J00-0061NL Datasheet/PDFModular Connectors - Jacks With Magnetics
The J00-0061NL is an example of modular connectors, which are made up of a system of parts which can be snapped into a larger network and interchanged with ease. The J00-0061NL is specifically a jack with magnetics, which combines a standard RJ45 Ethernet jack with integrated magnetic transformers and circuitry.
Application Field
The main purpose of J00-0061NL jack is to reduce the amount of external devices needed in order to transmit a signal or data between two or more devices. It does this by combining the functions of an Ethernet interface, a transformer, and a signal splitter into one convenient package. The J00-0061NL can be used as a basic connection between a computer and the Ethernet network, or in more complex applications for audio, phone and data networks.
The J00-0061NL can also be used in applications that require specialised electromagnetic interference (EMI) protection, as the integrated transformer allows for excellent noise immunity. Furthermore, the integrated transformer also helps to minimise the amount of conducted noise which escapes onto the network, helping to keep the noise levels on the network low.
Working Principle
The J00-0061NL jack is made up of two main parts: the main body and the integrated transformer. Inside the main body is a centralised 8-paddle RJ45 connector, where the wiring is connected to the corresponding pins. This RJ45 connector is then connected to the local network, either through a patch panel or directly into a router.
The integrated transformer within the main body is responsible for converting the signals transmitted through the RJ45 connector. The transformer works by splitting the signal into two components: differential pairs and common-mode signals, more commonly known as the ‘twisted-pair’ and ‘shielded-pair’. The differential pairs carry the electrical signals, while the common-mode signals act as a reference to the differential signals. This helps to reduce the crosstalk between different signals on the network and provides better signal quality.
The J00-0061NL also includes built-in EMI protection to help reduce the amount of interference which can affect the transmission of signals. This is achieved by using a combination of capacitors and common-mode inductors, which are capable of absorbing and negating any sudden changes in the wiring, as well as any external interference.
Conclusion
The J00-0061NL is an example of modular connectors made up of a system of parts which can be snapped together into a larger network and then interchanged with ease. It combines a standard RJ45 Ethernet jack with integrated magnetic transformers and circuitry, enabling it to reduce the amount of external devices needed for signal or data transmission, as well as providing excellent noise immunity and EMI protection.
