Ethernet Connectors

Ethernet connectors are used for Ethernet networking such as telecommunications or data equipment. The connectors are connected to each end of an Ethernet cable. 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.

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.


Frequently asked Questions


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
