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](https://uk.rs-online.com/web/c/cables-wires/networking-coaxial-cables/ethernet-cable/). The sockets or jacks are generally embedded in the device that is being hooked up or mounted to a fixed wall panel.

RJ11 Connectors | RS

<p>RJ11 connectors, or Registered Jack Connectors, are connectors which are standardised for telecommunication network interfaces. They work with audio and data devices and allow them to communicate with service providers.</p><h2>What are male and female RJ11 connectors?</h2><p>The connectors are available in male or female genders. Male RJ11's are paired with wires which are attached to contacts on the connector. The connector piece will slot into a socket on the device, for example, a telephone. This socket is the female RJ11 connector.</p><h2>What are they used for?</h2><p>The RJ11 is used for plugging in telephone handsets to wall receptacles and is commonly used for this purpose in many countries around the world and also used with modems. Our range of RJ11's include plugs and sockets for modular and PCB mounting and are available either unshielded or shielded. There are even ATEX versions available for hazardous environments.</p>

RJ45 Connectors | RS

<p>RJ stands for registered jack which is a standardised networking interface.</p><h2>What are RJ45 Connectors used for?</h2><p>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. These plugs are then inserted into the RJ45 jacks on the Ethernet device.</p><h2>Types of Registered Jack connectors</h2><p>Several other kinds of connectors closely resemble RJ45 and they can be easily confused for one another. The RJ11 connectors used with telephone cables, for example, use six position connectors rather than eight position connectors, making them slightly narrower than RJ45 connectors. 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.</p><p>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.</p>

It's a type of connector with eight pins and is commonly used to connect computers, routers, switches, and other network devices to each other or to a network infrastructure. The term "RJ45" stands for Registered Jack 45.</p><p>RJ45 connectors are typically used with twisted pair cables, such as Category 5 (Cat5), Category 5e (Cat5e), Category 6 (Cat6), or Category 6a (Cat6a) cables, which are commonly used in Ethernet networking. Samtec connectors are designed to securely snap into Ethernet ports and maintain a stable connection for data transmission.</p>
