Now that we have some guided information on Interface cleanliness, let’s continue with Interface Gauging.
Did you Know…
Incorrect center pin depths can produce inaccurate measurements and in the case of protruding center pins can damage test devices, adapters, and test ports. Frequent interface gauging can detect gauging problems before they ruin mating devices.(See Table I for Connector Interface Pin Depths)
