Modular Connectors - Jacks With Magnetics

The V890-1AX1-A1A are magnetic modular connectors, otherwise referred to as “jacks with magnetics”. This type of modular connector utilizes magnetics to provide protection against EMI (electromagnetic interference) and other electrical noise. The magnetic shield on the unit helps to minimize the amount of electrical interference on the circuit, keeping it more reliable and stable.

Application Field

V890-1AX1-A1A jacks with magnetics are primarily used in industrial systems where EMI protection is critical. These magnetics are frequently found in data communication systems, such as LAN (Local Area Network) connections, as the magnetic shield helps to reduce the amount of interference that can create transmission errors. The V890-1AX1-A1A is also suitable for high-speed communication systems, especially those with high bit rates.The V890-1AX1-A1A jacks with magnetics are also found in cable assemblies, such as USB (Universal Serial Bus) and IEEE 1394 (power) connections. In these type of connections, the magnetic shielding helps to ensure that signals are not interfered with by external electromagnetic noise.

Working Principle

The working principle of the V890-1AX1-A1A jacks with magnetics is quite simple. The magnetics within the connector create a shield around the connection point by providing a current path for high frequency electrical interference, which then helps to isolate the circuit from external electrical noise. The magnetic fields generated by the magnetics alter the direction of the EMF waves that are hitting the connector, creating a kind of “dead zone” within the circuit. As long as the magnetic field generated by the V890-1AX1-A1A is strong enough, the electrical interference is cancelled out by the interaction of the field and the EMF waves.

Advantages

The primary advantage of the V890-1AX1-A1A modular connectors is that they provide a very effective means of protection against EMI. This type of modular connector is very reliable, and can be used in many different applications where EMI is a major concern. Furthermore, these jacks with magnetics offer a very low profile, making them ideal for applications where space is at a premium. In addition, the V890-1AX1-A1A are also relatively easy and cost-efficient to implement. The components are small and lightweight, meaning they can be easily integrated into existing systems or new systems without having to install additional wiring or hardware. Additionally, the overall cost of the V890-1AX1-A1A is lower than that of other types of EMI protection, making it a very attractive option for many manufacturers and end-users.

Conclusion

The V890-1AX1-A1A jacks with magnetics are a useful and cost-effective way of providing EMI protection for many different types of industrial systems. This type of modular connector has proven to be very reliable in applications where high-speed data communication is required, and is also well-suited for systems where space is at a premium. Furthermore, the overall cost of the V890-1AX1-A1A is lower than that of other types of EMI protection, making it a very attractive option for many manufacturers and end-users.
