28-Pin Male Grey Wire Harness Connector – Technical Description A 28-pin male grey wire harness connector is a standardized electrical component designed for secure and reliable interconnection in various electronic and electrical systems. This type of connector is widely used in automotive, industrial, consumer electronics, and telecommunications applications due to its durability, ease of installation, and consistent performance. Physical Characteristics The connector features a male interface with 28 pins arranged in a specific configuration, typically in a single or dual-row layout. The housing is constructed from high-quality grey thermoplastic material, providing excellent resistance to heat, chemicals, and mechanical stress. The grey color helps in quick identification and differentiation from other connectors in complex wiring systems. The pins are usually made of copper alloy with a tin or gold plating to ensure low contact resistance and corrosion resistance. The male pins are designed to mate precisely with corresponding female sockets, ensuring a stable electrical connection. The connector may include locking mechanisms such as latches or clips to prevent accidental disconnection in high-vibration environments. Electrical and Mechanical Specifications - Current Rating: Typically rated for 2A to 5A per pin, depending on wire gauge and material. - Voltage Rating: Suitable for up to 250V, making it ideal for low-voltage and signal applications. - Wire Gauge Compatibility: Supports AWG 22 to 28 wires, ensuring flexibility in different wiring setups. - Operating Temperature Range: -40°C to +105°C, allowing use in harsh environments. - IP Rating: Some variants may offer IP67 protection against dust and water ingress. Applications This connector is commonly used in: - Automotive wiring harnesses (ECUs, sensors, lighting systems). - Industrial control panels (PLC connections, motor controls). - Consumer electronics (appliances, audio systems). - Telecommunications equipment (routers, switches). Advantages - Secure Connection: Locking features prevent loosening under vibration. - High Durability: Resistant to wear, heat, and chemicals. - Easy Installation: Tool-less or crimp-style assembly options. - Space-Efficient: Compact design saves panel space. Conclusion The 28-pin male grey wire harness connector is a versatile and robust solution for electrical interconnections, offering reliability, ease of use, and adaptability across multiple industries. Its standardized design ensures compatibility with various female counterparts, making it a preferred choice for engineers and technicians.
