Low-Noise Cables Thermax Low-Noise cables minimize triboelectric noise generated by cable movement, as well as providing superior shielding to protect signals from external interference. These cables are ideal for use with piezoelectric accelerometers or other sensitive transducers, or other applications with low-power signals and/or electrically noisy environments. They are also used in airborne EVM (Engine Vibration Monitoring) systems, with approvals from many major aerospace manufacturers. The cables shown below are just a few examples of our low-noise cable expertise. Many other combinations of materials and construction can be used to produce a low-noise cable that will fulfill your needs; please contact your Thermax representative with your requirements.
