The TE Connectivity 3-644043-6 is a 6-position MTA-100 IDC receptacle, built for terminating discrete or ribbon cable in harness assemblies. It sits in the MTA-100 series at the standard 0.100" (2.54mm) pitch, which matches common header strips for board-to-wire signal runs. Gold plating at 30.0µin (0.76µm) on the female socket contacts handles repeated mating cycles without fret corrosion, suited for field-service or mildly corrosive environments.
Termination is IDC — the 26 AWG wire is pressed into the slot, displacing insulation to make contact.
