Modular connectors, such as jacks with magnetics, are a ubiquitous electrical component used to transmit a variety of electrical signals, from simple DC current or voice and data signals to more complex signals in industrial applications. This article will discuss the ARJM11B1-805-AB-EW2 – a jack with magnetics – and its application fields and working principle.

Introduction

The ARJM11B1-805-AB-EW2 is a modular connector that follows industry standards, such as TIA/EIA-568-B-2, IEC 61156-5 and M12-A. This component is designed for data transmission and other related applications, and it is particularly popular for connecting Ethernet networks. As its name implies, it is a jack with magnetics, which combines the traditional handling of modular connections with the advantages of magnetics.

Application Fields

This magnetic jack is most commonly used in Ethernet applications, including 10GB/s Base-T or Base-X applications. It is also useful in industrial applications, such as factory automation, process control, and machine building. Lastly, it is commonly used in automotive networking and environmental monitoring, as these applications require reliable data transmission.

Working Principle

The ARJM11B1-805-AB-EW2 uses three parts to facilitate transmission. It consists of a shielded RJ-45 plug, a UL-approved magnetics module, and a dielectric insulating ring. The magnetics module contains two inductors, which block noise interference and provide reliable transmission of signal. It also provides a 120Ω differential impedance, which helps reduce the amount of reflected signals and crosstalk.

The magnetic module also provides isolation of the transmission signal from the environmental noise. It does this by containing three bobbin-wound coils – one for the Tcn signal, one for Tc- continuity, and one for the Tcd signal. When current passes through these coils, it creates a magnetic field that shields the signals from environmental interference. This shielding helps ensure reliable data transmission.

The dielectric insulator ring provides additional electrical protection. It prevents signal leakage between conductor pairs. This insulation is important, as it helps prevent accidental short circuits or voltage spikes caused by conductor-to-conductor leakage.

Conclusion

The ARJM11B1-805-AB-EW2 is a popular modular jack with magnetics that is used in a variety of applications, such as Ethernet, automation, and environmental monitoring. Its combination of shielded RJ-45 plug, UL approved magnetics module, and dielectric insulating ring helps ensure reliable transmission of electrical signals. This combination of components makes the ARJM11B1-805-AB-EW2 a great choice for data transmission and other related applications.
