In a world that runs on information and data, instrumentation cables are perhaps one of the most important cable types we deal with today.
The applications for instrumentation are many, but these are typically used to transmit voice and data. These cables are also used connecting instruments and electric equipment.
This is a broad category for instrumentation cable manufacturers with many types of cables.
Types of Control and Instrumentation Cables
They come in all shapes and sizes, from thin cables for walky-talkies to multicore cables for MRI machines.
It also means that manufacturers often supply various industries, from entertainment agencies and computing to industrial production.
With such wide applicability of the instrumentation cable, their construction is also far from typical.
Because most applications are different from others, most instrumentation cable manufacturers offer customisation of their products. The cable particulars depend on equipment size, power requirement and working conditions.
Several factors are considered when designing an instrumentation cable. The main concern here is to minimise the disruption of information or data while ensuring that the power requirements are met. These include:
Level of shielding
This is critical in minimising disruptions. The cables have a type of electromagnetic shielding that covers the cable underneath.
It prevents the emission of electromagnetic radiation from the cables while cutting out any electrical disturbances from reaching inside.

Material to be used.
This is important in ensuring that the cable can withstand its operating conditions. The material will also determine the quality of the transmission.
Manufacturers use different types of materials for jackets and insulation. These include EPDM, Neoprene, Silicon rubber, and Thermoplastic.
- EPDM has the advantage of flexibility over a varied temperature range.
- Neoprene, a type of synthetic rubber, has high resistance to flames, oil, and chemicals.
- Silicon rubber has great flexibility.
- Thermoplastic includes a vast array, including PE, PVC, and Teflon. These have the advantage of high flexibility with high resistance.
- Mica tape has a high-temperature resistance.
Multicore cables get their name from the multiple cores in their construction. The term multicore is used about the standard and not merely as an indication of the number of cables.
Number of cores
Conductors are usually made of copper because of their resistance to corrosion and high conductivity. Aluminium is also used often, apart from steel and clad.
From a few cores to multicore cables, ether is many instrumentation cables. This will depend on the equipment requirement.
Many buyers are particular about the colouring of cables, such as cable jackets and core colour codes.
Types of instrumentation cable by instrumentation cables manufacturers
Used in ARCNET networks, these cables are used for high-speed connection in the local area network connection between industrial computers.
Used in AS-Interface installations, most AS-I cables are flat cables. It utilises cable piercing technology for easy installation that does not have to be cut up before installation. The yellow cable communicates between the field device and scanner, while the black jacket cable is used to carry power.
These exchange communication in a Control Area Network (CAN). Widely used in the automobile industry, these cables are highly corrosion-resistant because of their hostile environment.
These are used in motion control networks. These cables are also highly resistant, and their application includes automotive and marine electronics.
Developed for automation in the industrial sector, Device Net was based on CAN structures. The cables connect devices like photoelectric cells, limit switches, manifolds, valve motor starters, operator displays, and drives to programmable logic controllers (PLCs) and personal computers.
Selecting the right wires & cables exporter must also be undertaken carefully. Given the high-tech and high-revenue nature of the electronics industry, the importance of the component industry also becomes important.
Fieldbus is an industrial networking system; hence, the cables connect typical industrial appliances like sensors, transducers, controllers and actuators. Like LAN systems, it uses multiple analogue and digital points. Typically, we need short but multiple cables for one operation.
These cables are meant for two-way communications between field devices and the control system. Applications include petrochemicals, refining, power generation, F&B and even pharmaceuticals.
Also known as NetBus cables, these are flexible Fieldbus cables. Apart from data transference, it is also used management and control of sensors.
These cables are used in PROFIBUS communications. These connect sensors, actuators and controllers in an industrial environment.
With such wide applications, instrumentation cable manufacturers often have to customise products according to the demands of their clients. From factory automation to petrochemicals, these cables are truly our information highways.
