Ethernet Connectors

Ethernet connectors are used for Ethernet networking such as telecommunications or data equipment. The ethernet connectors are connected to each end of an Ethernet cable. Ethernet connections between devices provide a reliable, stable and interference free connection with fast data transfer speeds and are sometimes more preferred than wireless or Wi-Fi networks.

The RJ45 connector is the most commonly known type. RJ45 connectors have an 8P8C (8 position, 8 contact) configuration. In order for the connector to function properly, the individual Ethernet cable wires must be inserted into these locations following a T-568A or a T568B wiring standard. Technically, 8P8C can be used with other types of connections besides Ethernet; it is also used with RS-232 serial cables, for example. However, because RJ45 is by far the predominant usage of 8P8C, industry professionals often use the two terms interchangeably. RJ45 connectors are available to suit a range of LAN categories from Cat3 to Cat6a. Different mounting options are also available, including cable mount, PCB mount and panel mount.

Ethernet networks are very common in domestic and working environments. A network is simply several interconnected devices that are capable of sharing data between one another. Home networks are usually based around a router or modem, connected to various other devices such as PCs and laptops, smart TVs, mobile phones, games consoles, media servers and printers. A domestic setup of this kind is an example of a LAN (Local Area Network). The name comes from the fact that all devices linked to it are close to the others, typically within the same building.

Types of RJ Connectors


  • RJ11
  • RJ12
  • RJ22
  • RJ25
  • RJ45
  • RJ48
  • RJ50

RJ45 connector is used today to describe both male RJ45 plugs and female RJ45 sockets. The plugs, sometimes called modular connectors, are usually found on the end of Ethernet cables. The sockets or jacks are generally embedded in the device that is being hooked up or mounted to a fixed wall panel.

Other types of Ethernet connectors

Mini IO connectors are small wire-to-board interfaces suitable for most environments. These connectors are easily installable without the need for wire termination and soldering activities. A mini IO connector consists of a housing, a shell and a terminal with contact points. The outer materials are made from thermoplastics, which makes them highly resistant to shock, vibration and extreme temperatures. The terminals have contacts made of copper alloy, which increases conduction for highly reliable connection features. Latch mechanisms prevent cables from pulling out of the mini IO connectors.

What are RJ connectors used for?

RJ stands for registered jack which is a standardised networking interface. RJ45 connectors are used for connecting Ethernet cables to equipment in computer networking applications such as telecommunications or data equipment. RJ45 connectors consist of modular jacks and plugs. The RJ45 plugs are connected to each end of an Ethernet cable
