Powering Mission-Critical UAVs with Reliable 60A Connectivity

High-current cable-to-board power connectors engineered for defense, security and demanding UAV battery systems.

Modern UAV platforms are required to carry more than just cameras. In defense and security applications, they may support surveillance, threat detection, ground asset tracking, disaster management, search and rescue, and crowd control.

As payload systems become more advanced, battery power connection becomes a critical part of the UAV design. Cameras, sensors and high-current payload electronics depend on stable power delivery throughout the mission — from take-off to landing.

In this application, the UAV required a reliable battery-to-board power connection capable of supporting continuous 60A current to a high-current payload. Harwin Kona was selected to provide the high-reliability connection needed for this demanding UAV power system.

Key Features

• High-current cable-to-board power connection
• Supports 60A current-carrying capacity
• 2-contact female cable connector mated to male PCB connector
• Suitable for demanding UAV battery power systems
• Supports secure cable termination with solder cups
• Help enable easier battery to disconnect and replacement
• Designed for high-reliability applications where power continuity is critical

 

Application and Market

Harwin Kona is suitable for UAV platforms and mission-critical electronic systems where compact, reliableand high-current power connectivity is required:

For UAVs operating in demanding environments, connector reliability directly supports mission uptime, payload stability and field serviceability.

 

Engineering Background

In a UAV power system, the battery-to-board connection must deliver current consistently while withstanding the demands of airborne operation. Movement, vibration, environmental changes and repeated battery handling can all place stress on the connector system.

The case study application involved a UAV platform operating up to 4,500 meters with temperature and humidity certification. The system required continuous 60A current from the battery to a high-current payload through a cable-to-board connection. The cable connector also required solder cups to support secure cable termination.

For engineers, this means the connector must do more than simply complete the circuit. It must provide a stable power path, reduce the risk of intermittent power loss and support reliable operation in a compact UAV design.

Harwin Solution

Harwin Kona provides the required high-current connection for this UAV battery power application.

The solution uses a Kona 2-contact female cable connector mated to a male PCB connector, delivering the high-reliability connection and 60A current-carrying capacity required by the payload system.

The PCB connector is positioned on the battery side, allowing the battery to be disconnected and replaced more easily when required. This supports practical serviceability, faster battery access and dependable power delivery during mission-critical operations.
