Hirose Electric DF63 Series 3.96mm Pitch Board-to-Wire Connectors are rated for up to 10 Amps max. when using 16 AWG wire MAX 10A/pin AWG 16 7A AWG 18. The DF63 locking mechanism delivers a clear and tactile click that prevents incomplete mating and incorrect insertion. The pin header is equipped with a guide post to prevent reverse insertion on the PCB. The lance is actually part of the housing instead of being a part of the terminal. This prevents tangled wires during assembly. The wall structure between the contacts helps to isolate the contacts and prevents short circuits between contacts. The DF63 series is capable of being potted, up to 5mm. Glass-reinforced resin is used on the pin header to prevent solder cracks due to thermal contraction. Keying options prevent incorrect connections due to the use of multiple connectors on the same board. When using identical pin counts, two versions are available with different keying options.
