The single-wall shroud and friction lock keep the mating half aligned and latched under vibration. ## Pitch, position count, and why 8 loaded matters The 3.96mm pitch is a standard for wire-to-board power distribution — wide enough to route traces between pads on a single-layer board without necking down. The 9-position housing carries 8 loaded contacts; position 9 is a keying or polarization slot, not a missing circuit. Verify your BOM calls for 8 active circuits, not 9.","metaTitle":"1744109-4 TE Economy Power Header, 9 Pos, 3.96mm","metaDescription":"1744109-4 TE Economy Power 9-position (8 loaded) shrouded header, 3.96mm pitch, 7.5A, 250VAC, friction lock, tin contacts, UL94 V-0.
