Breakaway Header, 8 Circuits, 30 µ" Gold
The 22-28-4087: This is a Molex KK 100 breakaway header assembly — 8 circuits, with 30 µ" gold plating on the contact area. The breakaway (BKWY) design means you can snap the pin strip to the exact position count your board needs, though this one ships as an 8-position fixed assembly. The 30 µ" gold over nickel on the mating face handles repeated connect-disconnect cycles without fretting corrosion, which matters if this header sees field service or test-point duty.
