​The 4787PA51H08400 is a specialist contact spring designed for applications involving radio frequency interference (RFI) and electromagnetic interference (EMI). It is a standard spring-type contact, made of zinc-plated steel and chrome-nickel steel, and is often used in applications such as contacts, fingerstock and gaskets. It provides a secure connection between two electrical components, preventing unwanted interference and protecting sensitive electronic components from damage.

The 4787PA51H08400 contact spring has a male thread and is usually available in two sizes. The smaller size has a thread diameter of 8.0 mm, while the larger size has a thread diameter of 10.7 mm. This allows it to be used for a wide range of applications, including making contacts with surface mount and through-hole components.

The working principle of the contact spring is relatively simple. The two metal threads are positioned closely together so that they make contact when the spring is compressed. When the threads are brought into contact, an electrical connection is formed, allowing the current to flow from one component to the other. This contact is kept secure when the spring is compressed, because the tension in the spring keeps the two threads in contact.

The 4787PA51H08400 contact spring is most commonly used in applications that require a reliable contact and protection from RFI and EMI. It is often used as part of a fingerstock, allowing the device to provide an electrical connection and protect against interference. Additionally, it is commonly used as a gasket, providing a waterproof seal and anti-corrosion protection. The contact spring can also be used to create mechanical contacts with surface-mount and through-hole components.

Overall, the 4787PA51H08400 contact spring is an ideal solution for applications involving RFI and EMI. It is designed to be reliable and long-lasting, and is available in two different sizes to suit a wide range of applications. It is also easy to install, making it an ideal choice for projects that require a secure and reliable connection.
