Ultra-Compact 12-28 Core Watertight Connectors

Product Overview & Series Introduction

Сайт Ultra-Compact 12-28 Core Watertight Connectors series by HYSF Subsea (Xiamen Chuida Technology Co., Ltd.) represents an independently developed, high-reliability product line engineered specifically for high-density multi-channel signal routing in extremely space-constrained subsea applications. Featuring a minimal physical footprint and an exceptionally lightweight micro-circular geometry, this high-integration series satisfies the absolute strict application requirements for minimal cutout sizes on marine instrument panels and pressure hulls. 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 and ultra-high contact density, this architecture delivers exceptional environmental sealing, reliable corrosion resistance, and robust electrical stability. To optimize space usage on specialized infrastructure panels, compact data housings, and small underwater vehicles, the series offers complete physical sets[cite: 1]:

• Bulkhead Feedthrough Receptacles: Ultra-compact threaded receptacles (SFCXDBH12M to SFCXDBH28M) designed 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].
• High-Flexibility Cable Solutions: Micro-diameter female cable assemblies (SFCXDIL12F to SFCXDIL28F) featuring high-flexibility polyurethane or neoprene outer sheaths engineered to withstand rugged deployment forces[cite: 1].
• Protection Components: Rigid matching protective dummy sealing plugs (SFCXDDC12F to SFCXDDC28F) paired with durable locking nuts to completely isolate uncoupled circuits from moisture, salt corrosion, and biological fouling[cite: 1].

Key Technical Specifications & Core Features

• Dry-Environment Mating Architecture: Note that this ultra-compact high-density series does not support wet-mating; connections must be fully completed and locked in a dry environment prior to underwater deployment to guarantee maximum initial sealing margins[cite: 1].
• Deep-Sea Pressure Rating: Rated for operational hydrostatic pressures up to 60MPa, providing zero-leakage security and absolute structural stability at simulated diving depths down to 6,000 meters[cite: 1].
• High-Density Electrical Parameters: Safely supports low-voltage, low-current data and power distribution, maintaining a steady current rating of 5A per pin for 12-pin models, a split current profile for denser core arrays (e.g., 8 pins @ 5A + 4 pins @ 2A for 16-pin variants), and up to 2A/5A limits across ultra-dense layouts up to 28 pins 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 12-28 Core 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 & Oceanographic Probes

Serves as the primary high-integration connection interface for miniature underwater multi-sensor clusters, seabed observation networks, oceanographic scientific research instruments, and localized environmental monitoring probes[cite: 1]. The low contact resistance ensures pristine transmission of highly sensitive sensor signals without data attenuation[cite: 1].

2. Miniaturized Underwater Monitoring Equipment

Extensively deployed across portable diving monitoring systems, subsea data loggers, testing instrumentation pools, and high-pressure sealed chambers[cite: 1]. The ultra-compact layout maximizes available internal space for battery modules and computational chips while maintaining zero-leakage security under continuous high pressure[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]. The massive pin density (up to 28 cores) allows multiple parallel camera feeds, command signals, and low-power lines to pass cleanly through a single minimal cutout opening[cite: 1].

4. Advanced Sonar Platforms & Hydrophone Arrays

Utilized to transmit multi-channel acoustic detection telemetry, subsea seismic monitoring arrays, and naval defense hardware[cite: 1]. The heavy-duty neoprene rubber body resists mechanical impact, intense vibration, salt spray corrosion, and biological fouling during prolonged marine deployments[cite: 1].
