3-position, 6.20 mm pitch — the wide-pitch Grace Inertia housing that ships empty
Its 6.20 mm pitch is the widest in the immediate GIC family — noticeably broader than the 5.08 mm pitch of the 1-2069882-6 sibling or the 2.50 mm pitch of the 1-1376477-6 plug. That extra spacing gives you more creepage for moderate-voltage runs and makes the housing easier to handle in a gloved hand on a harness board. The housing uses a friction lock for mating retention — no secondary latch, just the interference fit between the receptacle and the header shroud. You should hear it seat; if it backs out, it's scrap.
Contacts not included — the most common sourcing miss on this line
The buyer must order the matching crimp tab terminal separately. This is the single most frequent mistake on this part: the BOM line shows the housing but the terminal gets forgotten until the harness build starts. The housing accepts tab-type contacts (male pin terminals) terminated via standard crimp tooling. The natural colour (unpigmented PA66) is the default for this series; no colour-coding is provided on this variant, so visual keying relies on the housing shape and the friction lock orientation.
The base product number is 1746978, with the -1 suffix indicating the 3-position variant in natural PA66.
