Rectangular Connectors - Headers, Male Pins

The EJH-125-01-S-D-SM-17-K is a standard rectangular connector component used as a header or a male pin in electrical systems. It is two contacts wide, with a thickness of 0.2 inches, and is manufactured with a PH 2.5 square head.

Applications

EJH-125-01-S-D-SM-17-K is used in a variety of electronic systems. Its most common use is as a connector in the Printed Circuit Board (PCB) assembly of consumer electronics such as computers, mobile phones, and televisions. It is also used in medical and military applications, as well as in industrial machinery.

Features and Benefits

The EJH-125-01-S-D-SM-17-K is a cost-effective component that is also reliable. It has a low contact resistance of 30 mΩ, low contact user of 0.5A@12V, and withstands up to 2000VAC pressure. It is also RoHS compliant, ensuring it is safe for use in electronic systems.

Working Principle

As with most rectangular connector components, the EJH-125-01-S-D-SM-17-K is made up of two parts - the header and the male pin. The two parts connect electrically when they are joined together. The male pin is inserted into the header with the contact spring inside. As the pin is inserted, the contact spring contacts the header\'s PCB pad, allowing the two parts to make an electrical connection.

Installation

The EJH-125-01-S-D-SM-17-K is installed by first removing the adhesive tape from the contact spring. The pin is then inserted into the header and the adhesive tape is replaced. The pin should be pressed firmly into the header so that the contact spring is securely in place and making contact with the PCB pad. Finally, a solder joint should be made at the contact points to ensure a high-quality connection.

Conclusion

The EJH-125-01-S-D-SM-17-K is a standard rectangular connector component used as a header or a male pin in many electronic systems, making it suitable for a wide variety of applications. With its low contact resistance, low contact user, and high withstand voltage, the EJH-125-01-S-D-SM-17-K is a reliable component that offers cost-efficiency. It is also easy to install as long as a solder joint is made at the contact points.
