The proper 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 device availability. Usually, when determining the instruments of machines and plants, a profound level of attention is given to choosing the right sensors.
For example, the user determines which measuring principles are employed 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 certain 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 the most frequent sources of error. This is often where unforeseen potential for increasing machine availability can be found. During my course of research I learned that in a high two-digit percentage of most 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 precise 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 found 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 Pay Zero , plug connectors are barely ever applied as a result of lack of permanent leak tightness. For machine tools which are create in factory buildings, the simplest cable materials with a simple M12 connector are employed. In this case, however, the usage 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 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 are the same and that any given cable with the sufficient number of wires would work for an application.
In Resourceful 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 connection to sensors and PLC must meet. An individually matched wiring concept supplies a measurable increase of the machine availability and higher safety during operation.
