S1761-46R is a type of contact used in RFI and EMI applications (Radio Frequency Interference/Electromagnetic Interference). It is part of the fingerstock family of contacts, and features a dielectric gasket for shielding. This article will explain the application fields and working principles of S1761-46R to help users better understand how the product works and identify the most appropriate application for the product.

Application Fields

S1761-46R contacts are primarily used in the installation and production of RFI and EMI protection technology. The contacts feature a dielectric gasket made of silicone rubber, which provides the product with excellent shielding capability against interference from radio transmission. Both the RFI and EMI applications involve the purposeful placement of the contents between two metal contacts in order to prevent the transmission of electrical current. The shielding of the dielectric gasket provides ample protection against such interference.

The contacts can be used in a variety of other applications as well. They offer excellent reliability and stability to provide strong electrical connections in high vibration environments, such as in the automotive industry. In addition, the contacts are suitable for use in a wide range of temperatures and climates, making them a popular choice for outdoor applications. Their general-purpose nature allows them to be used in a variety of fields, including electronics, telecommunications, automotive, and many more.

Working Principle

The S1761-46R contact has a simple working principle. It consists of three parts: a metal fingerstock contact, a dielectric gasket, and a spring substrate. The fingerstock contact is typically made from copper or aluminum, and is shaped to facilitate easy connection of two parts. The dielectric gasket is made of silicone rubber and is designed to provide effective shielding from electromagnetic interference. Lastly, the spring substrate provides the necessary tension to ensure contact between the metal fingerstock and the dielectric gasket.

When in use, the pressure applied to the contact causes the metal fingerstock to compress against the dielectric gasket, creating an electrical connection between the two parts. The gasket’s internal construction and flexibility allow it to maintain contact even under extreme vibration or shock. As a result, when properly installed, the contacts offer excellent reliability in its application.

Conclusion

S1761-46R contacts provide a reliable and cost-effective solution for RFI and EMI applications. The contacts are also suitable for a wide range of other applications due to their general-purpose nature. The contacts are easy to install and use, and feature a dielectric gasket for excellent shielding capabilities. By understanding the application fields and working principles of S1761-46R contacts, users can better identify the most appropriate application for the product.
