ERNI
Pre-Alignment Modules
Provides reliable connection, coding and grounding of plug-in cards
ERNI has developed a solution to the dilemma posed by high
pin-count hard-metric (HM) connectors and the need for preci-
sion connector mating combined with sufficient play between
subrack guide rails and printed-circuit board (PCB) cards. The
answer is ERNI’s pre-alignment module.
According to the IEC 61076-4-101 standard, a 2mm HM con-
nector may have hundreds of contacts. At the same time, the
plug-in board connectors and backplane connectors must mate
precisely in order to avoid damage. On the other hand, there
must be play between the cards and rails to avoid compression
stress on the PCB.
ERNI’s pre-alignment module consists of solid metal guides and
new guiding systems that offer several optional functions. For
example, there is a kit available with an integrated socket for
HM “coding” keys. Thus no coding on the connector side is
needed, which offers more room for signal contacts. In addition,
there are flattened pre-alignment pins designed to match their
mating connector counterparts. Using an octagonal pattern, it
will support eight additional coding options.
A further reasonable additional option is the electrical contact
model. Shielding is low restistant because of gold plating, and
therefore allows electric current to flow with 40A at 20°C

through a large diameter. A corresponding derating curve is
available. This large pin diameter enables a wide capture range
of >2mm. The PCB is adequately centred and guided as a
result of the appropriate length.
The pre-alignment pin with fastening thread is fastened on the
backplane and is available for PCB thicknesses of 2.5 to 6mm,
and 6 to 8mm. The guide bush is mounted on the daughter
card with an M4 or M5 screw. The PCB thickness for the
daughter card can be 1.6 to 3.5mm, or 3.5 to 5.5mm.
