Radio frequency interference (RFI) and electromagnetic interference (EMI) prevention is of utmost importance for the consistent and reliable functioning of electronic and electrical equipment. The 4056PA51G00137 is designed to provide RFI/EMI prevention through electrical contact, fingerstock and gasket assembly. The contact is certified to MIL-Q-9858 and MIL-S-81703 specifications for electrical contacts quality.

The 4056PA51G00137 RFI/EMI contact is suitable for a variety of uses in the commercial and military electronics markets. It has a variety of common applications such as power supplies, connectors, and cable assemblies to name a few. The contact can also be used for connectors, cable assemblies, microwave ovens, and a host of other products where reliable and consistent EMI/RFI shielding is a necessity.

The assembly is comprised of a 30-micron-thick expandable, electroplated copper fingerstock with a wide surface area for positive contact with the mating surface. The fingerstock is press fit into a non-metallic, non-conductive body with a molded-in insulation bushing. This ensures excellent electrical contact between the contact and the mating surface with no possibility of wear or corrosion. The non-metallic body further ensures a low stack height and high temperature and insulation for the contact assembly.

The gasket assembly used with the 4056PA51G00137 contact is designed to provide a secure, airtight seal between two mating surfaces. The gasket is constructed of high temperature silicone rubber with a self-adhesive double-sided tape for easy installation. It is then covered with an electrically conductive plastic layer for corrosion protection and to provide a seamless electrical connection. The gasket ensures that the contact surfaces have a low resistance path when mated together, ensuring a low electrical leakage and consistent signal quality.

In addition, the 4056PA51G00137 contact assembly is designed to meet or exceed a variety of requirements for RFI/EMI attenuation and conductivity. It meets MIL-STD-461F for conducted, radiated, and absorbed immunity requirements. The assembly is also certified to meet UL 94V-O flame retardancy class, confirming that it will not melt or turn to ash when exposed to high temperatures. The assembly is further certified to UL 1604 for safety and environmental standards, as well as RoHS and REACH for compatibility with a range of equipment.

The 4056PA51G00137 contact assembly provides reliable EMI/RFI prevention in a range of applications. It is suitable for a variety of purposes, from power supplies to connectors and cable assemblies. Its high temperature insulation and low stack height, combined with its extensive certifications, make it ideal for a wide range of uses in the commercial and military markets.
