The 4105PA51G01800 is a specified contact, fingerstock, and gasket that is designed to limit the unwanted transmission of both radio frequency interference (RFI) and electromagnetic interference (EMI). In practice, this contact is used to prevent EMI from escaping an electronic device or instrument, as well as to block out interfering frequencies from entering the device. The contact is usually employed when connecting cables to the rear of a device, or wires to a chassis, allowing electrical signals to pass through while filtering out any extraneous noise. Additionally, use of the contact is beneficial for reducing the overall size of the device.

In terms of construction, the 4105PA51G01800 contact consists of a molded cable enclosure and a terminal block. The cable enclosure is made up of two layers of thermoplastic material, one of which is conductive to ensure effective shielding. The terminal blocks are made from aluminum, coated with nickel-plated steel, and are designed to offer reliable, low-loss connections between cables or wires. The connection between the two layers of the enclosure and the terminal blocks is made using interlocking fingers, providing an interface that is resistant to external vibrations.

When in operation, the contact reduces the escape of RFI and EMI by providing an impenetrable shield of low impedance copper, which is designed to absorb frequencies from 9kHz to 3GHz. Additionally, the enclosure is designed to reduce the susceptibility of EMI entering or leaving a device. This is achieved through a combination of shielding, grounding, and the inclusion of a wire-to-wire connection where appropriate.

The 4105PA51G01800 contact is commonly used in a variety of industrial applications, including portable computing and communications devices, networking equipment, and testing modules. In terms of cost, the contact offers an affordable solution for minimizing interference in electronic devices, as well as reducing the overall impact of RFI and EMI on their operation. In addition to its use in industry, the contact is also of great benefit in residential applications, where its ability to reduce noise and improve signal integrity make it a highly desirable item.

Overall, the 4105PA51G01800 contact is a highly effective solution for reducing the risks associated with RFI and EMI, while also allowing for smaller designs. The contact is designed to provide maximum shielding effectiveness, while still offering the highest quality connections. In addition, its use in a range of industrial and residential applications helps to ensure that its use is ubiquitous. The contact offers users a cost-effective way to maximize the performance of their electronic devices, and to minimize the amount of interference that they experience.
