AMPMODU Interconnection System
Board-to-Board Right-Angle Headers
AMPMODU 50/50 Grid
Right-Angle Headers will
accommodate a variety of
high density packaging
applications; right-angle
board-to-board applications
when mated with vertical
receptacles (page 15) and
right-angle cable-to-board
applications when mated
with cable connectors
(page 21). The small
.050 x .050 [1.27 x 1.27]
centerline contact spacing
allows efficient use of the
PC board area.
Mechanical support of the
headers to the PC board is
provided by non-protrusive
metallic holddowns
designed for .062 [1.57] or
thicker PC boards. These
holddowns are of the same

design as those used in the
vertical headers (page 16)
and receptacles (page 15).
There are also metallic tabs
that are soldered to the sur-
faces of the PC board pads
for added support.
AMPMODU 50/50 Grid
Right-Angle Headers are
available in double-row, in
either latching or non-
latching versions, and in
sizes ranging from 10
through 100 positions (in 10
position increments). The
latching version provides
positive retention when
mated with the latching
cable connector (page 21).
All headers feature polariza-
tion to help prevent mis-
alignment during mating.
