WY Series 31-Pin Aviation Waterproof Connector – High-Density, Industrial & Aerospace Reliability
The WY Series 31-Pin Aviation Waterproof Connector is a high-density circular connector engineered for industrial automation, aerospace, and defense applications that demand reliable, durable, and waterproof connectivity. With a large 31-pin capacity, it is perfect for complex signal, data, and power networks in space-limited installations, providing secure multi-circuit connections in critical systems.
Unlike standard aviation connectors, this
model emphasizes waterproof performance, mechanical robustness, and
factory-backed manufacturing excellence, making it suitable for
mission-critical equipment and harsh industrial environments.
Built for Extreme Environments
The WY 31-Pin Connector is designed to withstand:
Dust, moisture, and water exposure with IP67/IP68-rated sealing
High vibration and mechanical shock, ensuring consistent electrical performance
Temperature fluctuations, maintaining conductivity in harsh environments
Heavy-duty operational cycles, perfect for 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 Features
