Modular cables or connectors are a family of sockets and plugs with registered jack twisted pair cables. They are identified by the number of positions on the connector that can hold a wire contact and the real number of contacts. For example, a 6P2C connector indicates that it has two positions and six contacts. This may represent the numbers but does not indicate the purpose of the wires. Modular connectors are electrical cables developed for cords and cables of electronic devices such as computers, telecommunication equipment, and audio equipment or headsets. However, the most commonly used modular cables are in the telecommunications applications like Ethernet and telephone.
Why Should You Buy Modular Connectors?
As already mentioned, modular connectors are commonly utilized for telephone systems, data networks, and low-speed serial connections. These connectors are highly preferred because they are inexpensive, simple, easy to terminate, and easy to plug and unplug. It usually consists of a clear, plastic body featuring a tab that holds the plug and jack into place when connected. The terminologies used by industries are widely referred to as RJ connectors. This naming convention could be inaccurate but is widely used. RJ means registered jack, part of a coding system developed in the 1970s to classify telephone equipment and services.
Telephone and Ethernet
The most common modular connectors are utilized to plug a telephone effectively into a wall outlet. This also includes the handset that comes with the phone. They are also known as the plugs and sockets of RJ-45 Ethernet cables.
Gender
Modular connectors have two genders; the plugs are known as male, while the jacks or sockets are known as female. Plugs are used to eliminate cables and cords, while jacks are used to fix certain areas on wall surfaces, equipment, and panels. Besides telephone extensions, cables consisting of a modular plug on one end and a jack on the other are not common. Therefore, the cables are more commonly connected using a female-to-female coupler, featuring two back-to-back wires.
Latching Tab and Orientation
Most modular connectors are planned with a latching system that gets the actual association. As a fitting is embedded into a jack, a plastic tab on the plug locks against an edge in the attachment, so the fitting can't be removed without separating the tab by squeezing it against the fitting body. The standard direction for introducing a jack on an upward surface is with the tab down.
The secluded fitting is frequently introduced with a boot, a plastic covering over the tab and body, to forestall the locking tab from guiding into different cords or edges, which might cause excessive bowing or breaking of the tab. Such Snagless lines are typically developed by introducing the defensive boot before the secluded fitting is creased.
Size and Contacts
Modular connectors are usually designated by using only two numbers that indicate the maximum number of contact positions and the number of installed contacts, with each number having letters P and C, respectively. For example, 6P2C is a connector with six positions and 2 contacts. When they are not installed, the contacts are commonly omitted from the outer position o inward, given that the number of contacts is almost always even. RJ11 cables are commonly found to have six positions and four contacts.
Modular connectors are usually produced in four sizes with 4-, 6-, 8-, and 10-positions. The plastic insulating bodies of 4P and 6P connectors have varying widths, whereas the 8P and 10P connectors have similar larger bodies.
