Keystone Jacks ethernet 110 type punch down rj45

Keystone jacks are a type of connector used in Ethernet networking applications to terminate Ethernet cables and create a connection between the cable and a wall plate, patch panel, or other network equipment. They are named after their shape, which resembles a small, rectangular keyhole.

Keystone jacks for Ethernet are available in a variety of types, including RJ45, which is the most common type used for Ethernet networking. They are designed to fit into keystone openings in a wall plate or patch panel, allowing for easy installation and customization of network connections.

Ethernet keystone jacks typically consist of a plastic housing that contains a set of contacts for the eight wires in an Ethernet cable. The contacts are arranged in a specific configuration that corresponds to the wiring scheme used for Ethernet, which is typically T568A or T568B.

When an Ethernet cable is inserted into the keystone jack, the wires are inserted into the contacts and crimped or punched down to create a secure connection. The keystone jack is then snapped into the keystone opening, creating a neat and tidy connection that can be easily plugged and unplugged as needed.

Keystone jacks for Ethernet are available in a variety of colors and styles, including shielded and unshielded versions, as well as versions with angled connectors or strain relief features. They are commonly used in commercial and residential installations, including offices, data centers, and homes, and are a reliable and cost-effective solution for terminating Ethernet cables and creating network connections.
