Measurement & high frequency technology

Signal transmission reliabiltity and long service life

Measurement and high-frequency technology imposes very high demands in terms of the accuracy and reliability of all the components used. This in turn imposes the highest demands on transmission of signals. LEONI cables and conductors guarantee signal transmission reliability and a long service life despite providing maximum flexibility. As a developer and producer of special cables and complete system solutions for the measurement and high-frequently technology sector, our products are specifically tailored to this industry’s requirements. Our products range from the smallest miniature cables through to sophisticated, application-specific hybrid cables. Our cables for high frequencies up to 40 GHz also provide, in addition to their high flexibility and low attenuation, precise surge impedance and specific capacity values. We guarantee reliable signal transmission even in mobile applications.

Our solutions:

  • single coaxial / triaxial cables
  • multi-pair coaxial cables
  • miniaturised coaxial cables
  • hybrid cables with integrated bus, signal and power supply conductors
  • miniaturised hybrid measurement cables
  • sensor cables
  • integrated measuring and image processing systems
  • microwave cables

Application example measuring systems

Round cable for portable, four-channel measuring systems on bridges

In this application, the bridge measuring device is fitted directly to the bridge and measures the vibration caused by the ongoing road traffic.

The cable used in this case must be resistant to chemicals and mechanically very robust. In addition, it has to have consistently low attenuation throughout its entire service life. Our round cable, which we developed specifically for this application, has consistent signal transmission properties, is just 6.4 mm thick and extremely flexible. It is resistant to chemicals and provides reliable measurement readings over a long term.

Application example sensor cables

Sensor cables for real-time remote monitoring of crop plants

The challenge in this application consists of the sensor cable for monitoring the plant’s water supply having to be fitted directly to the leaves.

The cable is exposed to such outside influences as temperature fluctuation and various media. We have developed an especially lightweight, miniaturised, 1.4 mm thick and shielded sensor cable. It is particularly resistant to such media as fertilizers and to UV rays.

Application example high-flex probe cable

High-flex probe cable for analysers

The challenge set for the miniaturised 18 GHz probe cable is that the signal transmission properties must remain absolutely consistent during movement.

Especially high cable flexibility is needed to enable easy and simple handling of the manually guided probe. This shielded miniature cable with a diameter of just 1.65 mm fulfils all the requirements and has been in successful use for years.
