Modular connectors, sometimes referred to as patch cords, are specialized electrical connectors designed for a variety of applications. The ARJM11C7-809-AD-ER4-T is a modular connector jack with magnetics which is particularly suited to a range of modern consumer electronics devices, from computers to smartphones to audio-visual equipment. This article will discuss the typical application fields for this type of connector and its various working principles.

The ARJM11C7-809-AD-ER4-T is a low profile, 1.25mm pitch connector ideal for use on tight PCB footprint designs. It offers a reliable connection between two components, with disruptive interference and leakage characteristics. Its low profile design also allows the connector to easily fit into most standard form factors, particularly for use in consumer electronics. This type of connector is most often used in applications such as USB ports, Ethernet ports, memory card slots, and audio ports.

The ARJM11C7-809-AD-ER4-T also offers excellent EMI shielding properties, preventing interference with neighboring electronic components. The high degree of shielding provided by this connector makes it an ideal choice for applications where there is a risk of interference due to close proximity of electronics, such as chasis-mounted ports. The modest size of these connectors make them a popular choice for use in smaller consumer electronics.

The ARJM11C7-809-AD-ER4-T offers enhanced electromagnetic compatibility (EMC) when compared to other types of modular connectors. This is due to the integrated ferrite core along the signal lines, which functions as a filter. This ferrite core acts to break up the electromagnetic signal over a wide range of frequencies, reducing the amount of interference and crosstalk between components. This advanced level of EMC also helps reduce environmental noise in sensitive environments, such as hospitals and data centers.

The ARJM11C7-809-AD-ER4-T’s primary working principle is based on the magnetics used in its construction. This type of connector uses an array of multiple magnets which create strong opposing magnetic fields to protect the signal from interference. This provides the connector with excellent protection against electrical noise, such as over-shoot and undershoot on signal lines, as well as radio frequency interference (RFI).

The ARJM11C7-809-AD-ER4-T is also designed with a power connector option, allowing the user to draw power from an external power supply. This power connector utilizes a modified version of the magnetics featured in the signal connector, as it must also provide a strong, reliable connection without interference. This enables the user to draw power from an external power supply while still taking advantage of the signal protection offered by the magnets.

The ARJM11C7-809-AD-ER4-T offers a wide range of uses and provides excellent protection against interference for users of consumer electronics. It is ideal for applications where tight form factor requirements are present, as it is exceptionally small and has excellent EMI shielding properties. The integrated ferrite core also helps ensure high levels of EMC, making it the perfect choice for users who require high performance and no problems caused by outside interference.
