Key Features of the HUADA SDC-66SN Micro Rectangular Electrical Connector

Contact Spacing: 0.75mm is likely the distance between individual contacts. This determines the density of contacts within the connector. Smaller spacing allows for more pins in a smaller footprint, making the connector suitable for high-density applications.
Crimping Cross Section: 0.035mm²~0.06mm² wire indicates the size of wire that can be used with this connector. This impacts the current carrying capacity.
General Specifications & Detailed Specifications: GJB7245-2011 and Q/MB25122-2018 are likely standards or specifications that the connector meets. These certifications ensure quality, reliability, and compatibility with other components.
Maximum & Minimum Operating Temperatures: +125 °C and -55 °C indicate the temperature range in which the connector can safely operate. This is crucial for applications exposed to various environments.
Insulation Resistance: 5000 mΩ indicates the resistance between the contacts and the connector housing. High insulation resistance ensures proper isolation and prevents unwanted current leakage.
Work Pressure: 4.4 KPa shows the amount of pressure the connector can withstand. This is relevant for applications where there might be pressure fluctuations or sealing requirements.
Impact Resistance: 490m/s² indicates the connector's ability to withstand shocks and vibrations. This is essential for applications in environments with high vibration levels, such as automotive or aerospace.
Vibration Resistance: 10-2000Hz 196m/S2 indicates the frequency range and amplitude of vibration the connector can withstand. This again is important for applications in vibrating environments.
Relative Humidity: 40℃, 98% indicates the humidity level at which the connector can operate. This is critical for applications in humid or wet environments.
Contact Resistance: 15 mΩ indicates the resistance between the mating contacts. Lower contact resistance ensures good electrical conductivity and minimal power loss.
Current Rating: 1.8A A indicates the maximum current the connector can safely handle. This is crucial for determining the power capacity of the connector.
Mechanical Life: 300 Cycles indicates the number of times the connector can be mated and unmated before failure. This is a measure of the connector's durability.
Pressure Resistance: 300 V indicates the voltage rating of the connector. This is important for determining the maximum voltage the connector can handle safely.
