WS Series EMI-Resistant Connector for Military Reconnaissance UAVs

MS27497 Military Connectors Series Specifications

Selecting an EMI-Resistant Connector for Military Reconnaissance UAV Communication Modules

For communication modules in military reconnaissance UAVs, electromagnetic interference (EMI) can disrupt critical data links. The connector choice directly impacts signal integrity and mission reliability. The WS series aviation connector, in its anti-interference configuration, is designed to address these challenges.

Key Selection Criteria for UAV Communication Connectors

When evaluating connectors for this application, focus on these core decision points:

• Shielding Effectiveness: The connector must provide robust protection against EMI to maintain signal integrity.
• Environmental Tolerance: It must withstand high-altitude radiation and temperature variations.
• Mechanical and Weight Constraints: The connector should be lightweight to preserve UAV endurance and durable enough for vibration.
• Signal Frequency Support: It must reliably transmit the required communication frequencies without degradation.

WS Series Anti-Interference Connector Specifications

The WS series anti-interference version is engineered for this specific military application. Its verified performance parameters include:

• Shielding Effectiveness: ≥ 90dB, compliant with the MIL-STD-461F standard for electromagnetic compatibility.
• Radiation Resistance: Up to 100krad, suitable for high-altitude, high-radiation environments.
• Weight: Less than 45g, minimizing impact on UAV payload and endurance.
• Frequency Range: Supports stable transmission of ultra-short wave communication signals (30~300MHz).

Application Fit and Installation Notes

This connector is suitable for the communication module of military reconnaissance UAVs where EMI resistance is a primary requirement. The shielding effectiveness ensures stable signal transmission even in contested electromagnetic environments. The radiation resistance is a critical factor for high-altitude operations. When integrating this connector, verify the mating interface and pin configuration against your specific module design to ensure compatibility. The lightweight construction helps maintain the UAV's operational range.

Selection Boundaries and Verification

While the WS series is a strong candidate, it is important to confirm that the specific model's pin count, keying, and mounting style match your module's requirements. The performance values listed are rated specifications; always verify them against your system's derating factors and testing conditions. For other UAV applications, such as flight control or sensor systems, different connector series may be more appropriate based on their specific electrical and environmental demands.
