Radio Frequency Interference (RFI) and Electro Magnetic Interference (EMI) contacts, fingerstock and gaskets are contact devices used to help reduce the spread of electro magnetic waves along conductive pathways. They are frequently used in industrial and military applications to provide high levels of electrical performance, noise immunity, and protection from RFI and EMI. In this article, we will look at one such contact: the 0077008617, as well as its application field and working principle.

Application Field

The 0077008617 contact is an RFI and EMI contact designed primarily for use as an :interconnect for high-speed communications in harsh environments, including those containing high levels of electro magnetic interference and frequencies. The device is also specifically designed to be used in high vibration and shock environments as its design allows it to provide superior electrical performance in such conditions.

The 0077008617 contact is also suitable for use in high current and voltage applications such as providing low-resistance connections between power cables and circuit boards. It can also provide a reliable connection for sensitive signal paths on printed circuit boards, as it has extremely low contact resistance to prevent distortion and reduce noise.

The contact is also used in the defense, avionic and aerospace industries, which require reliable interconnects that can cope with harsh environments, such as in satellites, missiles, and other space vehicles. Additionally, the contact has been tested to comply with MIL-SPEC standards and NASA requirements, making it suitable for use in defense and aerospace industries.

Working Principle

The 0077008617 contact utilizes a two part metal contact design, which features a high performance outer spring and an inner contact button that provides a low insertion force. The spring is composed of high performance wall construction and features a high strength compliant inner core for superior resistance to RFI and EMI. The contact also includes a double contact point, which provide reliable electrical connection with low resistance to ensure a low insertion force.

The inner contact button is constructed from stainless steel and includes a precision machined tip. It is designed to make reliable contact with the mass of the contact and to provide a high contact pressure with the mass. The contact provides optimum contact force while the inner spring provides constant tension for low insertion force when making a connection.

The contact also features a compliant radius at the top of the contact, which ensures consistent contact performance throughout the length of the contact. This radius also helps to minimize scratching or fretting when making contact.

In addition to providing superior electrical connection, the 0077008617 contact also has excellent abrasion and resistance to corrosion, making it suitable for both harsh industrial and military environments as it can withstand corrosive elements in the atmosphere.

Conclusion

The 0077008617 contact is a reliable and high performance contact for creating low resistance connections between two conducting surfaces. Its two part design provides low insertion force and superior electrical performance in harsh environments. The contact is suitable for use in high current and voltage applications in the defense, avionic, and aerospace industry, as it is compliant with both MIL-SPEC and NASA standards. Additionally, it is also resistant to abrasion and corrosion, making it suitable for harsh industrial and military applications.
