Backplane Usage 

„

The maximum allowable blind-mate tolerance is ± 1.50 mm in the X-axis.

„

The maximum allowable blind-mate tolerance is ± 1.00 mm in the Z-axis.

„

The above tolerances are based on the X-Y plane being perpendicular to Y-Z plane.

See Figure 6-2 and Figure 6-3 for the industry-standard connector pin dimensions and references.
