Plug Housing for a 3-Wire Run
It uses a 2.00mm pitch and a single row of female socket cavities, so it matches a 3-circuit harness where you need a compact, keyed interconnect.
Ordering the Right Crimp Terminals
The mating half is a Grace Inertia 2.0 header (through-hole or SMT, depending on your board) with 3 pins on the same 2.00mm pitch. There is no secondary keying — the 3-position count and the latch orientation prevent mis-mating with different-position housings. If you need a wire-to-wire splice, a matching 3-position receptacle housing with crimp terminals does the job.
