Rectangular cable assemblies provide a reliable solution for cable management challenges. They are widely used in applications such as aviation, aerospace, and automotive industries. M3URK-4018J is one of the most popular rectangular cable assemblies in the market. This article focuses on M3URK-4018J application field and working principle. ApplicationsM3URK-4018J has a wide range of application fields. It is often used as a connector for sensors, actuators, and other electronic components in industrial automation, process control, and telecommunication systems. It is also suitable for harsh environment applications, such as in off-road vehicles, mining, agriculture, aviation, wind power, and robotics. Moreover, it can be used as a connection for solar energy system, as well as for medium and low voltage electrical power systems. Working PrincipleThe M3URK-4018J is composed of two solid plastic housings with contact connectors. The housings have two metal shells, which provide the necessary protection against dirt, dust, moisture and corrosion. The metal shells are then filled with thermoplastic elastomer, which acts as a sealant to protect against moisture and dust. The two shells are also connected with a reliable soldered joint, which provides an optimal mechanical and thermal connection. The soldered joint is also insulated with a special insulating material, which ensures an optimal electrical connection.Inside each of the housings is a shielded contact. The contact is made up of two components: the contact pin and the contact finger. The contact pin is insulated with a rubber seal and secured with a steel strain relief. Meanwhile, the contact finger is made of stainless steel and is pre-tinned. The contact pin is inserted into the contact finger, and the assembly is then secured in place with a stainless steel clip. The M3URK-4018J is designed with a center tap, which reduces the resistance and provides better current carrying capacity. The contact also has an outer diameter cover, which is insulated with a non-conductive material and is designed to provide effective protection from vibration and electrical corrosion.ConclusionM3URK-4018J is a popular rectangular cable assembly which has become increasingly popular in a wide range of industries. It is composed of two solid plastic housings with contact connectors, a shielded contact, and a center tap, which provide an optimal electrical connection while protecting the electrical components from dust and moisture. It is suitable for use in a wide range of applications, such as in industrial automation, process control, and telecommunication systems, as well as in harsh environments, such as in mining, wind power, and robotics.
