The 3-644083-4: It terminates 22 AWG discrete or ribbon cable using an IDC (insulation displacement contact) method, meaning the wire is pushed into a slot that pierces the insulation — no stripping or crimping needed.
This receptacle is built for 22 AWG wire only — the IDC slot dimensions are fixed at the factory for that gauge. Using a different wire size will either fail to cut insulation or damage the contact.
Typical mates are the TE 640441 series vertical headers or 640442 series right-angle headers.
Yes, the IDC contacts are designed specifically for 22 AWG discrete or ribbon cable. Using other wire gauges will not produce a reliable termination.
