2-173983-2: TE CT Amp-In 2-Pin IDC Connector for 26-28 AWG
It uses a 0.079" (2.00mm) cable pitch and an identical 0.079" (2.00mm) board-side pitch, so the wire spacing matches the PCB footprint.
What bolts in — fit and termination
No stripping, no crimping — just the right tool for 26-28 AWG solid or stranded wire. The 2.00mm pitch means the PCB footprint has two through-holes on 2.00mm centers, and the right-angle pins solder into the board from the component side. Tin contact finish is standard for this connector class. It's fine for a fixed harness that mates a handful of times over its life.
