Modular Connectors - Jacks with Magnetics describe a variety of connectors widely used in many different applications. One example is the J0026D21. This particular type of connector is designed with a special internal magnet that is used to reduce crosstalk and EMI (electromagnetic interference) in applications with high frequencies.

The J0026D21 consists of a polarized inserted end and a two-piece outer shell with a jack. This particular connector is available in a variety of form factors including vertical, horizontal, and right-angle. The two components of the J0026D21 are the signal contacts and the magnet. The signal contacts are located inside the jack and are made of either phosphor bronze or beryllium copper. These contacts are spaced apart from each other to reduce crosstalk and EMI. The internal magnet is used to control the electrical characteristics of the connector, such as signal transmission loss. The magnet is constructed with Neodymium Boron and Nickel Ferrite, creating an effective metal-to-metal contact between the jack and the substrate.

J0026D21 connectors are used in a wide range of applications, including data transfer and communication equipment. They are commonly used in telecommunications, data centers, industrial networking, and medical and military applications. The main advantage of using this connector type is that it offers better crosstalk and EMI suppression compared to traditional connectors. This is because the internal magnet creates a metal-to-metal contact between the jack and substrate, reducing the signal losses that can cause interference. Additionally, the connector is designed to be low-profile, so it won’t interfere with the routing of other cables in the same area.

The working principle of the J0026D21 connector is simple yet effective. When the signal contacts are inserted into the jack, the internal magnet creates a metal-to-metal contact, which reduces any crosstalk or EMI between the two connection points. This minimizes signal losses, resulting in a more reliable data transfer connection. The connector is also designed to provide durability, as it can resist shock and vibration better than traditional connectors.

The J0026D21 is an effective connector type that can be used in a variety of applications. It not only offers better crosstalk and EMI suppression, but is also designed for improved durability. Its design also helps to reduce routing disruption, as it can fit into a narrower space than other connectors. As a result, the J0026D21 is an ideal choice for high-frequency data transfer applications, where high levels of reliability are needed.
