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 choosing the right sensors.
For example, the user determines which measuring principles are used for level measurement, which power ought to be provided to the machine and which kind of signal transmission should be used. Usually, Quality shown in the wiring schemes as simple connection lines between sensor and SPS are problematic. Confessions poses a fascinating paradox in the automation technology ? a sensor is tested for highest demands to make sure it meets certain requirements of the application form, whereas a cable is only regarded as a component which supposedly guarantees a trusted 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 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 because of faulty installation, handling and especially because of the selection of an unsuited cable for the specific application. Principally, there is no patent fix for determining which cable and which plug connector is most beneficial suitable for the application.
For instance, flexibility demands for cables used in level probes for level measurement in deep wells aren?t high, whereas the demands on tensile strength together with high longitudinal and transverse water tightness are. In level probes, plug connectors are barely ever applied because of the lack of permanent leak tightness. For machine tools which are set up in factory buildings, the easiest cable materials with a straightforward M12 connector are used. In this instance, however, the use 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 raise the option of your machine.
The application of cable assemblies with factory pre-assembled connectors also prevents failure risk through improper on-site assembly. It is therefore 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 one of my previous articles, I drew up a brief overview of probably the most relevant criteria for choosing cables and connectors. Invest some time in specifying a suitable cable for your 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 device availability and higher safety during operation.
