The 3-2106751-4: This connector terminates 24 AWG wire via IDC — no stripping required, but the wire diameter must match the slot geometry. The single-row, 4-position layout accepts all positions loaded. The feed-through feature allows wires to enter from one side and exit the other, which simplifies daisy-chain or pass-through wiring in a harness.
The 4-position, single-row layout fits within the board edge.
