Coaxial cable is one of the simplest form of electrical cable in cable assemblies. It has an inner conductor which is insulated by a dielectric insulating layer enclosed by an outer plastic sheath. The insulating dielectric medium is usually polyvinyl chloride (PVC) covering the copper core of the coaxial cable. The material used for insulation of cable assemblies is an insulator.
Insulators are used in electrical equipment to support and separate electrical conductors without allowing to pass current through themselves. An insulating material used in bulk to wrap electrical cables or other equipment is called insulation. However, there are certain parameters that helps to decide the performance and classification of electrical cable assemblies. Some of the basic parameters are capacitance, resistance, and inductance.
Micro Coaxial Cable as by its name is small in size but is similar to coaxial cable. Micro Coaxial Cable conducts electrical signal using an inner conductor, surrounded by an insulating layer and all enclosed by a shield.
Micro-Coax comes in two different capacitance ranges named as normal capacitance and low capacitance cable. Following is the technical specification for normal capacitance micro coaxial cable.
Normal Capacitance Micro Coaxial Cable has a linear capacitance that ranges to 95pF/m ± 10 pF/m. It is very flexible with extremely good mechanical behavior. It has the ability to withstand miscellaneous sterilization processes. Its continuous operating voltage is 24 volts and has an operating temperature ranging from – 50°C to + 200°C.
Micro coaxial cables are used in a range of consumer devices, military equipment. It is also in ultrasound scanning equipment and its cable assemblies. Micro coaxial cable designs enable reduced size, light weight and increased flexibility for ultrasound applications. It helps to deliver high signal quality using true coax cable assemblies in acoustic applications where cross talk, bandwidth and attenuation affect performance.
