Ribbon Twin-Ax Jacketed Cable Description
This 2.0 mm ribbon twin-ax uses individually extruded FEP primaries. Two conductors are pulled parallel and taped with PTFE to increase common mode impedance. Each pair is braided with silver plated copper wire and then extruded into a ribbon cable.

Hitachi Cable Manchester is making every effort to provide Lead free and Cadmium free products to help protect our environment. To this end Hitachi Cable Manchester, Inc. has adopted RoHS (Restriction of Hazardous
Substances) as its standard. Hitachi's website Eco-Index is designed to inform the interested user of contents of various restricted or banned elements in terms of parts per million. In most cases, the numbers stated are from actual lab tests using the acid digestion method, considered to be the most severe measurement of analyzing content of restricted and banned elements. It is Hitachi's goal to be 100% compliant to European RoHS, including the removal of the Deca-BDE exemption dated July 1, 2008.
