The MICTOR connector
family is based on the
microstrip concept of two
rows of signal contacts
divided by a center power
ground plane. MICTOR
connectors are mother-
board and daughtercard
compatible and include
designs for cable-to-board
applications.
Various mated heights are
available for parallel board-
to-board systems. Custom
stacking heights can be
provided. The MICTOR
connector family is avail-
able in 0.64 [.025] center-
lines and in sizes ranging
from 38 signal positions to
266 positions (in increments
of 38 positions). There is a
discrete ground bus every
12.7 [.50] of the connector
length, which can be
assigned to either power or
ground in any combination.
Redundant interfaces on
every signal line provide
added reliability. Two plating
options are available to
meet the needs of various
applications.
The housing material is
a liquid crystal polymer,
compatible with infrared
and forced air convection
operations.
The connector system uses
the solid ground bus
between the rows of signals
to provide low crosstalk and
excellent high-speed signal
characteristics.
