- Housing and durability: The connector body is made from impact-resistant polycarbonate for reliable use in demanding conditions. - Contact quality: The contacts are solid copper with nickel plating, and the connectors are silver plated to provide low resistance and a stable, high-conductivity connection. - Weather and vibration performance: The plug is designed for dependable weather resistance and vibration damping. It cannot be cross-connected and is typically used to transfer auxiliary power from the vehicle to the trailer. - Electrical performance: The silver plating helps minimize resistance for efficient power transfer and a stable connection under load. - Compatibility and use: Suitable for standard vehicle-to-trailer auxiliary power connections. Not intended for cross-connecting. Use scenarios: - Towing a trailer or caravan to supply trailer lighting, battery charging, and other auxiliary systems from the towing vehicle. - RV or camper setups where auxiliary power from the vehicle is needed for trailer appliances during travel. - Off-road or exposed environments where weather exposure and vibration require a robust, reliable power connection between vehicle and trailer.
