Electrical feedthroughs are used to lead measuring, control and regulating signals into or out of the vacuum. New in our product range are SUB-D feedthroughs, which are characterised by a high number of contacts in a small space. In addition to SUB-D feedthroughs, there are a number of other feedthroughs for transferring electrical signals into the vacuum, which can be selected depending on the operating conditions of the vacuum application. Specification features are, for example, voltage and the number of contacts.
When choosing a suitable feedthrough, attention should also be paid to the connection on the atmosphere and vacuum side. Some feedthroughs are pluggable on both sides or on one side. Others, however, are connected by crimp contacts, plug-in contacts or even terminals.
It is essential to observe the operating temperature of the electrical feedthrough, otherwise damage may occur. For voltages above 300V, it must also be taken into account that the dielectric strength depends on the surrounding medium and the pressure.
According to Paschen's law, the lowest dielectric strength occurs in a pressure range between 0.1 mbar and 1 mbar. For voltages above 300V, please keep the plug connections free of voltage during pumping.
In many applications, special configurations deviating from the standards are required, e.g. special flanges with a combination of different electrical feedthroughs, combinations with other vacuum components, etc. In addition to a stock of common configurations, customised special configurations can be realised with short delivery times.
