Modular Connectors - Jacks

Modular jacks, also known as “modular connectors”, are used mainly in mobile and computer communication applications. These connectors are designed to board-to-board, cable-to-board, or cable-to-cable connections. They are available in multiple sizes, shapes, and materials. Jacks are an important component when it comes to providing reliable and secure connections between devices.

520242-2 is a single-piece, regular size, PCB-mount jack. It is made of polyamide thermoplastic material, and UL 94V-0 approved. It supports up to 2A current and is rated up to 700V AC. Its machined contacts ensure reliable connection and have long life & durability. It has a lead diameter of 0.9 - 1.2mm and a lead pitch of 8.4mm. Features such as a minimum vertical height, light to medium connection force, and easy to assemble makes it a perfect choice for applications that require reliable but low-profile connections.

The working principle of this connector involves a mating contact and a housing. The housing of the jack has two parts. The first is the housing body, which protects the connections and supports the contact and the second is the housing beam, which holds the contact in place. The contact has two terminals, i.e., front & back, which is connected to the header or the PC board. The contact has to be placed in the header or PC board with two fixing points. When the contact is placed on the header or PC board, the contact is locked by a housing beam. The housing beam ensures that the contact mates firmly and securely to the header or PC board.

520242-2 is mainly used in the telecom and datacom applications. These connectors are suitable for connecting DSL, xDSL, and T1/E1 circuits. As they are UL rated, they are best suited for in-building wiring. This jack can be used in RF and coaxial connections, voice applications, power supplies, and communication cables. They are also suitable for use in home security and fire alarm circuits.

520242-2 is an ideal low-cost, low-profile solution for applications that require reliable and secure connections. With its easy-to-assemble design, reliable connections, and medium connection force, this jack is an ideal choice for a wide range of applications in the telecom and datacom industry.
