Introduction

4245PA51H00300 is a contact switch which belongs to the RFI and EMI - Contacts, Fingerstock and Gaskets category. It is mainly used as part of a low pass filter or EMI filter, and provides a reliable and cost-effective method of shielding against electromagnetic interference (EMI). 4245PA51H00300 is used in many applications, such as automotive, military, telecommunications, computing, and medical devices. In this article, we will discuss the application field and working principle of 4245PA51H00300.

Application Field

4245PA51H00300 is mainly used in two application areas: filter and switch. In filter applications, 4245PA51H00300 provides a low-frequency path that allows lower frequency electromagnetic radiation to pass, while blocking higher frequency radiation. This is particularly useful for EMI/RFI applications such as shielding cables and connectors. In switch applications, 4245PA51H00300 provides an on/off control mechanism for circuits or systems that are exposed to extreme levels of electromagnetic radiation. In addition to EMI/RFI applications, 4245PA51H00300 is also widely used in automotive, military, telecommunications, computing, and medical devices for further shielding against electromagnetic interference. For example, in automotive applications, 4245PA51H00300 is used to provide additional EMI shielding for fuel, ignition, and starter systems. In telecom and computing applications, 4245PA51H00300 is used to provide protection from EMI generated by radio frequency interference (RFI).

Working Principle

The working principle of 4245PA51H00300 is based on the principle of electromagnetism. The contact switch consists of a ferromagnetic core and two magnets, which are arranged in such a way that when a low frequency electrical signal passes through the contact switch, the two magnets will be attracted to each other and create a magnetic field. This magnetic field is then able to shield the circuit from higher frequency radiation.At the operational level, 4245PA51H00300 provides a low-pass filter and a switch. The low-pass filter allows lower frequency electromagnetic radiation to pass through, while blocking higher frequency radiation. The switch operates by closing the contacts when exposed to a certain level of EMI. Once the level of EMI is reduced, the contacts will open and the circuit will be able to absorb the lower frequency radiation.

Conclusion

4245PA51H00300 is a contact switch belonging to the RFI and EMI - Contacts, Fingerstock and Gaskets category. It is mainly used as part of a low-pass filter or EMI filter. In addition, 4245PA51H00300 can also be used in switch applications. The contact switch works based on the principle of electromagnetism and provides effective shielding against higher frequency electromagnetic radiation.
