Keystone Jacks vs RJ45 Connectors: What's the Difference?

Keystone jacks and RJ45 connectors are two terms that can confuse the world of network installation, which is why it's essential to know the difference between them.

While they may appear identical at first glance, they're very different in several ways, including their purpose, appearance, and use.

In this article, we'll talk about how these two essential pieces of equipment work and then examine some actual differences between them so you can choose which one works best for your network setup needs.

What Is a Keystone Jack?

A Keystone jack is a type of RJ 45 connector used in computer networking. It gets its name because it is often used in keystone modules, which are used in various types of patch panels.

 The most common type of keystone jack is the RJ 45 keystone jack, which connects Ethernet cables to network equipment in compliance with the EIA/TIA T568 A and B wiring schemes.

What Is an RJ 45 Connector?

An RJ 45 connector is a type of connector used in computer networking. It is named after the Registered Jack standard for telephone connectors, which it resembles.

RJ 45 connectors are used to connect Ethernet cables to network equipment.

Why Do I Need One in the First Place?

You will need a connector if you want to connect a device to an Ethernet network. The two most common types are keystone jacks and RJ45 connectors.

So, what's the difference between them? And why does it matter which one you use? While they both offer the same function in connecting your device to your network, they differ in how they deliver that signal.

RJ45 connectors have eight wires (4 pairs) that carry data through the cable from one side to another. A keystone jack is smaller than an RJ45 connector but offers all the same features with four wires that carry data through a cable from one side to another.

How to use Keystone jacks and Connectors

Keystone jacks and RJ45 Connectors are used in ethernet cable installation. They are both essential for a proper connection, but there are some critical differences between them.

RJ45 connectors have eight pins that must be aligned correctly for the connection to work properly. Keystone jacks have only four pins, which makes them easier to use and less likely to cause problems during installation.

Keystone jacks also have a locking mechanism that keeps the cable securely in place, while RJ45 connectors do not. This can be helpful if you need to move or rearrange your lines later.

Finally, keystone jacks are available in various colors, which can be helpful when trying to match up different cables or create a color-coded system.

How to Pick the Right One?

If you're working with Ethernet cables, you'll need to know the difference between an RJ45 connector and a Keystone jack. 

RJ45 connectors are the standard for connecting Ethernet cables to devices like computers, routers, and switches. A Keystone jack is a type of RJ45 connector used in patch panels and wall plates. 

The main difference between an RJ45 connector and a Keystone jack is that a Keystone jack has a removable plug that can be replaced with another type of plug. In contrast, an RJ45 connector is permanently attached to the cable. 

When choosing between an RJ45 connector and a Keystone jack, you should consider the type of application you're using it for. If you need to be able to replace the plugs on your Ethernet cables, then a Keystone jack is the better choice.

Which One Should I Buy?

If you're confused about which one to buy, don't worry - you're not alone. Here's a quick rundown of the difference between RJ45 connectors and keystone jacks RJ45 connectors are used for Ethernet cables that connect your modem or router to your computer or gaming console. In contrast, Keystone jacks can be used in modular panels in offices, schools, or conference rooms.

When looking at the two items side by side, RJ45 connectors are more minor than Keystone jacks, so they work better if you need more room for other things in your panel like outlets or USB ports.

Conclusion

In conclusion, the RJ 45 connector and the RJ 45 keystone jack are essential in different ways for Ethernet cable networking. The RJ 45 connector is responsible for connecting the line to the device, while the RJ 45 keystone jack is responsible for connecting the cable to the network. Both are essential in their way and serve different purposes.
