The housing itself is a blue PA66 shell — glass-filled nylon 6/6 — rated for -30°C to 105°C, so it lives in engine compartments and outdoor cabinets without getting brittle. The 0.098" (2.50mm) pitch is the footprint spec that matters: it's a hair tighter than the older 2.54mm standard, meaning the matching header must be from the same GIC family, not a generic 0.100" header. What this housing is NOT is a complete connector. The listing shouts it in the note: Contacts Not Included. You order the crimp socket terminals separately — TE's part number for the female contact in this series. The housing is the shell; the terminals are the business end. If you're filling a BOM line for a 4-circuit harness, make sure the terminal line item is there too.
Mating and Locking — the Latch Does the Work
The Latch Lock fastening type means the housing has a molded ramp that clicks over the header's catch when fully seated. That audible snap is your confirmation the pair won't separate under cable strain or machine vibration. Free-hanging (in-line) mounting means it's designed to sit in the middle of a harness, not on a panel or board — the latch is the only retention. The crimp termination means you'll need the correct TE hand tool or automatic press for the socket contacts; no soldering, no IDC.
Sourcing and Lifecycle — Active, but Order the Full Set
The blue colour is the standard GIC identifier; no colour variants are listed. The bulk packaging means they ship loose in bags, not on tape-and-reel — fine for harness shops, less convenient for automated pick-and-place if you're panel-mounting the header side.
