Micro 2-8 Pin Watertight Connectors

Product Overview & Series Introduction

Les Micro 2-8 Pin Watertight Connectors series by HYSF Subsea (Xiamen Chuida Technology Co., Ltd.) is a high-performance, micro-circular interconnect solution specifically engineered to reduce physical size and overall system weight. Developed as part of our deep-sea rubber product line, this series offers premium domestic substitution for imported core products, successfully breaking international brand monopolies in high-end marine connectivity.

Every configuration features an optimized, compact layout with gold-plated copper contacts integrally molded into high-temperature vulcanized neoprene rubber bodies. This design provides exceptional environmental sealing and electrical reliability while maintaining a minimal structural footprint. To support space-constrained installations on small hulls, portable probes, and compact enclosures, the series offers multiple physical form factors:

• Cable Solutions: Ultra-flexible Micro Male/Female inline cables (MCIL2M to MCIL8F) and space-saving, low-profile right-angled L-shaped variants (MCILRA2M to MCILRA8F)[cite: 1].
• Bulkhead Feedthroughs: Compact threaded receptacles (MCBH2M to MCBH8F) with tight-tolerance 7/16-20UNF-2A installation dimensions, alongside heavy-duty Flange receptacles (SFMCBHFL2M to SFMCBHFL8F)[cite: 1]. Receptacle shells are precision-machined from top-tier marine metals, including 316L Stainless Steel, Titanium Alloy, or Naval Brass[cite: 1].
• System Accessories: Hardened micro oilfield-style layouts (MCPBOF2M to MCPBOF8F) and protective dummy sealing plugs (MCDC2M to MCDC8F) to guarantee sealing integrity on uncoupled channels[cite: 1].

Key Technical Specifications & Core Features

• Full Global Brand Compatibility: Precision-engineered with standard international interface dimensions, providing 100% direct mating interchangeability with leading international subsea brands (such as SubConn and Seacon) to significantly lower replacement costs and minimize cross-brand maintenance friction[cite: 1].
• Submerged Wet-Plug Capability: Equipped with premium neoprene sealing lips that wipe away moisture during the connection cycle, enabling safe, secure underwater mating and unmating operations while fully submerged or exposed in splash zones[cite: 1].
• Deep-Sea Pressure Rating: Rated for operational hydrostatic pressures up to 60MPa, providing zero-leakage security at diving depths down to 6,000 meters[cite: 1].
• Electrical Reliability: Maintains a steady current rating of 10A per pin for 2 to 4-pin configurations and 5A per pin for high-density 5 to 8-pin variants[cite: 1]. Operating voltage is rated up to 550V AC/DC, backed by an insulation resistance threshold of ≥200MΩ @ 1000V DC and low contact resistance (<0.01Ω)[cite: 1].
• Extreme Temperature Flexibility: Engineered to ensure structural sealing and material compliance across a harsh operating thermal envelope from -60°C to +80°C[cite: 1].

Industrial Applications & Working Conditions

Les Micro 2-8 Pin Subsea Rubber Series is intentionally designed to optimize spacing efficiency under high-vibration, deep-water hydrostatic loads, intense salt spray corrosion, and severe ultraviolet (UV) aging conditions[cite: 1]. Key application deployment sectors include:

1. Portable Marine Robotic Systems (ROVs & AUVs)

Acts as the ideal compact data and power interface for small-sized Remotely Operated Vehicles (ROVs), Autonomous Underwater Vehicles (AUVs), and micro-submersibles[cite: 1]. The lightweight properties ensure that light robotic frames maintain precise buoyancy management while routing core telemetry control loops[cite: 1].

2. Miniaturized Sensor Probes & Monitoring Packages

Extensively deployed to connect space-sensitive oceanographic observation instruments, hydrophones, seismic monitoring arrays, and environmental monitoring probes[cite: 1]. The low contact resistance ensures pristine, unattenuated signal transmission for sensitive low-voltage computational data[cite: 1].

3. Underwater Network Cameras & Vision Systems

Serves as the mission-critical interconnect backbone for high-definition underwater cameras, integrated light-and-camera modules, and low-light vision boxes[cite: 1]. The 2 to 8-pin density efficiently handles power input loops alongside digital signal feedback paths through a single minimal cutout opening[cite: 1].

4. Offshore Energy & Deep-Water Subsea Enclosures

Utilized across subsea junction boxes, offshore wind farm monitoring nodes, and hydraulic power manifolds[cite: 1]. The unibody molded neoprene housing resists marine biofouling growth and withstands intense pulling forces, keeping critical electronics dry under extreme deep-water working conditions[cite: 1].
