NOTES:

1. Overall finish: Measure gold thickness in zone A or B, as applicable.

2. Localized finish: Apply gold to the inside and outside diameter of the contact in area X or Y. Measure gold

thickness on outside diameter of the contact at point B or C, as applicable.

3. On socket contacts with integral pressure members, area X (zone of tangency) extends from the tip of the

contact to .020 inch beyond the point of tangency, (point C) on the inside and outside diameter of the contact.

4. Dimensions are in inches.

5. Metric equivalents are given for information only.
