RFI and EMI - Contacts, Fingerstock and Gaskets form the main components of a range of shielding products designed to protect electronic devices from electromagnetic interference (EMI). The 8868-0081-72 is one such product. It is an EMI contact fingerstock that combines conductive and insulating layers into a single product for maximum protection where space is a critical factor.

The 8868-0081-72 is designed for use in applications such as electrical panels, power supplies, communications equipment, and medical electronics. It offers protection from both radio-frequency interference (RFI) and EMI, which is necessary for the safe and efficient functioning of these critical systems. The product uses a bifurcated stretch design that allows it to be easily installed in tight spaces.

The working principle of the 8868-0081-72 is based on the well-known Faraday cage effect. This effect helps protect the internal components of a device from shocks due to induced electric fields. The contact fingerstock works by establishing an electrical connection between the metal shielding layer and the chassis of the device. This connection short-circuits any induced electric fields, thereby dissipating them as heat.

The 8868-0081-72 also features a conductive layer that provides electromagnetic shielding across a broad range of frequencies, including those of the radio-frequency spectrum. The conductive layer is formed from a layer of nickel plated steel, which is laminated onto the insulation layer. This layer helps ensure that all external EMF frequencies are contained within the device.

The 8868-0081-72\'s insulating layer helps increase its durability, as it prevents moisture from entering the device. The layer is made from silicone rubber and is resistant to wear, tear, and abrasion. The rubber also provides excellent electrical insulation, which is essential in protecting the device from any external electric shocks.

The product is also designed to be efficient with regards to energy consumption. It achieves this by having a contact resistance of < 0.2 milliohms, which is much lower than many other similar products. This low resistance helps reduce energy losses and consequently, lowers the overall power consumption of the device.

The 8868-0081-72 is an effective and reliable product for protecting sensitive electronic devices from RFI and EMI. Its Faraday cage effect helps protect the internal components of the device from electric shocks due to induced electric fields, while its conductive layer provides excellent shielding protection from external EMF frequencies. In addition, the product\'s low contact resistance helps reduce energy losses, ensuring maximum efficiency. As such, it is an ideal choice for any application where the protection of sensitive electronics is essential.
