Comparison of 2.0 mm systems
For many years board-to backplane connectors
were dominated by DIN connectors with a pitch of
2.54 mm. The advances of new designs in recent
years have migrated to 2.0 mm pitch connectors.
However, today there are three separate and non-
compatible 2.0 mm style connector families avail-
able on the market: Futurebus+ style, HDM
hard metric style.
Several years ago Futurbus+ and telecom applica-
tions standardised on a modular 2.0 mm connector
using of increments of 12 mm.These connectors are
currently undergoing IEC standardisation (IEC
61076-4-104). They are also specified for Industrial
PCI systems.
Another 2.0 mm connector specification available
today is commonly referred to as HDM
or VHDM. These connectors come in 22 mm and 46
mm increments.
This proprietary system is not standardised there-
fore, unable to provide a high degree of intermata-
bility.
For high speed applications like CompactPCI
hard-metric connector, such as har-bus
HARTING, was chosen. It is a modular 2 mm
connector using increments of 25 mm. Compact-

and
the
connectors will not assemble to a 100 mm card
height because of space needed for guide rails. The
type B connector is therefore shortened to 22 rows
or 44 mm length. J4/P4 and J5/P5 on 6U cards are
mirror images of J1/P1 and J2/P2 respectively. The
centre connector J3/P3 on 6U has 19 rows of pins.
This 19 row version is also used as the centre
connector J0/P0 on 6U VME boards.
The popular configuration of 2.0 mm hard metric
connectors are 5 rows of signal contacts and one or
two rows of outer shield or ground contacts. The
increase in pin-count over the popular DIN connec-
tor (IEC & EN 60603-2) is quite significant, 96 to 240
contacts. The enhanced or 5-row DIN compatible
connector (har-busâ 64) originated by HARTING,
has 160 contacts on a 2.54 mm pitch.
The IEC 61076-4-101 hard metric connector has
been designed for high-speed applications with
appropriate shielding options. It is specified for
CompactPCI
cations. Further standardisation is being developed
by VITA as a mechanical practice guide, VITA 30
Draft standard.
