      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
