What is a RJ45 Keystone Jack?

RJ45 keystone jack is an important component of a local area network. It is a standardized interface module commonly used for network connections, used to connect computers, routers, and other network devices. It can provide reliable and high speed data transmission, enabling effective communication and data exchange between network devices, has been widely used in various Ethernet networks.

Category of Keystone Jack

Ethernet cables have different categories due to their different performance. Network keystone jacks are also classified into different categories based on the specifications of the network cables they support, mainly including CAT5E, CAT6, CAT6A, CAT7, and CAT8 RJ45 keystone jacks.

Matching Ethernet keystone jacks with corresponding category network cables can fully leverage performance advantages to achieve the required network transmission speed and performance.


Category Transmission Frequency Transmission Speed Application
CAT5E 100Mhz 1000Mbps 1000Base-T Ethernet
CAT6 250Mhz 1000Mbps 1GBase-T Ethernet
CAT6A 500Mhz 10Gbps 10GBase-T Ethernet
CAT7 600Mhz 10Gbps 10GBase-T Ethernet
CAT8 2000Mhz 40Gbps 40GBase-T Ethernet

Types of Keystone Jacks

There are many types of keystone jacks available to meet different network applications and environments. According to different standards, they can be classified into different types.

By Shielding Type

Unshielded Keystone Jack

Unshielded RJ45 keystone jacks are currently one of the most mainstream network keystone jacks in the market, due to the widespread use of unshielded Ethernet cables. Its shell is made of plastic, usually PC or ABS material. Due to the absence of additional metal shielding structures, UTP keytone jacks have lower resistance to electromagnetic interference and are more suitable for general home and office network environments.

Shielded Keystone Jack

Shielded keystone jack has a specially designed shielding structure, the shell is made of metal or alloy materials, which can effectively block external electromagnetic interference, reduce signal propagation loss and attenuation. STP keystone module is very suitable for environments with high electromagnetic interference.

By Wiring Method

Punch Down Keystone Jack

Punch down keystone jack requires specialized wiring tools during the installation of network cables, which can ensure reliable contact performance, usually used for network installation applications that require higher reliability and durability. In addition, the IDC of the keystone can also be divided into 110, krone, dual, which means using different types of punch down tools. 110 is commonly used in the Americas, while krone is more popular in Europe.

Toolless Keystone Jack

Toolless keystone jack does not require additional tools during wiring, aiming to minimize operating steps and make wiring easier for users. This type of keystone jack is commonly used in home networks and small office environments, with faster and more convenient connections.

90 Degree Keystone Jack

90 degree keystone jack refers to a keystone jack whose IDC is at a 90 degree angle to the RJ45 socket.

90 Degree Keystone Jack

180 Degree Keystone Jack

180 degree keystone jack refers to a keystone jack whose IDC is at a 180 degree angle to the RJ45 socket. There is no performance difference between it and the 90 degree jacks, the specific choice depends on the habits of the application market.
