EJH-110-01-FM-D-SM application field and working principle

Rectangular Connectors - Headers, Male Pins, are commonly used in a range of electrical applications. The EJH Series from TE Connectivity is one such range, and the EJH-110-01-FM-D-SM specifically is one of the male pins from this range. Its usage is in a broad range of applications including telecommunications, consumer electronics, medical equipment, industrial automation, and aerospace applications. This article will discuss in detail the application specificities and the working principles of the EJH-110-01-FM-D-SM connector.

Application

The EJH-110-01-FM-D-SM connectors are an 8 pin header, commonly used in telecommunications, consumer electronics, medical equipment, industrial automation, and aerospace applications. Due to the wide range of applications it is used in, the connectors are versatile and help in inter-connectivity between different boards, ensuring proper functioning of the equipment connected. The connectors are classified into four categories: high voltage (for higher voltages), shielded (for enhanced signal integrity), through-hole (for enhanced structural integrity), and low profile (for reduced overall board thickness). The design of the EJH-110-01-FM-D-SM connectors make them extremely reliable and offer a robust and secure connection. The connector has a number of features which account for its reliability such as an anti-snag latch, recessed walls for solder anti-swell protection, and a PCB mountable latch. The connectors are currently available from TE Connectivity with a choice of gold, tin, and carbon-zinc plating. The gold plating offers improved electrical and thermal properties, while the tin plating provides resistance to corrosion as well as protection against soldering. The carbon-zinc plating helps to improve the conductivity and thermal properties of the connector while being cost effective.

Working principle

The EJH-110-01-FM-D-SM connectors are designed to provide a reliable and secure connection. This is achieved by creating an electrical connection between the pins and the contacts. The electrical connection is then secured by invoking a physical lock mechanism. The pins are designed to ensure good electrical contact with the contacts. This is achieved by the use of tin/gold plating which increases the surface area available for contact. This ensures good electrical conduction and hence a reliable connection. The physical lock mechanism is designed to ensure that the electrical connection remains secure. This is done by having an anti-snag latch which helps to lock the electrical connection and prevent it from becoming loose. The latch also helps to prevent any external vibrations from disturbing the connection. In addition to the latch, there are also recessed walls in the connector which ensure that there is sufficient solder protection from the board. This ensures that the electrical connection is not prone to any solder damage and will power the attached device for a long time. Finally, the PCB mountable latch helps to ensure that the connector stays in place on the PCB. This ensures that the electrical connection is secure and not prone to external vibrations, which can cause the connector to become loose or damaged.

Conclusion

The EJH-110-01-FM-D-SM connector is a reliable and secure rectangular connector from the EJH Series from TE Connectivity. It is available in a range of plating types, and can be used in a broad range of applications including telecommunications, consumer electronics, medical equipment, industrial automation, and aerospace applications. Its design helps to ensure the reliability and secure connection of the device, with features such as an anti-snag latch, recessed walls for solder anti-swell protection, and a PCB mountable latch.
