Rectangular connectors are one of the key components in a variety of industrial systems. Among them, the SSM-109-SM-DH is a common type of connector due to its robust and reliable performance. This article discusses its application fields and working principle.

Application Field of SSM-109-SM-DH Connector

The SSM-109-SM-DH connector appears in a variety of applications. It is ideal for use in data processing and telecommunication systems, such as office automation, electric control, medical equipment, and automated manufacturing systems. As it is able to withstand high temperature and intense vibration, it is also highly suitable for use in the automobile and aerospace industry, notably in navigation and aviation systems.

It also works well in motors and robotics, especially those that require a secure connection. This connector is useful in PC cards, disk drives, and other power and control circuit connections. To ensure maximum performance and safety, it has passed the rigorous UL 94-V0 tests in terms of flammability and continuous Hi-Pot tests in terms of safety.

Working Principle of SSM-109-SM-DH Connector

The SSM-109-SM-DH connector has two mating halves, consisting of a header and a receptacle. It is a two-part, or “PCB-to-PCB”, connector type. The unique design of the SSM-109-SM-DH connector allows it to safely lock into place and reduce crosstalk and EMI noise. Additionally, it provides increased mechanical strength as well, due to its channelized structure.

The SSM-109-SM-DH utilizes a peg-and-cup design, meaning that a single female socket (or receptacle) is mounted on one printed circuit board or peripheral device, while the other is mounted on a mating male header (or plug). When fitting a plug into a receptacle, two spring-loaded pins (or “pegs”) located on the plug compress in the receptacle, which contains cups to receive the pegs. The pegs then press onto the inner walls of the cup, creating a secure connection which absorbs most of the forces imparted to the plug. This ensures a secure connection; one that will not become loose easily.

The SSM-109-SM-DH connector also has two ground pins (or “shields”) connected to the plastic body. This ensures that no EMI interference occurs between the two devices. The unique design of the SSM-109-SM-DH also allows for a higher resistance to shock and vibration than other types of connectors. Furthermore, this type of connector is also suitable for applications that are exposed to dust, dirt, and moist conditions.

Conclusion

The SSM-109-SM-DH connector is one of the most versatile rectangular connectors available. It offers robust and reliable performance and is an ideal choice for a variety of applications. It combines a secure connection with excellent electrical noise protection and high levels of vibration and shock resistance. This makes it an ideal choice for applications in the automotive, aerospace, medical, data processing, telecommunication, and industrial settings.
