The proper 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 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 employed for level measurement, which power should be provided to the device and which type of signal transmission ought to be used. Usually, Pummel 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 assure it meets certain requirements of the application, whereas a cable is only seen as a component which supposedly guarantees a reliable connection under all circumstances.
However, cables and connectors pose the most frequent resources of error. This is exactly where unforeseen potential for increasing machine availability are available. During Alienated of research I learned that in a higher 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 selection of an unsuited cable for the precise application. Principally, there is no patent fix for determining which cable and which plug connector is best 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 in addition to high longitudinal and transverse water tightness are. In level probes, plug connectors are barely ever applied due to the lack of permanent leak tightness. For machine tools which are set up in factory buildings, the simplest cable materials with a straightforward M12 connector are employed. In cases like this, however, the use of the right cable that permanently withstands ambient conditions such as for example temperature fluctuations and that has resistance against oils and fats can significantly increase the option of your machine.
Using cable assemblies with factory pre-assembled connectors also prevents failure risk through improper on-site assembly. It is therefore 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. Take into account the demands your plug link with sensors and PLC must meet. An individually matched wiring concept offers a measurable increase of the device availability and higher safety during operation.
