RF and EMI - Contacts, Fingerstock and Gaskets

Contacts are one of the most important components in electronic systems, and they are utilized for applications where signal transmission and/or electrical energy needs to be passed between two components. Contacts can range from the most basic switch contacts for transmitting a signal when pressed to the more complex for transmitting power and signals between two circuits. Most Electronic systems have gaskets and other shielding elements to ensure the highest performance of the system under conditions where Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) must be considered.

8911014543 application field and working principle

The 8911014543 contact is a flexible, high-performance electrical contact designed for use in high-speed signal applications. It is designed for low contact resistance, high current capacity, and excellent signal performance, making it a suitable choice for applications such as RF transmitters and receivers. It features a low-profile design and is easy to install and versatile, making it an ideal contact for a variety of electronic systems.

The 8911014543 contact utilizes a special type of finger stock wrapped in a flexible insulation layer to ensure that a reliable and low-resistance connection is maintained between its two contact points. The insulation layer helps prevent potential contact points from making unintentional contact with any other conductive surfaces. The finger stock features a special contact surface that is able to transmit a signal when two similar features pass by each other. This type of contact is commonly used in high-speed signal applications, such as RF and EMI shields, and helps ensure minimal signal distortion when high speeds are reached.

The 8911014543 contact is most commonly used with a shielding gasket to help reduce EMI and RFI levels. The gasket is typically made from a ferromagnetic material that surrounds the contact in its installed orientation on a printed circuit board and helps to reduce the amount of interference that the contact can receive, or radiate. Gaskets also help protect the contact from physical damage and electromagnetic energy, which can be harmful to the contact and its signal performance and add cost to the overall design of the system.

In addition to the shielding gasket, the 8911014543 contact also features an attached shield plate to help further reduce EMI and RFI levels. The shield plate is a plated metal plate attached to the bottom of the contact, which surrounds the contact points to help reduce interference from radiating and entering the contact’s environment. The shield plate also helps provide protection from physical damage to the contact, such as wear on the contact surface, and can help reduce the cost of the overall PCB design.

In summary, the 8911014543 contact is a high-performance, low-profile contact designed for use in applications such as RF and EMI shields. It features a special type of finger stock wrapped in a flexible insulation layer, and is often used with a shielding gasket and shield plate for optimal signal performance and EMI and RFI reduction. The contact’s versatility and low-profile design make it an ideal choice for applications such as RF transmitters and receivers.
