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.","metaTitle":"TE 1746978-1 Grace Inertia 3-Pos Receptacle Housing, 6.20mm","metaDescription":"TE Connectivity 1746978-1 Grace Inertia 3-position receptacle housing, 6.20mm pitch, natural PA66, friction lock, crimp termination.
