Rj11 vs Rj22: Difference and Comparison

Telecommunication was once used in households and workspaces, but now the use of telephones has become limited.

Although they provide Ethernet services, they require wire connectors or Registered Jacks, which come up with many configurations and are used in telecommunication exchange companies. And some of them are named – Rj11, Rj25, Rj12, Rj22, Rj9, etc.

Key Takeaways

  1. RJ11 and RJ22 are telephone connectors, but RJ11 is a 4-wire connector, while RJ22 is a 2-wire connector.
  2. RJ11 is commonly used for connecting telephones, modems, and fax machines, while RJ22 is used for connecting handset cords.
  3. The physical differences between RJ11 and RJ22 connectors are their size and their number of contacts. RJ11 has six contacts, and RJ22 has four contacts.

Rj11 vs Rj22

RJ11 or registered jack 11 is a square-shaped plastic telephone interface with a 6P4C and 6P2C configuration. It can only handle 2 or 4 wires. RJ22 is a modulator used to connect electrical appliance wires to audio headsets, telecommunication and networks. It has a 4P4C configuration which can handle four wires.

Rj11 is a registered jack with a configuration of 6P4C and 6P2C. It is a commonly used registered jack for telecommunication companies.

Rj11 can be used for single-line telecommunication in many countries except the United States. It has copper pins as conductors with a gold coating over it to prevent it from rusting.

Rj22 comes with a configuration of 4P4C which means 4 Positions and 4 Connectors. Rj22 is not a registered jack but unofficially is a part of it. The Rj22 port is used in telephone handsets.

It also has a capacity of holding 4 wires simultaneously but unfortunately has limited use. The copper pins are used as conductors and are plated with gold to prevent rusting.

What is Rj11?

Rj11 is a registered jack invented in the United States in the 1970s. The purpose of these registered jacks is to connect the long-distance carrier to a voice or data equipment device.

It is the most common registered jack used. It is a connector for connecting single-line live wires of telephone exchange companies.

The physical appearance of the device is compact and square-shaped size. Also, it is available in two configurations – one is 6P4C, and the second one is 6P2C.

After decoding these names, it is meant for 6 positions and 4 connections, 6 positions and 2 connections.

The device with the 6P4C configuration can handle the four wires simultaneously, while the device with the 6P2C configuration can handle only two.

Rj11 comes up with copper wire pins used as conductors and is plated with gold to avoid rusting. The advantage of using Rj11 is that it comes with a dual configuration, and the body of the device is made of plastics, making it more durable and easier to use.

It also comes with one disadvantage it cannot handle heavy transmissions.

What is Rj22?

Rj22 is not a registered jack but a modulator that connects cables and wires of other electrical appliances in computer networking, telecommunication equipment, and audio headsets.

The physical appearance of the Rj22 device looks similar to Rj11 but differs in configuration and shape. Rj22 is a small square-shaped device with a configuration of 4P4C.

The decode meaning is that it comes with 4 positions and 4 connections. The body of the Rj22 device is made up of rigid plastic.

It also allows visibility of the connected wires to look through it.

Rj22 has copper pins that work as the conductor and are gold-plated to avoid rusting. These are used mainly in telephone handsets.

The advantage of using Rj22 is that it is durable because the device’s body is made of plastic. The look of the device is appealing.

This device can handle 4 wires simultaneously. However, it is limited because it can only be used in telephone handsets.

Main Differences Between Rj11 and Rj22

  1. The Registered Jack 11 has two configurations of 6P4C (6 Position 4 Conductor) and 6P2C (6 Position 2 Conductor). In contrast, the Registered Jack 22 comes with 4P4C (4 Position 4 Conductor).
  2. The Rj11 is made of transparent plastic, a compact and square-shaped device. In contrast to that, Rj22 is comparably small and square-shaped.
  3. As Rj11 has two configurations, i.e. 6P4C and 6P2C, the first device can hold 4 wires, and the second one can hold 2 wires, while Rj22 can hold 4 wires simultaneously.
  4. Rj11 is used in telephone lines and modems. On the other hand, Rj22 is used for a telephone handset. 
  5. A significant disadvantage of Rj11 cannot hold heavy transmission while Rj22 is that it can only be used for a telephone handset.
