4-640440-0 in TE Connectivity Rectangular IDC Family
The 4-640440-0 is part of the MTA-100 series from TE Connectivity, a high-reliability family of mass termination assembly connectors. These rectangular IDC (Insulation Displacement Contact) receptacles are designed for 22 AWG wire-to-board connections. Utilizing a pre-loaded contact system, they enable efficient high-speed termination without stripping insulation. Engineers frequently use this family in industrial and commercial electronics where secure, vibration-resistant cable-to-header interfaces are required on a 0.100 inch (2.54mm) pitch.
Variants in This Sub-Family
Variants within this sub-family are primarily distinguished by wire gauge compatibility and circuit count. While the 4-640440-0 is optimized for 22 AWG wire (indicated by the red color-coding of the housing), other members support 24 AWG (white) through 28 AWG (green). Additionally, options include various plating finishes such as gold for high-cycle or low-level signal applications, and different housing configurations like closed-ends or feed-through types.
