The AMPMODU System 50
connector family includes a
wide variety of high density
board-to-board (thru-hole
and surface-mount) and
cable-to-board connectors.
AMPMODU System 50 is
composed of one- and two-
row receptacles and post
headers on .050 x .100
[1.27 x 2.54] spacing
between contacts for
extreme density and
efficient use of printed
circuit board area.
AMPMODU System 50
receptacles and header
assemblies can be
categorized in three groups:
board-mount headers,
board-mount receptacles
and cable-to-board
receptacles. Receptacle
contacts and mating .015
[0.38] square posts are
formed from high
conductivity copper alloy
and are selectively plated
with gold to promote higher
performance and reliability.

AMPMODU Interconnection System
AMPMODU System 50 Connectors
Board-mounted thru-hole
post headers and
receptacle connectors are
available for right-angle
and vertical mating
configurations. Surface-
mounted connectors are
available in vertical, double
row styles for parallel
stacking applications.
Shrouded post headers
provide polarization to
mating cable receptacles
and aid alignment of mating
connectors. Unshrouded
headers allow close
stacking of daughter cards.
Vertical stacking connectors
space parallel mated
boards as shown in the
illustration on page 63.
Housings on all board-
mount assemblies are made
of high temperature tolerant
materials and incorporate
stand-offs for free drainage
of flux cleaning solutions.
Cable-to-board connectors
have integral latches for
positive locking to shrouded

mating headers (thru-hole or
surface-mount). Ribbon
cable connectors mass
terminate 30 AWG [0.05
mm
[0.03 mm
[0.64] centerline ribbon
cable with PVC or Teflon
insulation.
Connectors for mass
termination to FFC cable or
flexible etched circuitry
have dual beam contacts;
options include shielded
cable and solder tabs. Both
types of cable connectors
are available as component
parts and as completed
assemblies.
The variety of components
and application possibilities,
combined with small size
and outstanding quality,
make AMPMODU
System 50 suitable for high
density systems.
