Modular Connectors - Jacks With Magnetics refer to connectors that involve the use of a magnet. This type of connector typically combines the features of a modular jack and a transformer, providing a single connection point for both telecommunications and power data transfer. The ARJM11C7-116-JA-EW4 variant is no exception, featuring a combination of power, audio, and common mode protection circuitry. This article will cover the application field and working principle of the ARJM11C7-116-JA-EW4.

Application Field of ARJM11C7-116-JA-EW4

The ARJM11C7-116-JA-EW4 variant of modular connectors specifically targets low-power applications such as wireless networks, as well as multimedia and communications equipment. It is designed for use with power supplies outputting up to 40 volts DC, and is also suitable for microphone connections. It also has the ability to interface with dry contact switchs, making it a viable, cost-effective solution for most low-power application.

In terms of physical structure, the ARJM11C7-116-JA-EW4 features two shielded jack connectors, each with 8 contacts. One of these two jacks serves as an input port, while the other is an output port. Between these jacks lies the magnetics subassembly, made up of two ferrite cores and a common mode choke. This magnetics subassembly provides both electrical isolation and power distribution, allowing it to be used without a separate power supply.

Working Principle of ARJM11C7-116-JA-EW4

The working principle of the ARJM11C7-116-JA-EW4 revolves around its magnetics subassembly. This component uses two ferrite cores with an air gap in between them, allowing them to magnetically induct signals from the two jacks and ignore any other signals from outside the ARJM11C7-116-JA-EW4. This makes the connector ideal for low-power and signal-sensitive applications.

The electrical signals from the two jack connectors are then taken by the magnetics subassembly and passed through the common mode choke. This prevents any noise or other interference signals from entering or leaving the device, ensuring that only the designated signals are passed through.

Once the signals are through the common mode choke, they are passed to a rectifying diode, allowing DC current to be used to power the device. This diode also limits the amount of current that can pass through the ARJM11C7-116-JA-EW4, thus providing additional protection to the device and the connected equipment.

Finally, the ARJM11C7-116-JA-EW4 also has the ability to switch between two different operating modes, thanks to its microcontroller. This switch can be used to toggle between two different data transmission signals, thus allowing the connector to be used in a variety of different applications.

Conclusion

In conclusion, the ARJM11C7-116-JA-EW4 variant of modular connectors - jacks with magnetics provides a reliable and cost-effective solution for low-power applications. Its combination of a magnetics subassembly and a rectifying diode allows it to provide both electrical isolation and power distribution, making it suitable for both communication and power data transfer. Its ability to switch between two different operating modes further enhances its capability, making it a viable option for a wide range of applications.
