The right cable increases your machine availability

The selection 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 directed at choosing the right sensors.
For example, an individual determines which measuring principles are employed for level measurement, which power should be provided to the machine 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. Jealous 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 form, whereas a cable is only regarded as a component which supposedly guarantees a reliable connection under all circumstances.
However, cables and connectors pose one of the 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 all cases, renowned cable manufacturers traced back sensor failure on machines to mechanical failure of the cable because of faulty installation, handling and especially due to the choice of an unsuited cable for the specific application. Principally, there is no patent remedy for determining which cable and which plug connector is best suitable for the 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 and also high longitudinal and transverse water tightness are. In level probes, plug connectors are barely ever applied due to the insufficient permanent leak tightness. For machine tools which are set up in factory buildings, the simplest cable materials with a straightforward M12 connector are employed. In this case, however, the use of a suitable cable that permanently withstands ambient conditions such as temperature fluctuations and that has resistance against oils and fats can significantly increase the availability 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 cables will be the same and that any given cable with the sufficient amount of wires is suitable for an application.
In another of my previous articles, I drew up a brief overview of probably the most relevant criteria for choosing cables and connectors. Take Astonishing in specifying a suitable cable for your application. Think about the demands your plug connection to sensors and PLC must meet. Anxious matched wiring concept offers a measurable increase of the machine availability and higher safety during operation.
