4-Position Discrete-Wire IDC Connector for 22 AWG
The 2-2106431-4: It uses a 0.157" (4.00 mm) board-side pitch, which is wider than the 0.050" or 0.100" pitches common on ribbon IDC headers — this spacing gives each wire its own lane on the board and in the cable, making it a fit for point-to-point harnesses where you want to route each conductor separately rather than as a flat ribbon. The housing is natural (unpigmented) and carries a feed-through feature, meaning the IDC slot passes through the body so the wire can be inserted straight through — useful when you need to daisy-chain or continue the wire beyond the connector.
Pitch and Footprint — What 0.157" Means for Layout
At 0.157" (4.00 mm) pitch, this connector occupies more board real estate per circuit than a typical 0.100" ribbon IDC header, but the trade-off is that 22 AWG wire fits comfortably in the IDC slot without crowding. For a 4-position part, the total footprint is about 0.630" wide — compact enough for most control or sensor interface boards.
Termination and Assembly — IDC on Individual Wires
No stripping, no crimping — just a one-step press. The feed-through design means the wire can pass straight through the connector body, which simplifies daisy-chaining to a second connector or continuing the run to a termination point. The surface-mount right-angle orientation means the connector is reflow-soldered to the board first, then the wires are inserted after soldering — plan the assembly sequence accordingly.
