What this Economy Power header fits
The 1-1318300-6 is a 6-position, single-row header from TE's Economy Power series, built for board-to-cable/wire connections at a 0.156" (3.96mm) pitch. That pitch is wider than typical signal headers — it's a deliberate spacing for power distribution, letting each contact carry 7.5A at 250VAC without crowding the board. The shrouded 1-wall design and friction lock keep the mating housing aligned and latched under vibration — common in industrial and lighting applications where a loose connector means a service call.
