Delphi Metri-Pack Housings: A Comprehensive Overview Delphi Metri-Pack housings are a widely recognized series of electrical connectors designed for automotive and industrial applications. These housings are part of the Metri-Pack connector system, known for its durability, reliability, and versatility in harsh environments. The Metri-Pack series includes multiple connector sizes, terminal options, and sealing configurations, making it suitable for a broad range of electrical connections. Key Features 1. Robust Design Metri-Pack housings are engineered to withstand extreme conditions, including high temperatures, vibration, and exposure to moisture, chemicals, and dust. The materials used, such as high-temperature thermoplastics, ensure long-term performance in demanding applications. 2. Multiple Configurations The housings are available in various cavity sizes (e.g., 150, 280, 480, 630, and 800 series) to accommodate different wire gauges and current ratings. This flexibility allows for customization based on specific electrical requirements. 3. Secure Terminal Retention The connectors feature a positive locking mechanism that ensures terminals remain securely seated, preventing accidental disconnection due to vibration or mechanical stress. Secondary locking options further enhance reliability. 4. Sealing Options Many Metri-Pack housings are available with integrated sealing grommets or overmolded seals, providing IP67 or higher protection against water and dust ingress. This makes them ideal for underhood, exterior, and other exposed applications. 5. Compatibility The housings are designed to work with Metri-Pack terminals, ensuring a reliable electrical connection. They support both crimped and stamped terminals, allowing for efficient assembly in manufacturing processes. Applications Metri-Pack housings are commonly used in: - Automotive wiring harnesses (engine control modules, sensors, lighting) - Industrial machinery and equipment - Agricultural and construction vehicles - Marine and off-road applications Advantages - High Reliability: Proven performance in extreme environments. - Ease of Assembly: Tooling and terminals are widely available, simplifying installation. - Modularity: Multiple housing sizes and terminal options enable scalable designs. Conclusion Delphi Metri-Pack housings provide a robust, flexible, and reliable solution for electrical connections in demanding environments. Their durability, sealing capabilities, and compatibility with various terminals make them a preferred choice across automotive and industrial sectors. Whether for high-vibration applications or exposure to harsh elements, Metri-Pack housings ensure secure and long-lasting electrical performance.
