This is a 6-pin 1.5mm pitch connector which mates directly with the connector on the Sharp GP2Y1010AU0F optical dust sensor. This is a ZH series JST connector. You will need six matching crimp pins in conjunction with this part, they can be found here.
We also carry a mating, PCB mounting, connector for this housing.
