Key Features of the HUADA SDC-51SL3 Micro Rectangular Electrical Connector

Core Features:
Number of Pins (Cores): 51 - This is a significant pin count for a micro connector, indicating its ability to handle complex applications requiring many signal or power lines. It's ideal for devices with dense circuitry, needing to pack a lot of functionality into a small space.
Pitch: 0.635 mm - This refers to the very small spacing between contact points. A smaller pitch allows for a higher density of pins within a compact footprint, making it perfect for space-constrained devices where every millimeter counts.
Contact Spacing: 0.75 mm - The spacing between individual contact points. A tighter spacing allows for a greater number of pins within a given area.
Performance and Reliability Features:
Operating Temperature Range: -55°C to +125°C - This wide range indicates the connector can operate reliably in both very cold and hot environments, increasing its versatility across diverse applications. It can handle the extremes of temperature that many electronic devices might face.
Insulation Resistance: 5000 mΩ - A high insulation resistance is critical for good electrical isolation between the connector's contacts. It helps minimize leakage current and prevent short circuits, ensuring a reliable connection.
Contact Resistance: 15 mΩ - Low contact resistance is essential for signal integrity and power efficiency. A lower value indicates a strong connection with minimal resistance, promoting efficient signal transmission and preventing signal degradation.
Current Rating: 1.8 A - This indicates the maximum current the connector can safely handle without overheating or damage. It determines the power capacity of the connection, relevant for different applications.
Mechanical Life: 300 - The number of mating cycles (connection and disconnection) the connector can withstand before experiencing significant wear. A higher mechanical life indicates durability and longevity, meaning it can be used repeatedly without degrading.
Pressure Resistance: 300 V - This feature highlights the connector's ability to withstand a certain voltage without failure, crucial for safety and reliability in electrical systems. It ensures the connector can handle typical operating voltages without compromising performance.
Environmental Resilience Features:
Impact Resistance: 490 m/s² - This indicates the connector can withstand shock and impact forces, making it suitable for applications in harsh environments or with potential for vibrations. It can handle sudden shocks or bumps that might occur in transportation or use.
Vibration Resistance: 10-2000 Hz, 196 m/S² - This demonstrates the connector's ability to operate reliably under vibrations. This feature is important for applications in automotive, aerospace, and industrial environments where vibrations are common.
Relative Humidity Resistance: 40°C, 98% - This signifies the connector's ability to maintain its performance in high humidity conditions, ensuring consistent functionality in humid environments. It can operate reliably in environments with high moisture levels.
