Connectivity Solutions
To our valued customers:
For over 80 years, Johnson Components and Cambridge Products have been providing our
electronics distributor and OEM customers with cost-effective, high-quality solutions for
connectivity. This catalog combines the product lines of Johnson Components and Cambridge
Products under the Johnson product line of
Emerson Network Power Connectivity Solutions.
In addition to combining these product lines, we have also combined several of our intercon-
nect businesses under the name
Emerson Network Power Connectivity Solutions.
We believe
this name not only reflects our traditional industry focus, but also better communicates the
additional resources that we can supply as part of Emerson Network Power.
Although our name is changing, our commitment to product quality and to excellent service
to our customers will not. Our combined connectivity product line will continue to focus on the
wireless, test/measurement, instrumentation, OEM and installer markets for data networks,
telecommunications, satellite, security, telemetry and CATV.
This catalog offers our customers new products such as the SMK (2.92mm) range of 40 GHz
connectors and non-magnetic connectors for the medical industry as well as extensive
enhancements to our existing product portfolio. It continues to provide comprehensive data
on our range of coaxial connectors, cable assemblies, hardware, tools and test products to
support your design and application needs and those of your customers.
Emerson Network Power Connectivity Solutions
is a global player with manufacturing, sales
and engineering presence in China, the United Kingdom and the United States to meet our
customers’ requirements around the world. Our goal is to continue to expand our product
offerings and capabilities to continue meeting your changing needs.
Thank you for allowing us the opportunity to serve you.
Best Regards,
