RJ45 Connectors
RJ45 or Registered Jack 45 connectors are a standardised type of connector for networking. A male to male RJ45 cable is more often referred to as ethernet cable or networking cable. Predominantly the RJ45 sockets are board or panel mounted and this is true of all our RJ45 connectors. These rugged connectors are also waterproof, environmentally sealed to IP67 or IP68 and are available in both plug and jack styles.

View ProductFrequently Asked Questions about RJ45 Connectors
An RJ45 connector is a standardised type of connector used for networking. Its full name is registered jack 45 and it has an 8 pin 8 contact configuration (8P8C). These are more commonly known as Ethernet cables and sockets which are found in many server and networking cabinets as well as PC’s, gaming consoles and internet routers.
There is no single best RJ45 connector. They are all designed to perform under different criteria, to discuss your application please contact the Live Electronics Ltd Sales Team.
The only differences between RJ45 connectors is their pin layout and what category of cable they are designed to be used with.
No, Cat 5 or more commonly Cat5e connectors have a straight pin layout whereas Cat6 connectors have a staggered pin layout. This is because the staggered layout is beneficial in reducing cross-talk interference. In conjunction with the design of Cat6 cable, this enables higher data transfer speeds of max 10Gbps up to 55 meters compared with 1Gbps at 100m for Cat5e.
No, an RJ45 connector cannot be reused. This is because the connector pins need to be crimped onto the wire, once crimped it is not possible to un-crimp the connector and the wire will need to be cut and a new RJ45 connector attached in its place.
RJ11 and RJ45 are both styles of registered jack, however, the RJ11 has 4 wires while the RJ45 has 8 and as such an RJ45 is visually wider than an RJ11 connector.
RJ45 is the name of the connector itself, standing for registered jack 45, this is the standardised connector used for ethernet connections. As such the ethernet cables are sometimes called RJ45 cables.
