The closed-end design blocks the back of the housing, so the IDC contacts bottom out at a consistent depth and the wire insertion stops at the right point every time. ## Contact Plating and Termination — 80 µ\" Tin on the IDC Joint The thickness matters because an IDC termination relies on the contact beam slicing through the wire insulation and cold-flowing the tin into the conductor strands. A thin flash would not fill the interstices reliably; 80 µ\" gives the gas-tight joint enough material to hold contact resistance stable through thermal cycling. The tin finish is the standard choice for the MTA-100 line — it matches the header pins for a tin-on-tin interface that works well in low-cycle, low-current signal and power applications inside a controlled environment. ## Mounting and Mating — Right-Angle Wire Exit, Free-Hanging This receptacle is free-hanging (in-line) with a right-angle wire exit — the cable exits 90° from the mating axis, which keeps the harness profile low against the board. The 22 AWG wire gauge is the only size the IDC slot accepts; do not try 20 or 24 AWG because the beam geometry and insulation displacement slot are tuned for the 22 AWG diameter. The 1-1703095-1 is a different connector (4-position, 5.00mm pitch, natural housing) and is not a functional substitute for this 3-circuit, 0.100\"-pitch MTA-100 receptacle.","metaTitle":"TE MTA-100 3-643498-3, 3-Pos IDC Receptacle, 0.100\" Pitch","metaDescription":"TE MTA-100 3-643498-3 3-position IDC receptacle, 0.100\" pitch, tin-plated contacts, locking ramp.
