The 2042230006 is a 6-position, single-row plug housing from Molex's Squba 1.8 series, on a 1.80mm pitch.
The mating half is a Squba 1.8 receptacle housing (female, with locking ramp) that holds the female crimp terminals. The free-hanging (in-line) mounting type means it is used as a plug on a wire harness, not board-mounted.
