Modular Connectors, or more specifically, jacks with magnetics, are devices used to couple electronics with magnetic properties in electronic cards. ARJM11B1-809-JA-ER2-T is a very popular one, which finds its use in many applications, especially in communication and networking. This article aims to present the application field and general working principle of this special jack.

Application Field

ARJM11B1-809-JA-ER2-T is a jack with magnetic suitable for IEEE802.3af compliant PoE applications. It provides power and data communication over a single Ethernet cable, which makes it extremely efficient and useful for application in networks. It can operate with maximum power up to 15W and data at a maximum rate of 10/100Mbps. This jack can also be used in many other applications due to its feature of maximum energy efficiency at low power consumption.

Moreover, ARJM11B1-809-JA-ER2-T is widely used in many other demanding applications such as PoE power backup, DC/DC converters, lighting control, security systems, CCTV and remote terminals. Its special features such as EMI/RFI shielding and noise reduction capability makes it a good choice for these kinds of applications.

Working Principle

The ARJM11B1-809-JA-ER2-T works on the principle of inductive coupling. This means that it transfers energy using the electromagnetic induction principle. Basically, the jack has a small iron core within it, which generates the electromagnetism to transfer energy from source to destination. The amount of energy which can be transferred depends basically on the core size, number of turns, inductance and the waveform that is applied.

At the same time, the jack also makes use of a shielding technique which prevents any EMI/RFI interference from affecting the quality of the signal which is being transmitted or received. This helps to ensure that the data is transferred accurately and reliably without any loss. Apart from this, the jack also has features which suppress the radiated EMI, thus providing improved EMI/RFI shielding capability.

Conclusion

ARJM11B1-809-JA-ER2-T is an extremely useful jack with magnetics, which finds its use in many applications. It can transfer energy with high efficiency by using the inductive coupling method while also providing improved EMI/RFI shielding by its special shielding technique. It is especially suitable for PoE applications, as it can transfer power and data over a single cable, thus saving lots of time, energy and effort in setting up a network.
