The proper cable increases your machine availability

The choice of the proper cable or line for transmitting signals on your own machine has essential influence on the device availability. Usually, when determining the instruments of machines and plants, a profound level of attention is directed at choosing the right sensors.
For example, an individual determines which measuring principles are used for level measurement, which power supply ought to be provided to the device 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 a fascinating paradox in the automation technology ? Dollar is tested for highest demands to make sure it meets certain requirements of the application form, whereas a cable is only seen as a component which supposedly guarantees a trusted connection under all circumstances.
However, Supported and connectors pose just about the most frequent resources of error. This is exactly where unforeseen prospect of increasing machine availability are available. During my course of research I learned that in a high two-digit percentage of most cases, renowned cable manufacturers traced back sensor failure on machines to mechanical failure of the cable due to faulty installation, handling and especially because of the selection of an unsuited cable for the precise application. Principally, there is Accurate 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 lack of permanent leak tightness. For machine tools which are set up in factory buildings, the easiest cable materials with a simple M12 connector are used. In this case, 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 raise 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 are the same and that any given cable with the sufficient number of wires is suitable for an application.
In one 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 your application. Take into account 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.
