The proper cable increases your machine availability

The choice of the proper 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 amount of attention is directed at choosing the right sensors.
For example, an individual determines which measuring principles are used for level measurement, which power ought to be provided to the machine and which type 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 ? a sensor is tested for highest demands to make sure it meets the requirements of the application form, whereas a cable is merely regarded as a component which supposedly guarantees a reliable connection under all circumstances.
However, cables and connectors pose probably the most frequent resources of error. This is exactly where unforeseen potential for increasing machine availability are available. During my course 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 as a result of selection of an unsuited cable for the specific application. Principally, there is absolutely no patent remedy for determining which cable and which plug connector is best suitable for the application.
For Feeble , 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 insufficient permanent leak tightness. For machine tools which are create in factory buildings, the easiest cable materials with a simple M12 connector are employed. In this case, however, the usage of the right cable that permanently withstands ambient conditions such as temperature fluctuations and that features resistance against oils and fats can significantly increase the availability of your machine.
The application 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 amount 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 the demands your plug connection to sensors and PLC must meet. An individually matched wiring concept offers a measurable increase of the device availability and higher safety during operation.
