High-Density Connectivity Solutions for Next-Gen ROVs & AUVs
Engineered for compact spaces and extreme depths. HYSF provides intermateable, pressure-rated connectors that power the future of underwater robotics.
Industry Challenges
Overcoming Space Constraints
Modern ROVs and AUVs are becoming increasingly compact. Integrating more sensors into smaller electronics pods requires high-density interconnects without increasing the bulkhead footprint.
Ensuring Uninterrupted Signal Integrity
High-definition 4K video feeds and advanced sonar data demand zero-interference transmission. Our connectors prevent signal degradation even in high-vibration and deep-sea environments.
Reliability at Extreme Depths
A single connector failure can jeopardize a mission or lead to the loss of expensive autonomous vehicles. Reliability isn't just a feature; it's the lifeline of your subsea operation.
Featured Solutions
Ultra-Compact Round Small Series (2-6 Pins)
When even the Miniature series is too large for your application, the HYSF Round Small Series provides the ultimate solution. Specifically engineered for Micro-ROVs, handheld dive gear, and compact subsea sensors, this series offers an ultra-micro footprint and significantly reduced weight. Despite its size, it maintains the same robust sealing and pressure integrity required for professional subsea missions, ensuring that your lightweight platforms remain agile and efficient.
- Featherweight Design: Optimized for weight-sensitive AUVs and portable underwater devices.
- Micro-Footprint: The smallest form factor in our catalog, ideal for extremely confined bulkhead spaces.
- Simplified 2-6 pin configurations for rapid sensor and power connectivity.
Miniature High-Density Series (2-25 Cores)
Our Miniature series has become the trusted industry standard for global ROV and AUV manufacturers. Engineered for high-performance integration, it offers up to 25 pins within a remarkably compact housing. This allows engineers to manage complex power and data streams through a single penetration, significantly reducing the weight and complexity of your subsea bulkheads.
- Maximize Space: High-density pin configurations.
- Depth Rated: Verified performance up to 7,000m.
- Customizable: Available in 316L SS, Titanium, or Aluminum.
L-Shaped (90°) Space-Saving Solutions
Designed specifically for tight-fitting sensor enclosures and compact ROV frames, our L-shaped (90-degree) connectors solve the most common cable management challenges. By orienting the cable parallel to the bulkhead, these connectors minimize mechanical stress and prevent cable fatigue, enabling a more streamlined and hydrodynamic ROV design.
- Stress Reduction: Prevents cable bending and fatigue.
- Ultra-Low Profile: Fits where standard straight connectors can't.
- Full Range: Available from 2 to 16-core configurations.
Precision Connectivity for Subsea Robotics
Reliability is the lifeline of any ROV or AUV mission. HYSF delivers high-performance interconnect solutions engineered to meet the unique demands of autonomous underwater systems—combining space-saving designs with battle-tested durability at extreme depths.
100% Intermateable with ROV Standards
Eliminate compatibility risks. Our connectors are fully intermateable with existing industry-standard interfaces used by major ROV manufacturers. Whether for field repairs or new builds, HYSF offers a seamless, plug-and-play alternative that maintains system integrity without the "brand-name" lead times.
Operational Excellence at 7,000m
Deep-ocean exploration leaves no room for error. Each HYSF connector is rigorously hydrostatically tested to ensure stable signal and power transmission at pressures up to 7,000 meters. This makes them the ideal choice for Work-Class ROVs and deep-sea AUVs operating in high-pressure abyssal zones.
Advanced Materials for Agility & Strength
Optimize your vehicle's payload and buoyancy. We offer a selection of high-grade materials, including 316L Stainless Steel for durability and Titanium for high-strength, lightweight requirements. Tailor your connectivity to meet specific weight-to-performance ratios for more agile and efficient subsea robotic platforms.
ROV Connectivity & Technical Support FAQ
Find answers to the most common technical questions regarding HYSF underwater connectors for ROV and AUV applications. Our engineering team is dedicated to ensuring your subsea robotics maintain peak performance in the most challenging environments.
Are HYSF connectors fully intermateable with existing ROV industry standards?
Yes. Our Miniature and Standard series are designed to be 100% intermateable with industry-standard interfaces (including SubConn® and others). This “Form, Fit, and Function” compatibility allows ROV manufacturers and service providers to use HYSF as a direct, high-reliability replacement or upgrade without any mechanical modifications to their existing bulkheads or cable assemblies.
What is the maximum depth rating for your ROV connectors?
Most of our ROV-specific connectors, including the Miniature 2-25 core series, are hydrostatically pressure-tested for operations at depths up to 7,000 meters (approx. 10,000 PSI). This makes them suitable for everything from shallow-water observation ROVs to deep-ocean Work-Class ROVs and scientific AUVs.
Do you offer L-shaped (90-degree) connectors for tight-fitting ROV sensor pods?
Absolutely. We specialize in L-shaped (right-angle) connectors for both our Miniature and Standard ranges. These are specifically engineered for compact ROV designs where internal space is limited, helping to reduce cable strain and allowing for a more streamlined and hydrodynamic vehicle profile.
Can HYSF provide customized cable assemblies for AUV tethers?
Yes, we provide full-service custom cable assemblies. We can tailor the cable length, shielding, and jacket material (such as PUR or Neoprene) to meet your specific AUV tethering or ROV internal wiring requirements. Every assembly is 100% tested for electrical continuity and insulation resistance before shipping.
How do HYSF connectors handle corrosion in long-term subsea deployments?
To ensure longevity in harsh saline environments, our connector housings are available in 316L Stainless Steel and Titanium (Grade 5). We use high-resilience Neoprene rubber for the overmolding and gold-plated brass contacts to ensure optimal conductivity and prevent oxidation during long-term offshore deployments.
What is the typical lead time for HYSF ROV connectors?
We understand that subsea projects often operate on tight schedules. While many industry providers require 8–12 weeks, HYSF typically maintains a lead time of 3 to 5 weeks for standard configurations. For urgent ROV maintenance or rapid prototyping needs, we also keep a selection of common core counts in stock for immediate dispatch.
Can I request samples for pressure testing or compatibility checks?
Yes, we support engineering evaluations. We offer sample units for qualified ROV/AUV projects so that your technical team can verify the intermateability, material quality, and pressure integrity of our connectors firsthand. Please contact our sales gallery with your project specifications to discuss sample availability and shipping arrangements.
