The right cable increases your machine availability

The choice of the right cable or line for transmitting signals on your machine has essential influence on the machine availability. Usually, when determining the instruments of machines and plants, a profound quantity of attention is directed at choosing the right sensors.
For example, an individual determines which measuring principles are employed for level measurement, which power supply should be provided to the device and which type of signal transmission should be used. Usually, the cables shown in the wiring schemes as simple connection lines between sensor and SPS are problematic. This poses a fascinating paradox in the automation technology ? a sensor is tested for highest demands to assure it meets the requirements of the application form, whereas a cable is only seen as a component which supposedly guarantees a trusted connection under all circumstances.
However, cables and connectors pose one of the frequent resources of error. This is often where unforeseen prospect of increasing machine availability are available. During my course of research I learned that in a higher two-digit percentage of most cases, renowned cable manufacturers traced back sensor failure on machines to mechanical failure of the cable because of faulty installation, handling and especially as a result of choice of an unsuited cable for the precise application. Principally, there is no patent remedy for determining which cable and which plug connector is most beneficial suitable for your application.
For example, flexibility demands for cables found in level probes for level measurement in deep wells aren?t high, whereas the demands on tensile strength and also high longitudinal and transverse water tightness are. In level probes, plug connectors are barely ever applied as a result of insufficient permanent leak tightness. For machine tools which are set up in factory buildings, the easiest cable materials with a straightforward M12 connector are used. In this instance, however, the use of a suitable cable that permanently withstands ambient conditions such as for example temperature fluctuations and that features resistance against oils and fats can significantly increase the availability of your machine.
Using cable assemblies with factory pre-assembled connectors also prevents failure risk through improper on-site assembly. Therefore it is a fallacy that cables will be the same and that any given cable with the sufficient number of wires is suitable for an application.
In another of my previous articles, I drew up a short overview of the most relevant criteria for choosing cables and connectors. Invest some time in specifying the right cable for the application. Think about Cataclysmic with sensors and PLC must meet. An individually matched wiring concept offers a measurable increase of the device availability and higher safety during operation.
