Dear Readers,
You are holding the first plugin issue of 2011 in your hands. As always, this is also
an occasion to take a brief glance back as well as forwards. As a result of the solid
growth of the general industrial sector including the product groups Industrial,
Franco
Delvecchio
CEO
­Multi‑Contact
Automation, Medical and Test & Measurement together with the continuing strong
demand in the photovoltaic industry, the Multi-Contact group experienced a record
year in 2010. I should like to thank our loyal customers and partners for our good
business relations and the confidence they have placed in us, and last but not least,
the valued members of our staff for their enthusiasm and committed efforts.
Not so long ago, many of the things for which Multi-Contact now stands were not
even dreamt of: Its PV plug connector systems have proved themselves millions of
times over and generate a substantial part of MC’s business. Solar electricity at competitive prices and the growing share of renewable energy in the global energy mix
will continue to power the growth of the photovoltaic industry. As market leaders in
the cabling of solar modules, in order to keep abreast of the booming demand we
have again made large investments in the expansion of production with a more than
threefold increase in production capacity for PV connectors. Despite the significant
increase in output it still goes without saying that we meet the high quality and safety standards of the industry. With this in view, in 2010 investments were also made
in state-of-the-art testing facilities which make a substantial contribution towards
greater process reliability and the faster performance of prototype tests.
Safety is an important issue in all parts of the company as well as in everyday life,
and is assigned the highest priority by Multi-Contact. For that reason, in this issue
we highlight products in which this aspect comes particularly to the fore. In many
applications MC connectors guarantee greater safety for their users, their surroundings or the processes in which they are involved. On the other hand inferior copies
of our connectors can endanger the safety of users and result in high costs – which
is why Multi-Contact warns expressly against the use of copies. The safety of our
employees is also a matter of great concern for us, a fact which finds expression in
safety instruction courses in various fields and a well-trained works first aid team.
With the new environmental management system according to ISO 14001, we face
up to another important issue – the protection of the environment. MC-USA also
shows its commitment to sustainability and renewable energy by the installation of a
photovoltaic system on the roof of its new company building.
We can look forward to an exciting future and another successful, dynamic year.
I wish you an enjoyable read.
Yours sincerely
Franco Delvecchio

MC USA relocates to Windsor, CA
End of February 2011, Multi-Contact USA moved from Santa Rosa to larger quarters
in the nearby town of Windsor.
The 42,500-square-foot building is
located next to Windsor Town Green
in old Downtown. The new premises
are only a few minutes’ drive from the
previous location. Main reasons for the
relocation are the growing demand for
solar components and an expansion of
manufacturing in the U.S.
On the roof of the new U.S. headquarters, there will be installed a
205-kilowatt solar power system with
840 solar panels supplying most of
­Multi-Contact’s electrical needs.
Like other MC-Units globally, MC USA
is making a clear statement that it is

serious about renewable energies.
Later in the spring, MC-USA will host
a ribbon-cutting and inauguration
event of the new building. Members
of the Multi-Contact and Stäubli senior
­management will be expected to participate in this event. In July, MC-USA
will hold an official open house event
for friends, family, and the community.
