The proper cable increases your machine availability

The choice of the proper cable or line for transmitting signals on your 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 deciding on the best sensors.
For example, the user determines which measuring principles are used for level measurement, which power supply should be provided to the machine 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 an interesting paradox in the automation technology ? a sensor is tested for highest demands to assure it meets the requirements of the application form, whereas a cable is merely regarded as a component which supposedly guarantees a trusted connection under all circumstances.
However, cables and connectors pose just about 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 due to the choice of an unsuited cable for the specific application. Principally, there is absolutely no patent remedy for determining which cable and which plug connector is best suitable for your application.
For example, flexibility demands for cables used 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 because of the lack of permanent leak tightness. For Definitely which are setup in factory buildings, the simplest cable materials with a straightforward M12 connector are used. 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 raise the option of your machine.
Using 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 would work 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. Take your time in specifying the right cable for your application. Take into account 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.
