The closed-end design blocks the last cavity, preventing partial insertion and ensuring the wire stops at the correct depth. Termination is IDC — the 22 AWG wire is pressed into the slot using a manual or pneumatic hand tool; the insulation is displaced by the contact tines, making gas-tight connection without solder. The receptacle mounts free-hanging (in-line) or at a right angle to the wire axis, depending on the harness routing. ## Contact Finish and Duty Tin-lead is a legacy plating — it provides good corrosion resistance and solderability but has a lower mating-cycle life compared to gold. For applications requiring frequent disconnect/reconnect cycles, a gold-plated variant of the MTA-100 series would be a better fit.","metaTitle":"TE MTA-100 643813-4, 4-Pos IDC Receptacle, 0.100\" Pitch","metaDescription":"TE MTA-100 643813-4 4-position IDC receptacle, 0.100\" pitch, tin-lead contacts, locking ramp.
