EJH-120-01-S-D-SM-LC-31-P Connectors are an integral part of any electronic system. These are generally referred to as “headers” and consist of a plastic body with metal pins extending from it. Within the category of rectangular connectors, this specific type of connector is classified as a header, male pin connector.The connector body is typically made from a polyethylene terephthalate, or PET, material. This provides the device with the necessary physical and electrical properties. Within the plastic body is a set of electrical contacts. These contacts are metallic pins that are wired according to the electrical requirements of the system. This is done using a solderless crimp connection technique.The purpose of this type of connector is to provide a means for the system to communicate with other external components. Examples of these components include wireless modules, wired circuits, air-interface devices, etc. The header, male pin connector is used to connect two external components together, allowing data and electrical signals to flow between them in a safe, secure, and reliable manner.The working principle of EJH-120-01-S-D-SM-LC-31-P is based on the concept of impedance matching. Impedance matching involves tuning electrical signals for optimal transfer between electronic components. Using the principles of Faraday\'s Law, the design of the header, male pin connector allows for two components to be connected in a low-impedance environment. This ensures that any signals flowing between the two components can do so efficiently, without any signal loss or interference.The application fields of EJH-120-01-S-D-SM-LC-31-P Connectors are vast and include automotive, military, medical, industrial, etc. These connectors are most commonly used in industrial control systems, securing automated assembly line machinery, and other high-speed data and communication systems. Additionally, they can be used to connect robotic systems, electronic test and measurement equipment, and various types of sensors.In conclusion, EJH-120-01-S-D-SM-LC-31-P Connectors are rectangular connectors classified as headers, male pins. They are used to provide a means for two external components to communicate with each other and incorporate the principles of impedance matching to ensure efficient signal transfer. These connectors are widely used across various industries and applications, providing a reliable and secure connection between two components.
