RFI and EMI - Contacts, Fingerstock and Gaskets have a variety of applications ranging from shielding and grounding, to Isolation via capacitance, to sealants against dust or moisture and using them in conjunction with contact materials achieve an array of electrical and mechanical goals.

One popular example of this type of contact material is the 4078PA51G01800. It is an extruded nickel plated steel fingerstock with a silver bearing nickel plating. This combination of materials helps offers superior corrosion and electrical resistance making it a great choice for applications where RFI and EMI interference must be addressed. The metal structure and the plating also provide a solid mechanical bond when used for contact applications.

Initially, this fingerstock comes in the form of a reel or coil. Its characteristics allow it to be cut into different sizes depending of the application. This fingerstock is especially suited for applications that require low contact resistance and reliably high contact integrity. The material’s silver-bearing nickle plating also minimizes the risk of oxidation, even under demanding contact conditions.

The 4078PA51G01800 can be used in a variety of applications from optics and electronics shielding, to connectors, switches and relays, to mechanical mounting and closure. This is due to its ability to form a secure contact in various environments.

It is in these kinds of applications that the fingerstock is cut to length and configured with a groove for snap-in fastening in the most common use. The length and shape, as well as the shape of the groove can all be customized to meet the specific requirements of each individual application. Also, the fingerstock can be fashioned into various contact pads, such as circles, rectangles, or complex shapes for board-level applications.

The working principle of 4078PA51G01800 application is based on its characteristics and it works due to the combination of electrical and mechanical contacts. It functions as a meachanical interface with a contact surface area that must exceed the surface area of the contact finger. This allows the finger to contact the substrate while providing a low-resistance path that will be used to complete the electrical circuit.

In order to offer reliable mechanical contacts, it is often combined with other materials like elastomers, thermoplastics and abrasive compounds in order to enhance its performance while providing insulation, dampening, strain relief or compression. The material is also often used in conjunction with other contact materials such as carbon, gold, or noble metals.

To conclude, contacting materials such as 4078PA51G01800, contacts, fingerstock, and gaskets are essential materials in a variety of applications. They offer reliable conductivity and electrical insulation while still being versatile enough to serve in many applications. Their ability to form a mechanical contact also makes them reliable as an electrical interface. The combination of electrical and mechanical contacts makes them a reliable choice that enables them to be used in shielding, cable termination, snappable mounting, or switch and relay operations.
