Rectangular Connectors - Headers, Male Pins are commonly used in many applications. One such connector is the EJH-125-01-S-D-SM-30-K. This article will discuss the application and working principle of this particular connector.
Application of the EJH-125-01-S-D-SM-30-K
The EJH-125-01-S-D-SM-30-K, known also as a header, is a type of rectangular connector used widely in the manufacturing of electronic equipment. It is especially useful in applications requiring many multiple contacts along a single side. The connector measures 15.35mm in length and features a 6.22mm pitch for general low-profile applications. Due to its ability to plug into many printed circuit boards, as well as the fact its pins are of standard 0.5mm pin pitch, this header is ideal for use in almost any PCB design.
Most often, the EJH-125-01-S-D-SM-30-K is used in applications requiring low voltage and up to 30A maximum currents. Its short length makes it useful in PCBs using thick copper for better heat transfer. Additionally, this rectangular connector is perfect for use in boards with high-frequency signals as it offers a good impedance match.
Working Principle of the EJH-125-01-S-D-SM-30-K
The EJH-125-01-S-D-SM-30-K works using two electrically-conductive surfaces that are connected together. An array of spring-loaded gold-plated pins are located on one side of the connector and provide the electrical contact. The surface of the pins are designed to offer good contact and ensure a tight fit between themselves and the mating contact. As such, this ensures reliable high current connections while also protecting against potential electrical shorts.
Additionally, the EJH-125-01-S-D-SM-30-K also works with a locked tab that secures the male and female contacts in place. This feature is especially useful in applications where the electrical contact needs to remain secure. The locking tab ensures that the connector stays securely locked into place and prevents any accidental disconnections.
Conclusion
The EJH-125-01-S-D-SM-30-K rectangular connector is a versatile and reliable connector used in a wide range of applications. Its ability to handle high current and frequencies, combined with its easy to use locking tab make it ideal for almost any PCB design. As the connector is only 15.35mm in length, it is also useful for applications requiring low voltage and up to 30A maximum current. It is no wonder why it is a popular choice for many PCB manufactures.
