Miniature and Micro-Miniature Coaxial Cables

Miniature coaxial cable requires precision equipment and a depth of expertise that has been a hallmark of ours since the beginning.

Miniature, micro-miniature, and ultra micro-miniature coaxial cable from New England Wire meets the demanding requirements of the medical and industrial world with custom options for the center conductor, dielectric, shield, and jacket. Examples include high strength alloy conductors for superior flex life and foamed dielectrics for reduced size and attenuation. By utilizing high quality low dielectric constant materials, we are able to reduce size without sacrificing signal integrity. In addition, we can combine multiple coaxes with other components into larger composite cable.

  • Conductors
    • Our full range of conductor materials are available including bare copper, plated copper, and high strength alloy
    • Typically stranded for improved flexibility
    • Miniature (24-32 AWG), Micro-Miniature (34-44 AWG), and Ultra Micro-Miniature (46-50 AWG) sizes are available
  • Dielectric
    • Selected based on electrical, temperature, and size requirements. Materials include:
      • Polypropylene
      • FEP
      • PFA
      • ETFE
