Automotive-Steckverbinder

Under-hood applications expose connectors to temperatures exceeding 150°C, requiring materials with high thermal resistance and low expansion coefficient. Our connectors utilize polyphenylene sulfide (PPS), liquid crystal polymers (LCP), and high-temperature-rated PBT compounds, ensuring stability across wide thermal gradients. Metal-plated polymer housings enhance heat dissipation, preventing thermal degradation of internal components. Contact interfaces employ beryllium copper (BeCu) and phosphor bronze alloys with gold or silver plating to prevent oxidation at elevated temperatures. Thermal expansion differentials are mitigated through precision-molded interfaces that maintain consistent engagement force, reducing the risk of open circuits due to material deformation. 

Automotive connectors must resist water, dust, oil, and aggressive chemicals, particularly in chassis, powertrain, and underbody applications. Our solutions incorporate multi-layer sealing architectures with fluoro silicone elastomers to provide IP67 and IP69K-rated ingress protection. Hydrophobic coatings on connector surfaces repel moisture and contaminants, preventing premature corrosion. Terminal plating technologies, including electroless nickel-phosphorus and immersion tin, offer enhanced resistance to galvanic corrosion in high-humidity environments. Overmolded strain reliefs ensure that cable-to-connector transitions remain mechanically robust, preventing water ingress through capillary action.
