SS-39200-021 Connectors, Interconnects

Modular connectors have been used in the IT industry for decades as a highly reliable interface between computing devices and peripheral components. The SS-39200-021 plug, a modular connector used in the telecommunications sector, is one of the most widely employed units in this field. This article will discuss the application field of the SS-39200-021 plug and its working principle.

Application field of the SS-39200-021 plug

The SS-39200-021 plug is a four-conductor plug specialised for applications in the telecommunications and data communications sectors, mainly for voice and data transmission. It is primarily used for connecting telephones and modems to digital subscriber lines and other data communication systems. Additionally, the plug is versatile enough to be used to terminate other connections in fibre optic, LAN, and other network cables, including outdoor connections such as junction boxes for fibre optic cables.

Working principle of the SS-39200-021 plug

The SS-39200-021 plug operates by forming a physical contact between the pins of the plug and the corresponding pins in the mating socket. It is composed of four metal contacts that are arranged in a rectangular pattern. The contacts have a rounded shape in order to comply with standards for telecommunications plugs, and each contact is approximately 1.35 mm in diameter. The contacts are coated with stainless steel to provide improved conductivity, corrosion resistance, and protection against dust and dirt.

The SS-39200-021 plug is designed to allow for secure locking between the plug and its mating socket when inserted. This is accomplished by the use of spring-loaded pins in the contacts, which push the upper elements of the plug upward upon insertion. This creates a mechanical interlock between the two components that prevents accidental disconnection due to vibration or shock. Additionally, the plug is designed in such a way that it is protected from water and dust ingress, thereby further increasing its reliability and dependability.

Conclusion

The SS-39200-021 plug is a versatile and reliable modular connector that is widely used in the telecommunications sector for connecting telephones, modems, fibre optic cables, and other network equipment. The plug is designed to form a physical contact between its pins and those of its mating socket, with the help of spring-loaded pins. This ensures a secure and reliable connection that is further protected against water and dust ingress.
