MTA-100 IDC Receptacle, 4-Position, Gold Contacts
It uses a 0.100" (2.54 mm) pitch, matching the standard MTA-100 header footprint. This is a single-row, free-hanging (in-line) or right-angle mount connector, suited for internal wire-to-board harnesses in control panels, appliances, and industrial equipment where IDC assembly speed matters.
Termination and Wire Fit
This is an IDC (insulation displacement) connector — the 24 AWG wire is pressed into the contact slot, piercing the insulation without stripping or crimping. The closed-end feature means the back of the housing is sealed, preventing wire push-through. For field service, the gold-on-gold contact interface tolerates multiple reconnections better than a tin-plated IDC contact would.
No official second-source or successor is recorded on this line; the MTA-100 series is a mature TE portfolio, and this 4-position gold-contact variant is a standard catalog item.
