Round Compact 2-8 Core Watertight Connectors

Product Overview & Series Introduction

Les Round Compact 2-8 Core Watertight Connectors series by HYSF Subsea (Xiamen Chuida Technology Co., Ltd.) represents an independently developed, high-performance product line engineered for space-constrained underwater applications. Designed to balance structural compactness with absolute electrical reliability, this series delivers smaller footprints and lighter weights compared to standard subsea connectors, offering excellent cost-effectiveness and seamless integration capabilities. As a nationally accredited high-tech enterprise driven by independent innovation, HYSF provides premium domestic substitution for imported core marine products, successfully breaking the long-standing international brand monopoly.

Every connector configuration in this series features an ultra-compact, precision-engineered unibody structure where the cable and gold-plated copper contacts are integrally formed through a High-Temperature Vulcanization (HTV) process into heavy-duty neoprene rubber bodies. This structural composition ensures high sealing performance and exceptional durability. To accommodate strict panel cutout limits and minimal space constraints inside marine enclosures, the series is available in complete physical system sets, including:

• Cable Solutions: Ultra-flexible Round Compact Male/Female inline cable assemblies (SFYXIL2M to SFYXIL8F) with customizable tail lengths to match specific engineering wiring sequences[cite: 1].
• Bulkhead Feedthrough Receptacles: Precision threaded receptacles (SFYXBH2M to SFYXBH8F) featuring a compact 3/8-24UNF-2A installation profile and a base mounting radius of just 9.3 mm[cite: 1]. Receptacle shells are machined from elite marine metals—including 316L Stainless Steel, Titanium Alloy, or Naval Brass—paired with premium fluororubber O-rings to maintain hermetic pressure integrity under deep-water loads[cite: 1].
• Protection Components: Rigid matching dummy sealing plugs (SFYXDC2M to SFYXDC8F) paired with durable POM or stainless steel locking nuts to completely isolate and seal uncoupled channels from moisture, corrosion, and biological fouling[cite: 1].

Key Technical Specifications & Core Features

• Advanced Space Optimization: Specially engineered for space-sensitive configurations, requiring a minimal installation radius that allows maximum component density on subsea pressure hulls and junction boxes[cite: 1].
• Underwater Wet-Mateable Capability: Adopts precision wet-mate technology with tight-tolerance rubber sealing lips that wipe away moisture during coupling, allowing safe connecting and disconnecting operations while fully submerged[cite: 1].
• Deep-Sea Pressure Rating: Rated for operational hydrostatic pressures up to 60MPa, ensuring absolute zero-leakage performance and structural stability at diving depths reaching 6,000 meters[cite: 1].
• Electrical Parameters: Supports steady current routing of 5A per pin for 2 to 4-pin configurations and 2A per pin for 5 to 8-pin dense arrays under a working voltage of 550V AC/DC[cite: 1]. Features low contact resistance ($<0.01\Omega$) and high insulation resistance ($\ge 200\text{M}\Omega$ @ 1000V DC)[cite: 1].
• Extreme Thermal Range: Certified to preserve material flexibility, structural locking compliance, and environmental sealing margins across a brutal operating envelope from -60°C to +80°C[cite: 1].

Industrial Applications & Working Conditions

Les Round Compact 2-8 Core Subsea Rubber Series is intentionally designed to perform under high-vibration, deep-water hydrostatic loads, high-salinity corrosive salt sprays, and harsh underwater environments[cite: 1]. Key application deployment sectors include:

1. Micro Remotely Operated Vehicles (ROVs & AUVs)

Acts as the primary space-saving power and telemetry command interface for portable, small-sized underwater robotic systems, Autonomous Underwater Vehicles (AUVs), and micro-submersibles[cite: 1]. The lightweight, compact form factor prevents balance disruption on miniature frames while securely channeling critical control loops from internal pressure hulls to external thruster modules and small robotic joints[cite: 1].

2. Miniaturized Sensor Probes & Scientific Instruments

Extensively deployed across oceanographic scientific research infrastructure, seabed observation networks, hydrophones, seismic detection packages, and specialized environmental monitoring probes[cite: 1]. The consolidated 2-to-8 pin round geometry permits clean routing of low-voltage computational data and battery power channels back to central data loggers with zero signal attenuation[cite: 1].

3. Compact Underwater Cameras & Visual visual Lighting Systems

Serves as the mission-critical interconnect backbone for high-definition underwater network cameras, portable diving monitoring boxes, and specialized LED searchlights[cite: 1]. The micro-circular layout efficiently handles steady power loops alongside digital signal feedback paths through a single minimal enclosure opening[cite: 1].

4. Subsea Junction Boxes & Enclosures

Utilized across high-pressure sealed housings, offshore wind farm monitoring arrays, marine aquaculture hardware, and underwater search and rescue gear[cite: 1]. The unibody vulcanized construction resists biofouling and marine growth, successfully enduring severe mechanical shock and pulling forces common during deployment and recovery operations[cite: 1].
