640467-1 is a socket header connector designed for the 5.0 mm Power Key Connectors (5.0 PKC) wire-to-board connector system. This component features a 5-circuit configuration with a standard tail dimension of 1.300 inches (33.02 mm) and is rated UL94V-2 for flammability. The connector uses pre-tin socket finish and is compatible with Universal MATE-N-LOK plug housings, providing reliable mating with pin contacts. The 5.0 mm contact centerline spacing and compact 19.4 mm mated height design make it suitable for power circuit applications in home appliances, particularly gas appliances. The connector incorporates protective design features including locking levers surrounded by walls to prevent tangling with wires and housing lances that further protect wired contacts during assembly and potting processes.
