Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) are significant factors in the optimization of electronic product performance. Contacts, fingerstock and gaskets are used to minimize the effects of these electromagnetic fields, reducing their impact on system performance and reliability. From aerospace technologies to automotive components, electrical connections are necessary for communication, control and protection.

When constructing or upgrading an electrical device, contacts must be selected to create a reliable connection which also claims low contact resistance in order to minimize losses. EMI and RFI contacts offer the flexibility to achieve this balance, allowing the designer to tailor the connection to the application. Shielding contacts, such as the 4882PA51H01800 shielded or unshielded contact, are often utilized in order to attenuate the EMI / RFI energy that could disrupt the performance of circuit boards, switches and digital control systems.

The 4882PA51H01800 contact is designed for applications such as a power connections, ground connections, and connections to an electronic box. This contact is employed to reduce the amount of electromagnetic interference that can interfere with the device’s operations. The 4882PA51H01800 contact has a 0.5 mm pitch and a 0.7 mm mounting hole, making it compatible with most 6.5mm through-hole PCBs. The contact is constructed from brass with nickel plating and pre-formed steel fingers that are designed to resist deformation.

The 4882PA51H01800 contact works via the concept of EMI/RFI attenuation. By segmenting the signal transmission between two contacts, the 4882PA51H01800 contact creates a high impedance path that reduces the effectiveness of the EMI/RFI signal transmitted as current. This segmentation is achieved by using the steel fingers, which act as a two-way barrier between the contact surfaces. The spacing between these fingers creates an air gap, allowing for the EMI/RFI noise to be blocked, converted or dissipated. This attenuation process helps reduce the interference that can impact the performance and reliability of electronic systems.

The 4882PA51H01800 contact is also designed with a low-profile design for optimal electrical connections in tight spaces. It is designed to fit into limited space applications such as satellite systems, autos, helicopters, ships, and other areas where space is limited. The finger stock is designed to act as a mechanical spring, providing the necessary friction to maintain electrical continuity while allowing a reliable connection during shock and vibration.

In addition to the attenuation capabilities, the 4882PA51H01800 contact has contact points that are protected by a silicone gasket to further minimize EMI/RFI emissions. The silicone gasket helps to extend the life of the contact by isolating it from the environment, protecting it from corrosion and oxidation. It is also designed to dissipate the heat generated from the circuit as it passes through the contact.

The 4882PA51H01800 contact is a reliable and durable device designed for applications such as power connections, ground connections, and connection to electronic boxes, making it a popular choice for electrical designers. It offers superior EMI/RFI attenuation, is designed for use in tight spaces, and features a special silicone gasket for reliable and durable use. This contact provides superior signal integrity and reliability, improving system performance and reliability in any application.
