3-640440-4 in TE IDC Connectors Family
The 3-640440-4 belongs to the MTA-100 series from TE Connectivity, a widely utilized family of Insulation Displacement Contact (IDC) connectors designed for mass termination of wires to printed circuit boards. These connectors feature a 0.100-inch (2.54mm) pitch and are engineered for 22 AWG discrete wires or notched ribbon cables. They provide a reliable, gas-tight connection suitable for low-to-medium power signals in industrial and consumer electronics where efficiency and repeatable assembly are critical requirements.
Variants in This Sub-Family
Variants within this IDC sub-family primarily differ in position count, ranging from 2 to 28 circuits, and contact plating options such as gold for high-reliability or corrosive environments. Additionally, while the 3-640440-4 is specific to 22 AWG (red housing), other variants are color-coded to support different wire gauges, such as 24 AWG (white) or 26 AWG (blue), ensuring proper contact force for each wire diameter.
