To determine the centroid of the connector, use the four corners of the connector edges marked
with red circles as shown in the following gure. By using a high-accuracy opcal measurement
instrument, measure the distance D. Distance D should be 66.612 mm (nominal). The allowable
distance D and tolerance is 66.612 ±0.04 mm center to center. The following table shows the
recommended opcal measurement instrument specicaons.
