WY Series 31-Pin Aviation Waterproof Connector Overview

The WY Series 31-Pin Aviation Waterproof Connector is a high-density circular connector designed for industrial automation, aerospace, and defense applications that require reliable, durable, and waterproof connectivity. With a 31-pin capacity, it supports complex signal, data, and power networks in space-limited installations, providing secure multi-circuit connections in critical systems.

WY Series 31-Pin Aviation Waterproof Connector

This model emphasizes waterproof performance, mechanical robustness, and factory-backed manufacturing quality, making it suitable for mission-critical equipment and harsh industrial environments.

Built for Harsh Operating Conditions

The WY 31-Pin Connector is engineered to withstand demanding environmental and mechanical conditions:

WY Series 31-Pin Connector Design

  • Dust, moisture, and water exposure with IP67/IP68-rated sealing
  • High vibration and mechanical shock for consistent electrical performance
  • Temperature fluctuations that affect conductivity in harsh environments
  • Heavy-duty operational cycles common in aerospace, defense, and industrial machinery

Its high pin count allows engineers to consolidate multiple lines into a single robust connector, saving space and simplifying maintenance.

Key Selection Considerations

When evaluating this connector for your application, consider the following decision points:

WY Series Connector Manufacturing

  • Pin Density: The 31-pin configuration suits multi-signal, data, and power transmission, reducing the need for multiple connectors.
  • Environmental Protection: IP67/IP68-rated sealing prevents ingress from water, dust, or corrosive environments.
  • Mechanical Durability: The reinforced metal housing resists vibration, impact, and repeated mating cycles.
  • Contact Performance: Precision contacts ensure low resistance and stable signal transmission for long-term reliability.
  • Space Efficiency: High pin density in a circular form factor allows efficient panel and device integration.

Manufacturing and Quality Assurance

The WY Series 31-Pin Connector is produced with professional manufacturing capabilities that support its reliability:

WY Series Connector Production

  • R&D Expertise: Over 15 years of experience in aviation and industrial connector design, with patented technologies for waterproof and high-density connectors.
  • Precision Manufacturing: CNC machining, injection molding, and metal stamping ensure tight tolerances and consistent performance.
  • Quality Control: Environmental, electrical, and mechanical testing (salt spray, vibration, mating cycles) validates durability and field readiness.
  • Vertical Integration: In-house tooling, assembly, and cable integration streamline production and maintain high quality.
  • Customization Capabilities: Flexible pin layouts, cable lengths, shielding options, and OEM branding tailored to customer requirements.

Typical Applications

  • Aerospace avionics and instrumentation
  • Defense and military control systems
  • Industrial automation and robotics
  • Complex sensor networks and monitoring systems
  • Control panels requiring multi-signal connections
  • Harsh environment outdoor machinery

Application Boundaries

This connector is best suited for applications requiring high-density signal or power routing in demanding environments. It is not intended for low-pin-count, cost-sensitive consumer applications, nor for installations where the mating side cannot accommodate a 31-pin circular interface. Confirm your cable outside diameter, conductor size, and electrical load before specifying the connector to ensure proper fit and performance.
