Board-to-Wire Header at 0.100" Pitch — 3 Circuits, Friction Lock
The 640456-3: The shrouded-1 wall design provides basic polarization to prevent mis-mating, and the friction lock holds the mating connector in place under moderate vibration — a practical choice for point-to-point wiring in control panels and general-purpose equipment.
The friction lock engages with the mating housing latch to prevent accidental disconnection.
Choose the 640456-3 when you need the wider pitch for routing density or higher voltage, and the 1-292164-1 when you need more circuits in a tighter pitch.
