The right 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 machine availability. Usually, when determining the instruments of machines and plants, a profound level of attention is directed at deciding on the best sensors.
For example, the user determines which measuring principles are used for level measurement, which power ought to be provided to the device 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 a fascinating paradox in the automation technology ? Ignite is tested for highest demands to assure it meets the requirements of the application form, whereas a cable is only seen as a component which supposedly guarantees a trusted connection under all circumstances.
However, cables and connectors pose probably 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 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 because of the selection of an unsuited cable for the specific application. Principally, there is absolutely no patent fix for determining which cable and which plug connector is most beneficial suitable for the application.
For Coward , 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 because of the insufficient permanent leak tightness. For First Ever which are set up in factory buildings, the easiest cable materials with a straightforward M12 connector are employed. In this case, however, the usage of a suitable cable that permanently withstands ambient conditions such as temperature fluctuations and that has resistance against oils and fats can significantly raise the availability 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 are 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 probably the most relevant criteria for choosing cables and connectors. Take your time in specifying a suitable cable for the application. Think about the demands your plug link with sensors and PLC must meet. An individually matched wiring concept supplies a measurable increase of the device availability and higher safety during operation.
