Modular connectors are developed to allow versatility and flexibility within an electronic system design. ARJM11C7-116-AB-CW4 is a type of modular jack connector equipped with magnetics that can be used in many applications. In this article, we will discuss the application field and working principle of the ARJM11C7-116-AB-CW4.

Application Field

The ARJM11C7-116-AB-CW4 is mainly used in the telecommunications industry, more specifically in Integrated Access Devices (IADs) and Voice over Internet Protocol (VoIP) platforms. It can also be used in connection equipment such as Digital Subscriber Line (DSL) modems and gateways. It is suitable for Ethernet applications where it can be used to connect the copper wire of the communication line directly to interface cards or printed circuit boards.

This jack connector also has audio applications as the integrated audio transformer can reduce externally induced noise in a digital signal allowing for higher signal fidelity. In addition, it is the perfect choice for emerging USB type-C applications making it ideal for high bandwidth applications. Its compact and light-weight design also makes it suitable for applications that are size and weight restricted.

Working Principle

The ARJM11C7-116-AB-CW4 comprises two main parts, the modular jack itself and the magnetics module. The jack is designed to accept both Shielded (STP) and Unshielded Twisted Pair (UTP) cables as well as Solid and Stranded cables. The contact of the jack has four positions that connect the wires to the respective pins of the panel when a plug is inserted. As for the magnetics module, a 105°C temperature rated insulator with low profile dimensions form the base for the shield and magnetics package. It combines a line side transformer together with both common mode and differential mode line side inductors.

In operation, when a plug is inserted into the modular jack, the contact of the jack complete a connection between the plug housing and ground, which establishes the EMI shielding. At the same time, the signal and power are also transmitted smoothly and reliably. The magnetics module reduces EMI, protect the signal and also filters out power line disturbances which ensures signal integrity on both sides.

Conclusion

From the above discussion, it is clear that the ARJM11C7-116-AB-CW4 jack connector is a versatile and reliable solution for many applications such as telecommunications, Ethernet and audio. It provides outstanding EMI-shielding and also filters out power line disturbances to ensure signal integrity. It is perfect for emerging USB type-C applications as well as size and weight restricted applications. It is a great choice if you are in need of a robust modular jack connector with magnetics.
