The 20-pin brown male automotive connector, part number 33482-2103, is a specialized electrical component designed for use in automotive applications. This connector is engineered to provide a secure and reliable connection between wiring harnesses and electronic modules, sensors, or other critical vehicle systems. Its robust construction ensures durability in harsh automotive environments, including exposure to vibrations, temperature fluctuations, moisture, and chemicals. Key Features and Specifications 1. Pin Configuration and Design - The connector features 20 male pins arranged in a specific layout to ensure proper mating with its corresponding female counterpart. The brown housing provides visual identification and may indicate its application or voltage rating within the vehicle’s electrical system. - The pins are typically made of high-conductivity materials such as copper alloy, often plated with tin or gold to enhance corrosion resistance and ensure optimal electrical conductivity. 2. Housing Material and Durability - The connector housing is constructed from high-quality thermoplastic materials, such as PA66 (nylon), which offers excellent resistance to heat, chemicals, and mechanical stress. The brown color may serve as a coding mechanism to differentiate it from other connectors in the system. - Sealing grommets or rubber seals may be integrated into the design to provide IP-rated protection against dust, water, and other contaminants, making it suitable for under-hood or exterior automotive applications. 3. Termination and Locking Mechanism - The connector utilizes crimp, solder, or IDC (insulation displacement contact) termination methods for secure wire attachment. A positive locking mechanism, such as a latch or secondary lock, ensures that the connector remains firmly mated even under vibration or mechanical stress. - Some versions may include CPA (connector position assurance) features to prevent accidental disconnection. 4. Electrical Performance - Rated for low-voltage automotive systems (typically 12V or 24V), the connector supports signal and power transmission with minimal voltage drop. - Current and voltage ratings vary depending on wire gauge and pin design, but it is generally suited for moderate power and data applications. Applications This 20-pin male connector is commonly used in: - Engine control units (ECUs) - Transmission systems - Body control modules (BCMs) - Lighting systems - Infotainment and dashboard electronics Advantages - Reliability: Engineered for long-term performance in demanding conditions. - Ease of Installation: Designed for quick and secure mating with compatible female connectors. - Standardization: Follows industry-standard dimensions and electrical ratings for compatibility with various automotive systems. In summary, the 20-pin brown male automotive connector (33482-2103) is a critical component in modern vehicle electrical systems, offering durability, secure connections, and resistance to environmental factors. Its design ensures efficient power and signal transmission while meeting the rigorous demands of automotive applications.
