The 0.163" (4.14 mm) pitch and matching 0.163" (4.14 mm) row spacing give it a compact footprint for a 3-row, 15-circuit layout — the extra row packs more circuits into a shorter housing length compared to a 2-row design at the same pitch.
This housing ships empty. The housing accepts either gender, so you pick the terminal based on whether this half is the plug or the receptacle in your harness. Common mating terminals include the 170366 series for the female side and 170359 for the male side; confirm wire gauge compatibility with your chosen terminal before committing the BOM line.
The free-hanging (in-line) mounting type means this housing is intended for cable-to-cable or cable-to-panel connections, not PCB mounting.
