What is the difference between RJ-11, RJ-45 & RJ-12 Connectors?

RJ-11, RJ-45, and RJ-12 connectors might look similar at first glance, but they each have their own unique roles:

• RJ-11 Connectors: These smaller units are the standard for telephone lines. With four positions and two or four contacts, they’re perfect for hooking up your phone or even a fax machine.
• RJ-12 Connectors: Think of RJ-12 as the big sibling to RJ-11. It has six positions and six contacts, making it ideal for more complex phone systems, like the ones in offices.
• RJ-45 Connectors: The heavyweight champ of networking, RJ-45 connectors boast eight positions and eight contacts. They’re your go-to for Ethernet cables and ensuring your data zips along smoothly.

Is RJ-11 still used?

While some may have moved to VoIP and other digital communication methods, RJ-11 connectors are still widely used worldwide, especially in homes and small businesses. They’re reliable, straightforward, and perfect for traditional landline phones. Plus, they’re often the best option available in areas where internet access is spotty.

What is the difference between RJ-45 & Cat6?

RJ-45 is a type of connector, while Cat6 refers to a category of Ethernet cable. The magic happens when you pair an RJ-45 connector with a Cat6 cable, as Cat6 cables can handle higher speeds and more bandwidth than their Cat5e counterparts.

If you’re looking to stream the latest shows without a hitch or keep your online gaming lag-free, going with Cat6 and RJ-45 is a smart move.

What does RJ connector stand for?

RJ stands for "Registered Jack," a standardised network interface that seamlessly connects your telecommunications and data equipment. The numbers accompanying the RJ (like 11, 12, and 45) refer to different connector configurations, specifying the number of positions and contacts. Standardisation ensures that it'll fit perfectly no matter what device you’re using.
