Typical applications include power supply sense lines, low-current signal taps, and test-point headers on control boards.
The mating contact finish is 15 µinch (0.38 µm) gold over phosphor bronze — a mid-grade plating that supports roughly 100–200 mating cycles in clean environments. The post finish is gold flash only, which means the solder tail has minimal corrosion protection after soldering; the joint relies on the solder fillet for environmental seal. For applications requiring frequent disconnect/reconnect (field-service or test fixtures), consider a header with thicker gold plating (30 µinch or more) from the same AMPMODU Mod II family. The 87224-2 is best suited for one-time or occasional mating.
