4-Position IDC Connector for 20 AWG Discrete Wires
The 1-2106003-4: The 4.00 mm cable pitch matches the board-side pitch, so the IDC slots align with the SMT pads on the footprint. The closed-end feature acts as a wire-stop, preventing over-insertion during assembly — a detail that saves rework when the harness is built against a fixed wire length.
SMT Right-Angle Mounting for Board-Edge Harnessing
The Tape & Reel packaging confirms this part is intended for automated pick-and-place lines — not a hand-solder repair part.
Wire Gauge Constraint — 20 AWG Only
The IDC slot geometry is sized for 20 AWG wire. The evidence does not list a wire range, so treat this as a single-gauge part.
