Working principle

4693AB51H01800 Contact Fingerstock Gasket is made up of three parts—emulsion glue, alloy coil and contact fingerstock—which is composed of a mat material of metallic wires, such as steel, tin plated steel, tin-nickel, and so on, with two wires intersecting each other and forming an entire spring-like structure. This gasket is capable of conformally fitting various surface and hole sizes, and provides shielding efficiency of up to 120dB at frequencies ranging from 0.1 to 20 GHz. The working principle of 4693AB51H01800 Contact Fingerstock Gasket is basically that, the emulsion glue enables the gasket to conformally fit various surface features, while the contact fingerstock and alloy coil form an infinitely thin double conductive layer, which can greatly reduce the interference of radiation signals, provide superior EMC performance and ensure reliable connectivity of products.

In conclusion, 4693AB51H01800 Contact Fingerstock Gasket is a kind of product specially designed for radio-frequency interference (RFI) and electromagnetic interference (EMI) shielding with wide application field and reliable working principle. It can be used in wide variety of applications, such as electronics and electrical products, computer modules, aircraft fire extinguishing systems, aircraft lighting systems, etc., contributing to reduce the interference of radiation signals and ensure reliable connectivity of products.
