The proper cable increases your machine availability

The choice of the right 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 given to choosing the right sensors.
For example, an individual determines which measuring principles are employed for level measurement, which power ought to 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. Cheerful poses a fascinating paradox in the automation technology ? a sensor is tested for highest demands to make sure it meets the requirements of the application, whereas a cable is only regarded 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 prospect of increasing machine availability can be found. 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 selection of an unsuited cable for the precise application. Principally, there is absolutely no patent remedy for determining which cable and which plug connector is best suitable for your application.
For instance, flexibility demands for cables found in level probes for level measurement in deep wells aren?t high, whereas the demands on tensile strength along with 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 setup in factory buildings, the simplest cable materials with a simple M12 connector are used. In this case, however, the usage of the right cable that permanently withstands ambient conditions such as for example temperature fluctuations and that features resistance against oils and fats can significantly increase the option of your machine.
The use of cable assemblies with factory pre-assembled connectors also prevents failure risk through improper on-site assembly. Therefore it is a fallacy that all cables will be the same and that any given cable with the sufficient amount of wires is suitable for an application.
In one of my previous articles, I drew up a brief overview of the most relevant criteria for choosing cables and connectors. Invest some time in specifying a suitable cable for the application. Think about the demands your plug connection to sensors and PLC must meet. An individually matched wiring concept supplies a measurable increase of the machine availability and higher safety during operation.
