RFI and EMI - Contacts, Fingerstock and Gaskets

The SG125375R-48 is an example of RFI and EMI contacts, fingerstock and gaskets. RFI/EMI stands for Radio Frequency interference/Electromagnetic interference. It is a type of equipment that helps reduce the transmission of electric signals between a device or appliance and its associated control system.It is essentially a series of about 50 contacts made from 0.625-inch ABS thermoplastic interconnect materials. The unique shape of the contact creates spring action, meaning it can flex to generate a reliable connection even when in the presence of harsh environmental conditions including EMI and vibration.The SG125375R-48\'s application field is best suited for interconnection to board-level mechanical protection in both commercial and military equipment. In addition, this contact can also be used in appliqué motor switching applications, although its smaller size can limit its ability to provide secure connection or operation control in certain motor switching applications.The working principle of the SG125375R-48 is relatively simple. Interfacing between a printed circuit board and an appliance, the contacts act as a switch. When the device needs to be powered up, a positive charge is generated from the appliance and travels through the contacts, which in turn activate the board. Similarly, the contacts then serve as a ground point when the device needs to be shut off. This switching action provides a secure connection and ensures electrical signals are minimized, resulting in reduced electromagnetic interference or noise.The SG125375R-48 also provides EMI shielding in addition to its ability to create an electrical connection between a device and its control strength. It achieves this by creating a Faraday Cage, an area of strong electric field insulation to protect both the board and the appliance from external radiated emission. This shielding technology helps to reduce static discharges that may have an effect on circuit boards, such as spikes or fluctuations.The SG125375R-48 features a unique shape, which offers several advantages. The unique shape ensures a strong connection for the appliance and the board as currents travel along the contact. Furthermore, the shape provides a better profile for electrical and thermal conduction. This helps to absorb shock and shock waves and reduce electrical noise.In addition, the shape also allows the contact to work better with smaller items or devices, such as interconnect wires, connectors, and switches. This is especially useful in devices meant for high-reliability operations, as it ensures a secure connection in spite of high shocks and vibrations.To sum it up, the SG125375R-48 is a contact that provides both electrical and mechanical protection in devices. Its unique shape ensures that it can create a reliable connection even in harsh environmental conditions and provide EMI shielding. Moreover, its shape also offers the advantage of working well with small items, making it perfect for high-reliability operations.
