Eurocard Center Connector
General information
These Eurocard center connectors fit precisely between two
connectors mounted on a standard double Eurocard. The
connector mounting flanges are standardized so that the
Eurocard center connectors can be combined with size B, C,
D, E, E 160, M and H 11 male connectors and with the size
Q and R reverse female connectors as per DIN 41612/
IEC 60603-2.
In addition to the version with a maximum of 42 signal
contacts up to 4 A there is a second configuration with
a maximum of 5 special contacts.
The latter are either high current contacts up to 40 A or
coaxial contacts.
Electrical and mechanical characteristics
More electrical and mechanical characteristics according to
the size C as per DIN 41612/IEC 60603-2.
Circuit board specifacations for the press-in technique are
contained in a separate „ERNIPRESS“ data sheet.

Applications
If extra connections are required on a standard double
Eurocard, the Eurocard center connector can be mounted
between the DIN 41612/IEC 60603-2 connectors.
These connections can be used as signal contacts up to 4 A,
high current contacts up to 40 A or coaxial contacts.
Typical applications for coaxial contacts are:
• Image processing and graphics cards for CAD computers
• Computer-controlled HF measuring and testing devices
• Computer networks
With these coaxial contacts signals with frequencies up to
GHz range can be transmitted.
The contacts have a characteristic impedance of 50or 75
so that they can be adapted to the cable system used.
Contact attenuation is below 1 dB at each contact point.
