EHT-122-01-S-D-SM-LC-15-K Application Field and Working Principle

Introduction to Rectangular Connectors - Headers, Male Pins

Rectangular connectors - headers and male pins are commonly used in connecting cables and computerized devices. Rectangular connectors and male pins use the same physical connection of a board-to-cable design, but offer unique benefits that make them an important part of any electronic connection. Male pins are designed to provide a reliable and secure connection in a variety of environments, ranging from high-speed data connection to industrial and automotive applications. Male pins also offer a safe and reliable means of protecting sensitive components from harm.

EHT-122-01-S-D-SM-LC-15-K Application Field

EHT-122-01-S-D-SM-LC-15-K is a type of rectangular connector - header with male pins, designed to provide a reliable and secure connection in a variety of application fields. This connector is suitable for connecting cable and boards, for instance, in the areas of computer test and measurement, electrical and automotive, industrial automation, telecommunications, and medical. As the part of interconnection and trans-cable solution, EHT-122-01-S-D-SM-LC-15-K can be used in the data transmission scenarios of 1 Gbps and 2.5 Gbps. Moreover, due to its excellent performance in electrical & mechanical contract, the speed of the connection can be raised up to 3.2 Gbps.

Specification

The EHT-122-01-S-D-SM-LC-15-K is a type 2.54mm double row SMD pitch connector with 6mm width. Its size allows its mounting on small, medium and large boards, making it fit for almost every board design out there. The metal shielding allows is to effectively reduce the signal interference, guaranteeing the reliable long-term transmission. The stainless steel finish gives the connector an additional layer of protection against environmental elements, such as humidity and dust, making it ideal for outdoor applications.

Working Principle

The EHT-122-01-S-D-SM-LC-15-K connector uses contact pins for secure electrical contact between two objects, forming an electromechanical interface. This interface includes two contact pins on one side of the connector, and two matching contact pins on the other side. These two sides form an electrical switch that will close or open when the two sides are connected. The connection is then sustained by the contact resistance between the two contact pins on each side. In addition, a spring-loaded power pin is included as additional protection against accidental disconnection of the connector, providing a mechanical type of contact retention.

Conclusion

EHT-122-01-S-D-SM-LC-15-K is a type of rectangular connector with male pins, designed to provide a reliable and secure connection in a variety of application fields. The EHT-122-01-S-D-SM-LC-15-K works in two way: firstly, it uses contact pins for an electromechanical interface, and then its spring-loaded power pin provides a mechanical type of contact retention. The size of the EHT-122-01-S-D-SM-LC-15-K allows it to be suited for almost any board design and its metal shielding helps to reduce signal interference. Therefore, the EHT-122-01-S-D-SM-LC-15-K is a great choice for connecting cables and boards quickly, safely and reliably.
