Ultra-Compact 2-6 Pin Watertight Connectors

Product Overview & Series Introduction

Сайт Ultra-Compact 2-6 Pin Watertight Connectors series by HYSF Subsea (Xiamen Chuida Technology Co., Ltd.) represents an independently developed, high-reliability product line specifically engineered for extremely space-constrained subsea applications. Featuring a minimal physical footprint and an exceptionally lightweight design, this micro-circular series satisfies the absolute strict application requirements for minimal cutout sizes on marine instrument mounting panels. As a nationally accredited high-tech enterprise driven by independent innovation, HYSF provides premium domestic substitution for imported core marine parts, successfully breaking the long-standing international brand monopoly in the high-end deep-sea connectivity sector.

Every connector system in this series is manufactured through an advanced unibody High-Temperature Vulcanization (HTV) molding process, integrally forming the premium gold-plated copper contacts and cable plug within a heavy-duty neoprene rubber body. Despite its miniature dimensions, this architecture delivers exceptional environmental sealing, reliable corrosion resistance, and robust electrical stability. To optimize space usage on specialized infrastructure panels and small pressure vessels, the series offers complete physical sets, including:

• Bulkhead Feedthrough Receptacles: Ultra-compact threaded receptacles (SFCXBH2M to SFCXBHEM) featuring an optimized 3/8-24UNF-2A installation profile and a base mounting radius of just 9.3 mm for ultra-dense clustering[cite: 1]. Receptacle shells are precision-machined from elite marine metals—such as 316L Stainless Steel, Titanium Alloy, or Naval Brass—paired with specialized O-rings to maintain absolute pressure integrity[cite: 1].
• Space-Saving Orientations: Specialized Ultra-Compact Right-Angle bulkhead receptacles (SFCXBHRA2M to SFCXBHRA6M) designed to minimize vertical protrusion and side profiles in tightly packed instrument clusters[cite: 1].
• Cable & Protection Components: Flexible Ultra-Compact Female cable assemblies (SFCXL2F to SFCXL6F) with customizable tail lengths[cite: 1], alongside matching protective dummy sealing plugs (SFCXDC2F to SFCXDC6F) paired with durable nuts to completely isolate uncoupled circuits from moisture and biofouling[cite: 1].

Key Technical Specifications & Core Features

• Dry-Environment Mating Architecture: Note that this ultra-compact series does not support wet-mating; connections must be completed and locked in a dry environment prior to underwater deployment to guarantee maximum initial sealing margins[cite: 1].
• Deep-Sea Pressure Rating: Engineered and rated for operational hydrostatic pressures up to 60MPa, providing zero-leakage security and absolute structural stability at diving depths down to 6,000 meters[cite: 1].
• Optimized Electrical Parameters: Safely supports low-voltage, low-current data and power distribution, maintaining a steady current rating of 5A per pin for 2 to 4-pin layouts and 2A per pin for 5 to 6-pin variants under a working voltage of 550V AC/DC[cite: 1]. Backed by an insulation resistance of ≥200MΩ @ 1000V DC and low contact resistance ($<0.01\Omega$)[cite: 1].
• Brutal Thermal Envelope: Certified to preserve material flexibility, physical lock integrity, and environmental sealing margins across extreme operating temperatures ranging from -60°C up to +80°C[cite: 1].

Industrial Applications & Working Conditions

Сайт Ultra-Compact 2-6 Pin Subsea Rubber Series is intentionally designed to perform as an ideal interconnect solution under high-vibration, deep-water hydrostatic loads, and intense salt spray working conditions[cite: 1]. Key deployment fields include:

1. Micro Sensor Networks & Probes

Serves as the primary high-integration connection interface for miniature underwater sensors, oceanographic observation networks, small environmental monitoring probes, and localized chemical detection packages[cite: 1]. The low contact resistance ensures pristine transmission of highly sensitive sensor signals[cite: 1].

2. Miniaturized Underwater Monitoring Equipment

Extensively deployed across portable diving monitoring systems, subsea data loggers, and localized testing instrumentation pools[cite: 1]. The ultra-compact layout maximizes available space for battery modules and computational chips while maintaining zero-leakage security[cite: 1].

3. Marine Visual & Secondary ROV Telemetry Breakouts

Acts as the ideal small-footprint signal transmission interface for micro underwater network cameras, optical lenses, or as secondary sensor breakout blocks on Remotely Operated Vehicles (ROVs) and Autonomous Underwater Vehicles (AUVs)[cite: 1]. It passes high-definition commands or visual feedback paths cleanly through a single minimal cutout opening[cite: 1].

4. High-Pressure Sealed Cabin Modules

Utilized to transmit low-voltage signals or localized electrical loops into subsea electronics pods, offshore wind farm sub-station junction boxes, and marine defense equipment[cite: 1]. The tough neoprene body resists mechanical impact, salt spray corrosion, and biological fouling during prolonged deployments[cite: 1].
