Technical Information: Cable Materials
Flat ribbon cables employed in
cable assemblies are of industry-
standard geometry - AWG 26 or
AWG 28 conductor size, 0,050
inch (1,27 mm) center-to-center
conductor spacing, and PVC
insulation material. This geometry
is specifically designed to meet
the stringent, high-speed, digital
signal transmission requirements
of the computer and peripheral
equipment industries.
The close-tolerance spacing of the
parallel-conductor geometry
produces the consistently uniform
and predictable controlled
impedance and capacitance
characteristics shown in the table
below. The use of PVC insulation
uniformly convoluted as measured
in a ground-signal-ground
configuration.
Cable assemblies also are
compatible with industry-standard
IDC-mass-termination techniques
and maintain excellent impedance
continuity at the cable/contact
juncture. Their symmetrical
convolutions permit reliable
termination from either side to
accomodate both „stripe-up“ and
„stripe-down“ cable configurations.
„Tear-down“ separation between
conductors is readily
accomplished for circuit routing of
separate conductors.
Cables also have excellent flexing
characteristics and are easily
folded to any required
configurations.
Solid conductors in the 0,050-inch-
flat-ribbon cable geometry also are
available on special order. Send
specifications for samples and
