1. What are Modular Connectors - Jacks With Magnetics?
Modular Connectors - Jacks With Magnetics are modular connectors with integrated magnetic components, mainly used in high-speed data transmission scenarios such as Ethernet. Magnetic components (such as transformers and filters) are used for signal isolation, impedance matching and anti-electromagnetic interference (EMI), ensuring the stability and reliability of data transmission.
-
2. Why do we need to integrate magnetic components?
The main purpose of integrated magnetic components is to meet the requirements of Ethernet standards such as 10/100/1000 Base-T and PoE. Magnetic components provide electrical isolation, signal balance and transient protection, while reducing electromagnetic interference (EMI), ensuring the stability of high-speed data transmission.
-
3. How to distinguish different models of Modular Connectors - Jacks With Magnetics?
Models are usually distinguished by the following features:
Port configuration: such as 1x1, 1xN or 2xN.
Rate: such as Cat5e, Cat6 or Cat6A.
Mounting direction: right angle or vertical mounting.
Additional features: such as LED indicator or shielding design. -
4. Do these connectors support high-reliability (Hi-Rel) applications?
Yes, many Modular Connectors - Jacks With Magnetics are designed for high-reliability scenarios, with EMI/RFI shielding, protective shell and high durability, suitable for military, aerospace and industrial automation.
