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 machine availability. Usually, when determining the instruments of machines and plants, a profound amount of attention is given to choosing the right 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 should be used. Usually, the cables shown in the wiring schemes as simple connection lines between sensor and SPS are problematic. This poses a fascinating paradox in the automation technology ? a sensor is tested for highest demands to assure it meets certain requirements of the application, whereas a cable is only regarded as a component which supposedly guarantees a reliable connection under all circumstances.
However, เพรสเชอร์เกจ and connectors pose just about the most frequent resources of error. This is exactly where unforeseen potential for increasing machine availability are available. 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 as a result of choice of an unsuited cable for the precise application. Principally, there is absolutely no patent remedy for determining which cable and which plug connector is most beneficial suitable for your 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 high longitudinal and transverse water tightness are. In level probes, plug connectors are barely ever applied because of the insufficient permanent leak tightness. For machine tools which are set up in factory buildings, the simplest cable materials with a simple M12 connector are used. In this instance, however, the usage of the right cable that permanently withstands ambient conditions such as 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. Therefore it is a fallacy that 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 brief overview of the most relevant criteria for choosing cables and connectors. Take your time in specifying the right cable for your application. Think about the demands your plug connection to sensors and PLC must meet. An individually matched wiring concept offers a measurable increase of the device availability and higher safety during operation.
