Key Features of the HUADA SDC-9SW1 Micro Rectangular Electrical Connector

Contact Spacing: This is the distance between individual contacts within the connector. A smaller contact spacing allows for more pins in a compact footprint, making it ideal for high-density applications. The SDC-9SW1, likely having a contact spacing of 0.75mm, is well-suited for applications where space is limited.
Crimping Cross Section: This indicates the size of wire that can be used with the connector. A smaller cross-section can handle lower currents, while a larger cross-section can accommodate thicker wires for higher currents.
General & Detailed Specifications: These typically refer to industry standards or specifications that the connector meets. The SDC-9SW1 likely conforms to GJB7245-2011 and Q/MB25122-2018, ensuring quality, reliability, and compatibility with other components.
Operating Temperatures: This indicates the temperature range within which the connector can safely operate. The SDC-9SW1, with a maximum operating temperature of +125°C and a minimum of -55°C, is likely suitable for a wide range of environments.
Insulation Resistance: This measures the electrical resistance between the contacts and the connector housing. A high insulation resistance of 5000 mΩ in the SDC-9SW1 ensures proper isolation and prevents leakage currents.
Work Pressure: This refers to the amount of pressure the connector can withstand. The SDC-9SW1 can likely withstand 4.4 KPa of pressure, making it suitable for applications with potential pressure fluctuations.
Impact Resistance: This indicates the connector's ability to withstand shocks and vibrations. The SDC-9SW1, with an impact resistance of 490m/s2, is likely suitable for applications in environments with high vibration levels (automotive, aerospace).
Vibration Resistance: This indicates the connector's ability to handle sustained vibrations. The SDC-9SW1 is likely capable of withstanding vibrations in the range of 10-2000Hz 196m/S2, making it suitable for applications with constant vibration.
Relative Humidity: This specifies the humidity level at which the connector can operate reliably. The SDC-9SW1 is likely capable of operating in environments with relative humidity of 40℃, 98%, making it suitable for a wide range of applications.
Contact Resistance: This measures the electrical resistance between mating contacts. The SDC-9SW1 likely has a contact resistance of 15 mΩ, indicating good electrical conductivity and reduced power loss.
Current Rating: This indicates the maximum current the connector can safely handle. The SDC-9SW1 has a current rating of 1.8A, determining its power capacity.
Mechanical Life: This measures the number of mating and unmating cycles the connector can endure before failure. The SDC-9SW1 likely has a mechanical life of 300 cycles, indicating its durability.
Pressure Resistance: This indicates the maximum voltage the connector can withstand safely. The SDC-9SW1 can likely handle a pressure resistance of 300V.
