NOTE
B. Mating Force
A maximum of 0.834 N [3 oz- -force] per contact is required for full mating of the modules.
C. Mating Sequence and Wipe Length
These connectors have three levels of sequencing during mating: first mate, last break (FMLB), reliable
mate, and fully mated. The relative distances between sequencing levels as a function of the distance
between the top of the backplane and the centerline of Row A of the daughtercard module is given in
Figure 13.
To ensure full mating of modules, the recommended minimum distance between the top of the backplane
and the centerline of Row A of the header (daughtercard module) and related dimensions are given in
Figure 13.
Wipe length is calculated by subtracting the reliable mating point dimension and the fully mated condition
dimension. Refer to Figure 13.
D. Durability
A total of 500 mating cycles are allowed for durability.
i
FMLB is the first and last instance in a mating cycle where the pin comes in contact with the beam, but has not
deflected the beam. Reliable mate is the first and last instance in a mating cycle where the pin has completely
deflected the beam and the beam is supplying full normal force to the pin. Refer to Figure 13.
