Modular Connectors - Jacks With Magnetics

Modular connectors, also known as jacks and jack sockets, are electronic connectors that attach to cables for the purpose of connecting multi-pin interfaces to a panel-mounting plug. Such connectors are mainly used as easy-to-use and inexpensive connectors for datacom and telecom equipment in short runs which are primarily used for patch cords or connecting telephones. One type of modular connector is the A63-114-300P131 jack with magnetics.

A63-114-300P131 Application Field and Working Principle

The A63-114-300P131 jack with magnetics is an Ethernet connector designed for connecting two circuits where one is required to be more noisy than the other. It is designed for balanced differential circuits, and is primarily used in applications such as Ethernet 10Base-T, 100Base-T, and LAN—local area network—applications. It is compliant with the TR-41.19 standard and is rated up to 1.2 kVrms for contact to contact and contact/shell.

The A63-114-300P131 features two shielded, opposed plastic shells, with each shell having an area that contains four rows of 20 removable, high power-rated terminal receptacles. These receptacles feature a flexible design for secure connections, and are constructed for a minimum contact pressure of 2 pounds. The receptacles interface with a housing on the circuit board, and the entire structure is designed as a secure, reliable, and easy-to-install modular connector.

The working principle of the A63-114-300P131 jack with magnetics is based on providing differential pairs of high-speed line signals by using high-power magnetics. The signal pairs are transmitted through separate channels, so that one pair can be virtually noiseless while the other carries a noisy signal. The two channels are connected through a screening foil of a very short length, thanks to which the noise on one channel is not transmitted to the other channel. This applies a filtering effect to the differential signal pair, reducing EMI and maintaining a greater signal integrity over longer cable lengths.

The A63-114-300P131 is also designed to work in high vibration environments, offering superior flexibility and resistance to shock and vibration. Its construction, which is plastic and metallic, ensures that its electrical performance is maintained over time. It is also EN 50-0937-012 and EIA-3239 compliant and has been tested to UL 5048F, CSA C22.2, and IEC67-2-53 standards.

Thanks to its wide application field, good performance, and reliable construction, the A63-114-300P131 jack with magnetics is the preferred choice of connectivity for many applications.
