MS3420-8 Application Field and Working Principle

The MS3420-8, part of a range of circular connectors and accessories, is a shear-head crimp connector which is used to join two cables together. It is designed to easily and consistently provide the secure connection required in a variety of harsh environments from military and aviation to ground control and communications.

The MS3420-8 can be used to join any two cables with cross sectional diameters of 20-28 AWG. The connector is designed to function in temperatures ranging from -55°C to 150°C, enabling it to be used in extreme situations. The gold plated contacts ensure that corrosion and oxidation are minimised over time, making the MS3420-8 reliable and durable for many years.

The MS3420-8 consists of a contact system containing an integrated compression nut and shear-head nut, with a body that prevents slippage during the termination process. The connector is also equipped with an annular ring which is used to rotatably prevent the accidental loss of the contact during rotor installation. The contact system features a satin stainless steel finish, designed to resist corrosion and wear.

The working principle of the MS3420-8 is straightforward. After the cables are cut to the required lengths, the ends of the cables are stripped and the wire strands are tinned. The contact system is then inserted into the body of the connector. The external cable is then stripped and the strands are tinned. The external nut is then tightened, which clamps the internal and external cables together. Finally, the external shear head nut is tightened, which cuts the strand of wire, thus making a secure connection.

The MS3420-8 is designed to be used in a variety of applications, such as aerospace, ground control, broadcast, communications, industrial, automotive, and marine. It is commonly used in systems requiring reliable and durable connections in extreme environments, and is suitable for rugged military and outdoor applications. The MS3420-8 is easy to install and provides a consistent and secure connection, ensuring that the system will remain reliable and successful for years to come.
