Rated for -30°C to 105°C, it handles the thermal range you'd expect inside an automotive junction box or an industrial control cabinet. The blue PA66 housing is keyed by colour in the series, which helps avoid a mis-mate on the line when multiple cavity counts are running side by side.
Contacts Not Included — What That Means for Your BOM
Factor that second line item into your procurement list; the housing alone won't complete a mated pair.
Where It Sits in the Grace Inertia Family
This 2-position blue housing is the entry point in the single-row Grace Inertia plug range. The sibling 2-1971793-3 is a red 2-position, and 2-1971793-4 is a yellow 2-position — same pitch, same latch lock, same PA66 material, same free-hanging crimp termination. The colour difference is the only functional delta; it's a line-side visual key for harness assembly when multiple 2-position circuits run in the same bundle. The 2-1747066-2 is also a blue 2-position plug but uses glass-filled PA66 instead of straight nylon — check your application's temperature or chemical exposure requirements if you're considering that swap.
No official second-source cross-reference exists beyond the TE Grace Inertia series itself.
