Defi nitions
Connectors according to IEC 61076-4-101
The hardmetric connector system ept hm 2.0 was developed and manufactured
according to the international standard IEC 61076-4-101. Thus the user can rely on
a worldwide standard for the connection of printed circuit boards using connec-
tors with a large number of contacts. The printed circuit boards can be exchanged
between systems without diffi culty. Important parameters such as the fi xing,
shielding and coding of the printed circuit boards are compatible regardless of the
individual application.

The grid
ept hm 2.0 connectors are designed
with a 2 mm metric grid. They can be
easily connected in series to form a
continuous 2 mm grid. This grid pattern
is advantageous when creating a print-
ed circuit board since no space is lost in
the individual connector modules.

Connecting modules
The ends of the insulator material are
chamfered to simplify the connection of
additional modules and avoid twisting
the connectors. The chamfers ensure
the exact positioning on the printed cir-
cuit boards and stabilize the modules.

Coding
The connectors must be coded in a
modern BUS system to avoid mixing up
the printed circuit boards. The possibil-
ity of coding has already been defi ned
in the IEC 61076-4-101.
"Coding keys" can be manually snapped
onto the multi-function block of the con-
nector types A, D, L and M. The differ-
ent inserts are color-coded and can thus
be kept apart.

Multi-function block
The modules A, D, L and M are
equipped with a multi-function block.
This in turn can be equipped with the
coding keys. The molded guides ensure
the correct alignment of the male and
female connectors to each other and
they offer anti-twist protection before
contacting.
The coding keys can be inserted or
withdrawn using a simple insertion or
withdrawal tool.

Contact lengths of the mating and
termination side
ept offers three different lengths for
the front and four different lengths
for the rear side. The different contact
lengths are necessary because certain
signal or ground contacts need to be
the fi rst to be connected/disconnected
when adding/removing a module.
The 11.25 mm long contacts are mainly
required for the shielding rows z and f.
