density underwater connections. Each assembly is manufactured through a unibody High-Temperature Vulcanization process where gold-plated copper contact pins are integrally molded within heavy-duty neoprene rubber bodies to guarantee long-term performance under deep-sea conditions[cite: 1]. The series supports complete custom modularity and is available across various multi-split structural formats, including:

• High-Density Channel Configurations: Precision-engineered options ranging from 8-Pin/4-Split up to ultra-dense 48-Pin/6-Split variations to accommodate highly complex subsea cable architectures[cite: 1].
• Centralized Feedthrough Receptacles: Threaded bulkhead receptacles (SF-XX-XAW-BH Series) machined with standard international interfaces to allow clean penetration into subsea instruments[cite: 1].
• Robust Cable Plugs & Protection Fittings: Independent inline male cables (SF-XX-XAW-IL Series) paired with matching protective split-type plug caps (SF-XX-XAW-DC Series) to isolate and shield any uncoupled signal paths[cite: 1].

Key Technical Specifications & Core Features

• Innovative Multi-Split Routing: Drastically reduces multi-device cabling complexity by consolidating independent signal lines from separate sensor clusters into a single centralized feedthrough receptacle[cite: 1].
• Deep-Sea Hydrostatic Sealing: Rated for operational hydrostatic working pressures up to 60MPa, providing zero-leakage security at extreme diving depths reaching 6,000 meters[cite: 1].
• Optimized Electrical Parameters: Safely maintains a steady current rating of 10A per pin for large-core profiles and 5A per pin for high-density layouts under an operational voltage of 550V AC/DC[cite: 1]. Backed by low contact resistance of less than 0.01Ω and a superior insulation resistance rating of greater than or equal to 200MΩ @ 1000V DC[cite: 1].
• Rigid Panel Mount Infrastructure: Designed for robust installation requiring a base mounting radius of 32.5 mm, an Ra1.6 surface finish, and a heavy-duty 1-14UNS-2A mounting thread with a thread length of 25 mm[cite: 1].
• Material Versatility: The unibody neoprene rubber molding works seamlessly with locking caps manufactured from standard POM or optional marine-grade 316L stainless steel to counter environmental deformation[cite: 1].

Industrial Applications & Working Conditions

The Split-Type Series Watertight Connectors line is purposefully engineered to operate under intense localized vibrations, deep-water hydrostatic loads, and complex wiring constraints across critical marine sectors[cite: 1]. Key deployment applications include:

1. Multi-Sensor Integrated Platforms

Acts as the centralized electrical backbone for underwater monitoring nodes that combine multiple independent sensors such as temperature, salinity, and flow probes on a single frame[cite: 1]. By funneling separate data loops into one split receptacle, it minimizes hull cutouts and simplifies sensor replacement cycles[cite: 1].

2. Underwater Control Systems

Serves as the primary power and command breakout interface for subsea distribution hubs and localized electronic control pods[cite: 1]. The independent sealing of each channel prevents cross-talk and ensures that a localized fault in one terminal node will not compromise adjacent electrical circuits[cite: 1].

3. Seabed Detection Arrays & Oceanographic Networks

Extensively deployed across marine scientific research networks, hydrophone setups, and seismic monitoring arrays on the ocean floor[cite: 1]. It handles mixed power inputs and data loops cleanly over long-term deployment cycles without experiencing signal attenuation or insulation degradation[cite: 1].

4. Advanced ROV Telemetry Breakouts

Utilized to route centralized control branches on Remotely Operated Vehicles (ROVs) and Autonomous Underwater Vehicles (AUVs)[cite: 1]. Its compact cabin-like structure facilitates fast assembly and teardown in shipboard deck laboratories, maximizing field serviceability[cite: 1].
