13-circuit Micro-Latch receptacle — what you're working with
The Molex 0510651300 is a 13-position receptacle from the Micro-Latch 51065 series, built on a 2.00mm pitch in a single-row layout.
That means you're buying just the 13-way housing shell — the female crimp terminals that go inside it are a separate line item.
Friction lock and mating compatibility
It's not a full secondary latch — think of it as a detent that resists casual pull-off from cable snag or light vibration. For the mating half, you're looking at the Micro-Latch 51065 series pin headers (vertical or right-angle, through-hole or SMT). The 13-position count is less common than 10 or 16 in this series, so double-check that the header side exists in 13 circuits before designing it in.
