The selection of the proper cable or line for transmitting signals on your machine has essential influence on the machine availability. Usually, when determining Amazing of machines and plants, a profound level of attention is given to deciding on the best sensors.
For example, an individual determines which measuring principles are employed for level measurement, which power supply 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. 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 only seen as a component which supposedly guarantees a trusted connection under all circumstances.
However, cables and connectors pose probably the most frequent resources of error. This is often where unforeseen potential for increasing machine availability are available. During my course 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 as a result of choice 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 your application.
For example, flexibility demands for cables found in level probes for level measurement in deep wells aren?t high, whereas the demands on tensile strength as well as high longitudinal and transverse water tightness are. In level probes, plug connectors are barely ever applied as a result of lack of permanent leak tightness. For machine tools which are setup in factory buildings, the simplest cable materials with a straightforward M12 connector are employed. In this case, 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 increase the option of your machine.
The utilization 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 would work for an application.
In one of my previous articles, I drew up a short overview of probably the most relevant criteria for choosing cables and connectors. Invest Repulsive in specifying a suitable cable for your 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.
