The right cable increases your machine availability

The selection of the proper cable or line for transmitting signals on your own machine has essential influence on the device availability. Usually, when determining Covert of machines and plants, a profound quantity of attention is directed at choosing the right sensors.
For example, the user determines which measuring principles are used for level measurement, which power ought to be provided to the machine and which kind of signal transmission ought to be used. Usually, the cables shown in the wiring schemes as simple connection lines between sensor and SPS are problematic. This poses an interesting paradox in the automation technology ? Vilified is tested for highest demands to assure it meets certain requirements of the application, whereas a cable is merely regarded as a component which supposedly guarantees a trusted connection under all circumstances.
However, cables and connectors pose one of the most frequent sources of error. This is often where unforeseen potential for increasing machine availability are available. During my span of research I learned that in a high two-digit percentage of all cases, renowned cable manufacturers traced back sensor failure on machines to mechanical failure of the cable due to faulty installation, handling and especially due to the choice of an unsuited cable for the precise application. Principally, there is absolutely no patent fix for determining which cable and which plug connector is most beneficial suitable for the 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 high longitudinal and transverse water tightness are. In level probes, plug connectors are barely ever applied because of the lack of permanent leak tightness. For machine tools which are setup in factory buildings, the easiest cable materials with a straightforward M12 connector are used. In this case, however, the use of the right cable that permanently withstands ambient conditions such as temperature fluctuations and that has resistance against oils and fats can significantly raise the option of your machine.
The usage of 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 would work for an application.
In another of my previous articles, I drew up a brief overview of probably the most relevant criteria for choosing cables and connectors. Invest some time in specifying a suitable cable for your application. Think about the demands your plug connection to sensors and PLC must meet. An individually matched wiring concept offers a measurable increase of the machine availability and higher safety during operation.
