Introduction
EJH-122-02-L-D-TH rectangular connectors are a type of electrical connectors that are designed to join – or connect – two circuits or components. These headers and male pins are two elemental parts of the rectangular connector family which operates on the same principles as a typical connector, that is to create a safe and reliable connection between two components. Rectangular connectors are often employed in interconnection between PCBs, modules, sensors, actuators and other electronic components.
Applications
EJH-122-02-L-D-TH rectangular connectors are primarily used in the engineering and electronics industry, including its application in automotives, medical, industrial, instrumentation and communications technologies. Moreover, the abrasion of these polarized, two-piece headers and male pins also make them suitable for wiring harnesses or connecting PCBs and other components in automated machinery, robotics and other related applications.
Construction & Materials
EJH-122-02-L-D-TH rectangular connectors are constructed using high-quality, sturdy materials that are designed to last. These headers and male pins come in a rectangular shape and they are made of corrosion-resistant materials such as brass, copper, aluminium and thermoplastics. The pins typically have two or more contact points to ensure a secure connection to two or more components or boards. The contact points usually consist of a pin, socket, blade or lug which has been machined or moulded from the material used. Furthermore, the contact points are often plated with gold, tin-plated or nickel plated for further protection from corrosion and oxidization.
Working Principle
The functioning of EJH-122-02-L-D-TH rectangular connectors relies on the principles of conducting electricity. Like other types of electrical connectors, the rectangular shape of these components aids in creating a secure connection – thanks to their generally higher contact area than round or square connectors. The headers and male pins of the EJH-122-02-L-D-TH connectors work together to connect two separate circuits and components. This helps to prevent the loss of current. The male pins have two contact points at each end, which are used to make contact with the female counterparts which are mounted on the PCBs or components. This creates an electrical connection which allows current to flow between the connected components.
Key Features & Benefits
EJH-122-02-L-D-TH rectangular connectors offer a number of key features and benefits that make them a suitable option for several applications. They have a wide temperature range from -55°C to 125°C, which makes them ideal for use in industrial and automotive environments. Moreover, they are highly durable and of superior quality, making them extremely reliable connectors. Furthermore, the design of these headers and male pins allows them to be easily installed and removed which makes them convenient to use. Additionally, they are also RoHS compliant, providing environmental protection. Finally, they are designed to provide superior protection from dust, moisture, and physical damage, ensuring robust and secure connection of two components.
Conclusion
The EJH-122-02-L-D-TH rectangular connectors are high-quality, reliable and durable electrical connectors used in the engineering and electronics industry. Their rectangular shape offers superior contact area when compared to round or square shapes. They come with two-piece headers and male pins that work together to connect two circuits or components securely. Furthermore, they are RoHS compliant, highly durable and can withstand temperatures ranging from -55°C to 125°C. As a result, EJH-122-02-L-D-TH rectangular connectors offer a suitable choice for various applications, including in automotives, medical, industrial, instrumentation and communications technologies.
