The TE Connectivity MTA-100 4-644312-3 is a 13-position IDC receptacle built for discrete or ribbon cable termination. It sits in the MTA-100 family at the standard 0.100" (2.54mm) pitch, which mates directly with the matching MTA-100 pin headers. The closed-end design blocks wire push-through on the last cavity — a detail that matters when you're terminating a ribbon and don't want a stray strand poking out the far side.
Termination and wire gauge
This is a one-step IDC termination for 24 AWG wire — the insulation is displaced as the cover is pressed down, no stripping required.
Locking ramp and retention
In a panel or harness that sees vibration — say, inside an industrial cabinet near a motor drive — that ramp keeps the pair from walking apart.
