On January 21, 2022, the LEONI Business Group Industrial Solutions was acquired by BizLink Holding Inc.. This also includes our business activities in the market Machinery & Sensors.
This website [hosted at leoni.com] remains available until 21 July 2022.
Our business will continue as usual under a new name. You will be able to reach your contact persons as usual using the contact details you are familiar with.
Diameter and transmission optimised
LEONI has the sophisticated extrusion equipment for precise physical foaming of polyethylene (PE), during which the dielectric is precision foamed with nitrogen gas. We are among the few cable manufacturers who can, by means of taping technology, produce dielectrics of expanded polytetrafluorethylene (ePTFE) with a dielectric constant of up to 1.3 and outstanding mechanical properties.
These coaxial cables can be made in versions miniaturised with a diameter down to 0.3 mm. All coaxial cables can be integrated in both round and ribbon cables. LEONI produces multi-coax round cables with up to 512 individual coaxes, which are used in industry as well as medical equipment.
Coaxial cables transmit electrical signals and are sometimes subject to extreme demands, e.g. in terms of suitability for high frequency or signal propagation times. The cables’ construction has a crucial influence on these transmission properties.
High quality, silver-plated copper or copper coated with steel wire is normally used for the inner conductor of tailor-made coaxial cables. High-strength copper alloys are used to combine high mechanical resistance with extremely long flexlife.
The dielectric, which is a key component of the coaxial cable, is made primarily from polyolefins and fluoroplastics. These materials boast minimal HF loss and outstanding processability. They also make it possible to achieve the smallest cable diameter.
Advantages at a glance:
- excellent electromagnetic shielding, e.g. through the combination of shielding different shielding technologies
- outstanding electric transmission characteristics, e.g. reflection attenuation through inline Fourier analysis during the extrusion process
- extremely stable and consistent designed dielectrics through skin-foam-skin (LEONI cell) extrusion
Advantages of miniaturised solutions:
- smaller diameter with prescribed attenuation
- weight saving
- extremely fast transmission times up 85 % of the speed of light
- longer service life thanks to slimmer and more flexible structures
- broad product range with diameters from 0.3 to 20 mm
- minimal signal propagation time differences
- frequency range up to 20 GHz
- optimised electrical properties combined with smallest diameter
