The TE Connectivity 3-647000-8 is an 8-position IDC plug from the MTA-100 series, terminated to 22 AWG discrete or ribbon cable via insulation displacement. Tin-plated male pins with 80.0µin (2.03µm) of contact finish suit moderate-cycle applications — think appliance wiring harnesses, industrial control panels, or internal power distribution where repeated mate-unmate cycles are infrequent.
The wire gauge is fixed at 22 AWG; using a different gauge risks an unreliable connection because the insulation diameter and conductor cross-section must match the slot geometry.
