Introduction
The EJH-120-01-S-D-SM-LC-12-K is a quality header with male pins that is commonly used in construction of printed circuit boards (PCBs) and other electrical applications. It is typically used as an electrical connector to join two or more electrical components together. This type of header provides reliable current transfer between the components, whether through its soldered mount connector assembly or the direct connection of the device\'s pins.ApplicationField
The application field for the EJH-120-01-S-D-SM-LC-12-K is expansive. This header is most commonly used in automotive wiring and computer applications, but it can also be used in telecommunications, industrial machinery, medical equipment, and consumer electronics. This header is also an excellent choice for applications that require a reliable connection but are subject to vibration or temperature and humidity variations. This type of header is often used to reduce the assembly time for printed circuit boards, as it provides a secure and reliable connection between the components in a way that is both time- and cost-effective.WorkingPrinciple
The EJH-120-01-S-D-SM-LC-12-K header is designed to provide an easy and secure connection for two electrical components. The header is designed with male pins, which can be connected directly to the contact points of the components, allowing for a low-resistance connection between the two devices. This type of connector is also equipped with a soldered mount, allowing for a secure attachment to the board. The male pins on the header can also be soldered on both sides of the printed circuit board, creating a polarized contact between two components. This ensures that the components are always connected in the correct orientation, ensuring a reliable current flow and avoiding any possibility of short-circuits. The soldered mount also provides a secure and reliable connection between the device and the PCB, ensuring that the connection does not fail even under harsh conditions.Conclusion
The EJH-120-01-S-D-SM-LC-12-K is an excellent choice for electrical and electronic applications. It is a reliable and cost-effective way to join two electrical components together while also providing a secure connection between the components and the PCB. Its male pins can be soldered to either side of the printed circuit board, creating a polarized connection between the two devices and avoiding any possible short-circuits. The soldered mount also ensures a secure and reliable connection between the device and the board, providing even greater reliability for harsh environment applications.
