Key Features of the HUADA SDC-51S Micro Rectangular Electrical Connector

Temperature Range: Maximum Operating Temperature: +125 °C This high maximum temperature ensures that the connector can function effectively in environments with elevated temperatures, such as industrial machinery or aerospace applications.
Minimum Operating Temperature: -55 °C The low minimum temperature rating allows the connector to be used in extremely cold conditions, making it suitable for use in polar regions or high-altitude applications.
Insulation Resistance: 5000 mΩ: High insulation resistance is crucial for preventing electrical leakage, ensuring that the connector maintains its integrity and performance even in high-voltage applications. This feature is particularly important in sensitive electronic equipment where even minor leakage can cause significant issues.
Work Pressure: 4.4 KPa: The ability to operate under low-pressure conditions makes this connector ideal for use in environments such as high-altitude aircraft or space applications, where atmospheric pressure is significantly lower than at sea level.
Impact Resistance: 490 m/s²: High impact resistance ensures that the connector can withstand sudden shocks and mechanical impacts without damage. This is essential for applications in military vehicles, aerospace, and other environments where mechanical shocks are common.
Vibration Resistance: 10-2000Hz 196m/s²: The connector’s ability to resist vibrations across a wide frequency range ensures stable performance in environments with continuous or intermittent vibrations, such as automotive, aerospace, and industrial machinery.
Relative Humidity: 40℃, 98%: The connector can operate effectively in high humidity conditions, making it suitable for use in tropical climates or marine environments where moisture levels are high. This feature helps prevent corrosion and ensures long-term reliability.
Contact Resistance: 15 mΩ: Low contact resistance is essential for efficient electrical conductivity, reducing power loss and heat generation. This ensures that the connector can handle high currents without significant voltage drops, making it suitable for power distribution applications.
Current Capacity: 1.8A: The connector’s ability to handle a current of up to 1.8A makes it suitable for a variety of low-power applications, including electronic devices, communication equipment, and control systems.
Mechanical Life: 300 cycles: The connector is designed for a long mechanical life, capable of enduring up to 300 mating and unmating cycles without significant wear or degradation. This makes it ideal for applications where connectors are frequently connected and disconnected.
Pressure Resistance: 300 V: The connector can withstand a voltage of up to 300V, ensuring safety and reliability in electrical systems. This feature is particularly important in applications where connectors are exposed to high voltages, such as power supplies and industrial equipment.
Number of Cores: Available in configurations with 5, 9, 15, 21, 25, 31, 37, 51, 66, and 74 cores.
This wide range of core configurations allows the connector to be used in a variety of applications, from simple signal transmission to complex data and power distribution systems.
Design and Structure
Miniaturized Design: The connector’s compact dimensions make it ideal for applications where space is limited, such as in portable electronic devices, medical equipment, and compact control systems.
Crimping Cross Section: 0.035mm² to 0.06mm² wire This range ensures secure and reliable connections, suitable for various wire sizes. The crimping design provides a strong mechanical and electrical connection, reducing the risk of disconnection or signal loss.
