Automotive Weatherproof Connectors

Our factory specializes in precision mold manufacturing and injection molding. This automotive weatherproof connector is designed for outdoor vehicles such as commercial trucks and construction machinery. These applications face harsh conditions, including sun, rain, and dust.

We use custom precision molds and manufacture the housing from weather-resistant PA66 reinforced with glass fiber. It operates reliably within a temperature range of -40°C to 120°C. Whether in cold winters or hot engine bays, it maintains stable performance. This reliability is built on years of experience serving automotive clients.

Water and dust can damage electrical systems. To prevent this, we design a one-piece, double-layer rubber sealing structure combined with a secure latch lock. This dual protection achieves an IP67 rating.

This means the automotive weatherproof connector can withstand immersion in up to 1 meter of water for 30 minutes without water ingress. We perform air-tightness tests on every batch to ensure consistent sealing performance and long-term reliability.

We manufacture pin holes with high precision, maintaining a tolerance within ±0.02 mm. This ensures smooth insertion and a secure connection, resulting in stable signal and current transmission.

We also support custom orders. Simply provide your port size and required IP rating, and we will develop a dedicated mold tailored to your needs. Many clients inquire about protection levels-we reliably deliver IP67 performance for demanding environments.
