Fixed Board Male
Connectors
Type A, B, C, M, M-MSC and M-MSC-
rev. fixed board male connectors have
signal contact positions identified by
row letters and column numbers, shown
right, viewed toward the frontside of the
backplane.
Contact positions can be filled or left
unfilled, as required, for a customer's
circuit arrangement. Contact pins for
each position can be specified from any
of the options shown below, excepting:
Use the codes A-V to specify front/rear
contact for each position on the special
option chart, page 67.
Midplane Cross-connect
Applications
Cross-connections, require the
feedthrough posts to be rotated 90°, so
that the mating surface aligns with the
female receptacle spring beams.

Rows z and f, for ground return
shield contacts only, must always be
level 3.
Row b is not available for level 3
(length 11.2 [.441])contacts when
mating with a right angle female con-
nector.
For rear board cable connectors, use
posts providing rear mating length 1
after allowing for board thickness,
unless sequenced mating is required.
Consult the chart page 66.
