Rectangular Connectors – Headers, Male Pins offer reliable interconnections for applications in various markets such as consumer electronics, telecommunications, industrial and automotive. Model 78208-209 is a 24-pin header connector with a maximum current rating of 12A, designed for up to 2.5mm PCB thickness, and features integral lock for secure termination and excellent mating retention. This article explains the application field, working principle and advantages/disadvantage of this connector.

Application Field

The 78208-209 model is widely used in consumer electronics and telecommunications applications. This connector has a 24 pin header style, with a high-current rating of 12A, and is designed to fit on PCBs with a thickness of 2.5mm. It has a latch to provide secure mating and retention, and also features a self-grounding capability to ensure reliable signal integrity. In addition, this connector is ideal for applications that require high reliability, such as solar panel installations, LED lighting projects, and other applications that require reliable power and signal transmissions.

Working Principle

The 78208-209 connector uses a standard male and female header contact system for signal transmission. A latch design provides a secure, reliable mating connection. The pins on the male connector insert into the pin holes in the female connector and are held in place by the latch. There is an inner sleeve that allows for adjustments to the position of the pins, which improves the connection and aids in signal integrity. The connector uses gold plated contacts that allow for a reliable connection with low contact resistance.

The connector features a self-grounding system, which eliminates the need for external grounding connections. This feature helps to ensure a consistent ground and prevents crosstalk and interference. The galvanized shield helps to protect the signal integrity.

Advantages/Disadvantages

The 78208-209 connector has several advantages that make it a desirable option for many applications. The latch design ensures secure mating and reliable connections. The self-grounding system eliminates the need for external connections, and helps protect signal integrity. The gold plated contacts have low contact resistance and provide reliable signal transmission. Additionally, the connector is a quick and convenient method for making reliable connections with minimal effort.

Some of the drawbacks of the 78208-209 connector include its size and power rating. This is a relatively large connector and is rated for only 12A, which makes it inadequate for applications requiring higher power. Furthermore, the connector lacks a locking mechanism, which can lead to accidental disconnections in applications that require secure connections.

Conclusion

The 78208-209 model is a 24-pin header connector designed for use in consumer electronics, industrial and automotive applications. It provides reliable mating connections with low contact resistance and features a self-grounding system to eliminate the need for external ground connections. The connector has a maximum current rating of 12A and is ideal for applications which require reliable signal transmission and power. The 78208-209 model is a quick and convenient option for making reliable connections, with the caveats that it is large and cannot support the higher power levels required for some applications.
