Modular Connectors - Jacks With Magnetics

The ARJM11A3-809-JA-ER4-T is a jack with magnetics, a type of connector that is designed to provide power and reliable data communication signals from the system to the peripheral device, while offering a secure connection in a variety of environmental conditions. This type of connector is often used in Ethernet networks, allowing multiple devices to be connected to a larger network, and can also be found in the automotive and industrial sectors.

Application Field

The ARJM11A3-809-JA-ER4-T is a common choice for network infrastructure and applications, especially in demanding industrial environments. Its robust construction and excellent protection from electromagnetic interference (EMI) makes it suitable for applications where normal contact wear can occur, such as office or factory environments with regular changes in personnel. In addition, its ability to transfer both data and power allows it to securely and reliably connect multiple devices in a single network, reducing cabling costs and optimizing network performance.In the automotive sector, this connector is ideal for use in the design of electric and hybrid vehicles. Its robust construction and good resistance to wear and tear offer reliable and safe connections between components such as battery packs and controllers. The connector also has a wide temperature range, meaning it can handle the harsh environment found in most cars.The ARJM11A3-809-JA-ER4-T is also widely used in home and building automation. Its small footprint and cost-effective design make it ideal for wiring systems in residential and commercial buildings, while its ability to quickly and easily connect and disconnect devices makes it perfect for applications such as lighting control and security systems.

Working Principle

The ARJM11A3-809-JA-ER4-T is essentially a jack with contacts and a ferrite core. This ferrite core provides a level of electromagnetic interference suppression that connects it to other devices or components on the network. The contacts are arranged into an array of four pins, and the connector is soldered directly onto a printed circuit board.When two of these jacks are connected, an electrical connection is established, allowing power and data to flow from one end to the other. The pins on each connector engage, forming a secure and tight fit. Once connected, the ferrite core suppresses any interference that may be present in the signal, ensuring a reliable connection.The ARJM11A3-809-JA-ER4-T is a reliable and cost-effective solution for a wide range of applications. Its robust construction and excellent protection from EMI make it an ideal choice for network infrastructure, while its ability to quickly connect and disconnect multiple devices also makes it suitable for home and building automation systems. The connector also has a wide temperature range, so it can accommodate the tough environmental conditions found in automotive and industrial applications.
