Dummy’s Guide to Buying RJ 45 Connector in 2024 [New]

Rj45 connectors are arguably the most complex components of wired LAN networks. Their design is quite complicated when you compare it to the pretty straightforward internal cores of the bulk ethernet cables.

And there are multiple methods of installing them. More importantly, they come in multiple shapes and sizes, which makes both the process of buying and installing them a bit more complex.

Now, how do you actually buy them? This is the question we are dealing with today. In this blog, we will walk you through the process of choosing the right rj45 crimp connectors. Then we will explore how to buy the Rj 45 connector. Finally, you will also learn insider techniques for installing these cables the right way. Be sure to read till the end.

What are RJ45 Connectors?

RJ stands for registered jack and 45 refers to the listing number of the modular connector.

It has an 8p8c modular design. The 8p stands for 8 positions and the 8c stands for 8 contacts. When an ethernet cable is terminated into this connector, the 8 wires of the cable connect to the 8 contacts. These contacts then connect with the contacts of the female RJ45 keystone jack which makes the transfer of data and power in PoE possible. 

Types of RJ45 Connectors

There are a variety of rj45 connectors. For instance, there are connectors for different ethernet cables such as cat5e, cat6, and cat6a. You can also use the same connector for other cables if the wire gauge of the cable is compatible with that of the connector.

Then there are shielded and unshielded connectors. This classification is dependent on whether or not the modular connector has shielding. Needless to say, the shielded connectors are more expensive than their unshielded counterparts. And hence, they work much better in EMI and interference-intensive environments.

Then there are RJ45 crimp connectors. Crimp refers to the way they are terminated. Their counterpart connectors are pass-through. Pass-through connectors are easier as compared to crimp connectors when it comes to termination.

While shopping, you need to be aware of all these types so as to ensure that you buy the right ones for your needs.

Ethernet Cable and RJ45 Connector Compatibility

What happens sometimes is that people buy their bulk ethernet cables from one brand and their connectors from others. This can be a bit problematic. If the cables and connectors you have bought are not compatible, you cannot terminate the wires.

It is also important to mention here that ethernet cables can have varying wire gauges. For instance, cat5e cable can be between 23 to 25 AWG. This means if you have bought a 24 AWG connector for the Cat5e cable having 23 AWG wires, it will not work.

So that is why it is important to buy your ethernet cables and the connectors from the same place. If that is not possible, make sure you buy the cables and connectors that are compatible with one another.

How to Buy RJ 45 Connector?

Well buying the rj45 connectors is an easy task. However, you need to know the different types available on the market. And more importantly, which connectors you need. 

First figure out what you need

First, figure out what you need. Have you decided which cables you are installing? And if you have already installed it, then this step will be easy. Simply find out the wire gauge of your ethernet cables and that is what you need to make sure that your connectors also have. 

Choose the type of connector

Then, you will need to figure out the type of connector you need. You can choose between passthrough RJ45 crimp connectors and regular ones. Note that the pass-through connectors are easier to terminate and allow more accurate alignment of the wires.

In the regular connectors, you cannot pass the wires through it. This creates two problems. First, it doesn’t allow you to align the wires properly. And secondly, you cannot crimp the wires tight enough.

So prefer to buy rj 45 crimp connectors over the regular ones. Crimp 8p8c modular connectors are also known as EZ connectors. 

Buy RJ45 Modular Connectors

Once you are done figuring out the type and category of your connectors, it is time to make the purchase. But first, you will need to choose a vendor. Since you will most likely buy them online, simply look up for ‘buy r45 connectors’

This will prompt you with a long list of vendors who are selling the connectors online. Now taking into consideration, the number of reviews and star ratings, choose one.

Make sure the vendor you have chosen is trustworthy. And that the product they will supply will be of high-quality.

Once you are done with confirming the social proof, you can place your order.

Pro Tip: Make sure you are confirming the compatibility of your cables with the RJ45 connector you are buying.

Final Thoughts

In short, you can buy rj45 connectors by simply figuring out which 1000ft bulk ethernet cables you use and which 8p8c modular connectors you need. You also need to choose between the pass-through and regular male connectors before choosing a vendor and placing your order. We hope this blog was of help to you.
