RFI and EMI - Contacts, Fingerstock and Gaskets

The 4210AB51K00180 contact, fingerstock, and gasket combines electron beam physical vapor deposition (EB-PVD) chrome coating with gold plating technology to produce a high-performance contact product for electromagnetic interference (EMI) and radio frequency interference (RFI) shielding applications. It is used primarily in the automotive, aerospace, industrial and medical industries.

Application Field

The 4210AB51K00180 contact, fingerstock, and gasket system offers superior EMI/RFI shielding when used with semi-rigid or flexible cables for shielding applications. It is especially well suited for applications involving harsh environments and frequent contact, such as motor vehicle engine compartments, aircraft cabin interiors, and industrial equipment. The contact fingerstock is also designed for use in high-voltage applications. It is designed to meet military specifications (MIL-S-8802) for EMI/RFI shielding effectiveness and construction.

Working Principle

The contacts and fingerstock are made using an EB-PVD chrome coating with gold plating and are offered in three standard sizes: 2mm, 3mm, and 4mm. The contacts feature a self-cleaning design that continually wipes away any build-up of dirt or debris, providing a better electrical connection overall. The fingerstock is designed with one or two rows of contacts, depending on the size of the application. This design improves the electrostatic performance and EMI/RFI shielding effectiveness of the contact system.

The gasket is designed for use in harsher environments. It is constructed using a conductive rubber magnetic material with chrome coating and gold plating treatment to provide corrosion resistance and EMI/RFI shielding. The gasket’s unique design enhances the contact system’s flexibility and allows for a better fit in most configurations.

The 4210AB51K00180 contact fingerstock and gasket system is designed to meet stringent EMI/RFI shielding performance requirements, ensuring the highest quality connection for any application. In addition, its chrome coating and gold plating provide excellent corrosion and abrasion resistance, making it suitable for long-term use in harsh environments.
