Cannon have responded to meet these
requirements - the result is TEMPUS
CBC 20, a two part modular plug and
receptacle connector system. TEMPUS
CBC 20 is suitable for a variety of
equipment ranging from laptops to
mainframes, custom miniature packag-
ing to telecom systems. There are high
Tempus CBC 20
Introduction
With the growth of system circuit size
combined with the requirement to
manipulate larger amounts of data at
greater speeds, bus systems and their
interconnect components are being
pushed to their limits by the latest
microprocessors. The restrictions
imposed by using the DIN 41612 con-
nector and existing bus architecture are
now becoming evident. The electronics
industry also accepts the requirements
to obey metric dimensional practices for
future generations of components and
equipment.
density connectors already on the mar-
ket at present but none have been
designed with such a system approach
in mind and therefore the ability to
expand as required by technology.
TEMPUS CBC 20 contacts are laid out
in four and more rows on a 2 mm pitch
rather than three rows on a 0.1 inch
pitch. This gives the designer the facilli-
ty of 240 I/O lines in the same area pre-
viously occupied by a 96 way DIN
41612 style connector. Using TEMPUS
as opposed to DIN 41612 connectors
456 and more rather than 192 signal
positions may be obtained on a double
euroboard, over twice as many I/O
lines, giving the ability to address large
bus widths.
