SG125250R-48 is a contact, fingerstock and gasket designed to help protect electronic equipment from interference with impulsive noise, electrostatic discharge (ESD) and electromagnetic interference (EMI). It is also known as a contact shield, ESD fingerstock and EMI gasket. This article will explain the application field and working principle of SG125250R-48.

Application Field

SG125250R-48 is designed to be used in applications that have the need for EMI and/or RFI protection. The contact design shields, filters, or absorbs the interfering signals and prevents them from entering the equipment. It is typically used in industrial, military, consumer electronics, aerospace, and telecommunication applications.

This contact is suitable for use in a wide range of indoor and outdoor electronic applications. It is particularly effective in protecting against electrical and radio-frequency interference, including high-frequency signals. It is especially useful in confined spaces, such as inside small electronic devices, where there may not be enough space to use traditional shielding methods.

Working Principle

SG125250R-48 works by creating an electrical barrier between the EMI source and the sensitive electronic components. The design of the contact consists of two layers; the upper layer is made of a conductive material, such as copper, and the lower layer is made of a dielectric material, such as plastic or rubber.

When the contact is placed between the EMI source and the sensitive electronic components, the conductive layer redirects the electromagnetic energy away from the equipment. At the same time, the dielectric layer absorbs the energy and spreads it across its surface, reducing the intensity and providing additional protection to the equipment.

In addition to being effective at EMI and RFI protection, SG125250R-48 is also very easy to install and requires no maintenance. It is also very durable and resistant to corrosion and wear.

Conclusion

SG125250R-48 is a contact, fingerstock and gasket that is used for providing effective EMI and RFI protection for electronic equipment. It works by creating an electrical barrier and absorbing and spreading the interfering energy across its surface. It is easy to install and requires no maintenance, and is durable and resistant to corrosion and wear.
