RFI and EMI - Contacts, Fingerstock and Gaskets – the 4084PA51H01200 application field and working principle.

RFI (Radio Frequency Interference) and EMI (Electromagnetic Interference) shielding products provide ESD (Electrostatic Discharge) protection and ensure safe electromagnetic radiation levels. We are now going to look at one particular product – 4084PA51H01200 – and discuss its application field and working principle.

The 4084PA51H01200 belongs to the range of RF/EMI contact fingers, fingerstock and basic gaskets. It is an electro-mechanically fastened contact finger designed for use in RF/EMI shielding applications. The product is made using high performance conductive elastomers and metal-plated steel cores, with the primary purpose of providing grounding path from ELab or control panel ESD point to shielding components in compliance with EMI filtering specifications.

The 4084PA51H01200 offers a simple installation and is suitable for commercial, industrial and military applications such as computer housings, connectors, ELab cabinets, ECUs, PDUs, safety enclosures and ground busses. It has been tested according to the ANSI/ESD S20-20 standard and offers a 50-1000 megahertz frequency range, as well as a voltage rating of 200V and a resistance range of 0-10 Ohms.

The working principle of the 4084PA51H01200 is to establish a conductive path between the ELab or control panel and the component frame or EMI filter in order to maintain proper EMI/RFI shielding. The product consists of two parts: the metal-plated steel core and the conductive elastomer insulator. The steel core provides a stable path of conduction, while the elastomer insulator reduces electrical capacitance losses.

In order to ensure a proper connection, contact should always be secured with the hex nut provided, and a Loctite adhesive (Grade B) should be applied at the assembly stages and at intervals of thirty days. An appropriate contact grease (for example, Krytox 243 or equivalent) should also be used for lubrication and reducing mating forces.

In addition, we must not forget that the 4084PA51H01200 should also be installed in EMI / RFI shielding enclosure (as specified by the manufacturer) to ensure theoretical and mechanical shielding. Contacts should always be provided with a robust mechanical connection to the application-specific frame. Proper contact pressure should be ensured by means of special tools.

Finally, it is important to follow the manufacturer’s instructions for installation and any other applicable requirements, such as field service safety guidelines. All components should be installed and maintained according to the manufacturer’s instructions.

The 4084PA51H01200 provides a solid grounding connection and EMI / RFI shielding performance in a range of commercial and industrial applications. Its simple installation and robust construction make it a reliable, long-term solution for shielding applications.
