Anti-Spark Gold-Plated UAV Connector 90A with Precharge Resistor
Product Summary
The DXT90H-M (reinforced male) and DXT90S-F (anti-spark female) are a matched UAV connector set designed for high-current power connections in agricultural drones, multi-rotor UAVs, and LiPo battery systems. The female connector features a built-in high-power precharge resistor and two-stage contact design to effectively eliminate electric arcs during battery plugging, preventing terminal burnout. With a continuous current rating of 90A (10AWG wire, temperature rise ≤85°C) and a peak transient current of 120A, these connectors ensure reliable power delivery in demanding flight conditions.
Key Features
- Anti-spark design: Built-in precharge resistor in DXT90S-F female connector suppresses arcing during LiPo battery connection, protecting terminals from burnout.
- Reinforced terminals: Thickened gold-plated banana plugs (4.5mm) on DXT90H-M provide stable contact under continuous drone vibration, preventing power loss from loose connections.
- High current capacity: Handles 90A continuous and 120A peak current, suitable for high-drain UAV applications.
- Robust construction: PA66 high-temperature nylon housing with UL94 V-0 flame retardancy, operating from -20°C to +120°C.
- Durable plating: Gold-plated terminals (0.3µm standard, thicker optional) resist corrosion, passing 48h salt spray testing.
- Secure locking: Tight locking structure prevents loosening in multi-rotor and agricultural drone environments.
