Radio-frequency interference (RFI) and electromagnetic interference (EMI) can be greatly reduced with the proper use of contacts, fingerstock, and gaskets. The 4742PA51G00400 is a highly effective solution for shielding against both. This application field and working principle of 4742PA51G00400 are discussed below.

4742PA51G00400 is an EMC contact assembly with a highly effective shell construction which offers the highest level of RFI and EMI reduction for applications including industrial, telecom, marine, and aerospace. This contact is composed of three components: a contact pin, EMI contact, and a hybrid spring. As the contact pin passes through the EMI contact, the hybrid spring creates a flush connection, providing up to 90 dB EMI shielding and 50 dB attenuation. This contact is IP67 rated, providing superior protection from outside contaminants.

In addition to the aforementioned components, the 4742PA51G00400 also comes with a rugged fingerstock and gaskets that provide enhanced EMI shielding. The fingerstock is designed with serrations that provide an effective contact area, improving the overall performance of the contact. The gasket is made from nylon 66 that is corrosion-resistant, UV-stable, and highly temperature tolerant. Together they provide up to 80 dB of shielding and 40 dB attenuation.

To illustrate how the 4742PA51G00400 works, consider a common RFI/EMI scenario in which an external source produces electric or magnetic fields that can interfere with a device\'s operation. By installing the 4742PA51G00400, the contact pin passes through the EMI contact, creating an efficient shield that absorbs the source\'s interference. In order to ensure maximum performance, the fingerstock should be installed in close contact with the contact pin to ensure a consistent connection. The gasket helps to ensure a tight seal, preventing any contaminants from entering the connection and compromising the shielding.

The 4742PA51G00400 is an excellent solution for applications where maximum RFI and EMI shielding are required. The robust design and quality components ensure a reliable connection and superior shielding performance. This contact is ideal for industrial, telecom, marine, and aerospace applications.
