If you notice any difference in the contact finishes of the M20-9730245 Connector Header from Harwin Inc., as shown in the image below,
please review the manufacturer’s response on this:
The parts are correct and in good condition, and their appearance can vary slightly from batch to batch.
“There’s no industry standard for gold flash. We believe it’s generally considered anything less than 10 µ”, but our flash plating is significantly thinner—probably closer to 0.5–1 µ”. That’s why it doesn’t have a deep gold color.
We don’t specify an exact plating thickness, only that it meets our performance specifications.”
