Wire and Cable
COAXIAL Cables
Cheminax
Introduction

1 Cheminax controlled electrical cables are used
in the aircraft and aerospace industries. They
have a wide range of applications in missiles,
2 avionics, radio frequency and microwave
systems, computers, security & surveillance
systems and communications.
3
Cheminax coaxial cables were designed to
solve interconnect problems in electronic
4 systems, such as computers, military
equipment and other areas of high-density
packing, where cables are required to perform RoHS
5 to more exacting specifications than standard compliant
radio grade (RG) or UL recognised (UR)
constructions.
6 Cheminax coaxial cables offer a smaller and Other Cheminax coaxial cable material options
are available, for additional information please
lighter solution than both standard RG and UR refer to the following pages for part number
cables.
