Elcon CROWN EDGE Card Edge-style
High Current Connectors
CROWN EDGE is a board-to-board power interconnect solution
that uses Elcon high performance Crown contact technology
configured to mate directly
with a printed circuit board
edge or — for higher
currents — with a solid bus
bar. Power, signal and mixed
contact modules can be
combined and mounted end-
to-end to meet the
requirements of the
application.
High-current Card Edge Interface
CROWN EDGE uses Elcon’s proven Crown
contacts that provide multiple points of
contact for high current, and low voltage
drop and minimal heat generation. The
desired current rating for any given
application can be achieved by bussing
multiple contacts or even modules. For
even higher currents, CROWN EDGE can be
mounted onto a bus bar, and mate directly
with a bus bar tab. Optimum interface to
the mounting PC board is achieved through
five termination tails.
Flexible Modular Design
To make easy work of power distribution
design, CROWN EDGE is available in
modules of 2 and 3 contact segments, each
of which may have power or signal
contacts or a combination of both in a
single module. Modules can be placed
end-to-end for assemblies up to 8"
(203.20 mm) long. Custom molded
configurations are possible on high-
volume projects. Consult Elcon for details.
Versatile Power Arrangements
Opposing contacts are isolated, so power
connections at different voltage levels can
be on one side of the board, with ground
or power return on the other side.
True Hot Plug Support
CROWN EDGE power modules that support
current interruption under load as defined
by safety regulatory agencies are also
available. These true hot
plug modules allow
current interruption
under load by
incorporating a contact
design that restricts the
Elcon True
Hot Plug Contact
effects of arcing to areas
that do not compromise the integrity of the
connection when mating with a metal blade
or bus bar tab. See HOT PLUG
REQUIREMENTS on last page for details.

CUSTOM SOLUTIONS
Non-standard Modules
In case the standard CROWN EDGE modules do not meet
your design requirements, Elcon has the capability to
mold any combination of power and signal contact layouts
in 2 and 3 segment modules.
Application-specific Custom Designs
Elcon has a long history of designing and building
application specific custom connectors, and CROWN EDGE
is no exception. A one-piece CROWN EDGE insulator,
instead of a combination of several modules, provides
a more robust interconnect design, as well as cost
savings in high volume projects. Consult
Elcon for details.

Current (A)
Current rating for any given application will depend, among
other things, on the module combination, PCB copper trace
volume, and internal equipment temperature/air flow. Mounting
and mating to a bus bar will increase current ratings.
Compliance with Current Interruption Requirements
Hot plug CROWN EDGE modules are available for applications
that require current interruption as defined by safety regulatory
agencies. These power-only modules have been
evaluated and recognized by Underwriters
Laboratories for current interruption up to
50 cycles as per the UL1977 standard. For
more details, see HOT PLUG REQUIREMENTS
on last page.
