Panel lock and latch lock keep the mate tight
The PNIRR-02V: The panel lock feature holds the housing in the panel cutout before the header is mated, simplifying assembly on a harness line. Once mated, the latch lock gives an audible click — a half-turn loose is a dropout, but this latch won't back off.
ROHS3 compliant.
The closest functional second-source within the PNI series is the PNIRR-03V, a 3-position version of the same panel-mount receptacle housing with identical 2.00mm pitch, latch lock, and PA66 material.
