Keystone connectors are a type of electrical connector that are commonly used in structured cabling systems. Keystone connectors are rectangular in shape and have a series of contact pins or pads on the bottom side, which mate with a complementary connector on the back of a keystone jack or wall plate.
Keystone connectors are commonly used to connect twisted pair or coaxial cables to patch panels, wall plates, or other types of cabling infrastructure. They are available in different sizes and styles, depending on the specific requirements of the application. Keystone connectors can be used to connect cables that are parallel or perpendicular to the connector, and are often used in conjunction with other types of connectors, such as modular connectors or panel-mount connectors, to provide a complete connectivity solution.
Keystone connectors are typically easy to install and remove, and can be snapped into or out of the keystone jack or wall plate using a simple tool or by hand. This makes them a popular choice for applications where cables need to be frequently added, removed, or reconfigured.
