RJ45 Crimper

RJ45 crimper, as we all know, is one of absolutely necessary tools in Ethernet cable wiring. This is because RJ45 crimpers are the excellent helper to ensure the good network connection for you. Actually RJ45 crimp tool is more than just a cable crimper. These RJ45 crimping tools are really versatile. It can cut cat5 cable, strip wire, and crimp RJ45 connector as well.

If you fail to choose the right RJ45 crimping tool, not only does it waste RJ45 jack, Ethernet cable and other material, it also brings about hidden peril to the follow-up work. So, when it comes to choose a quality cat5 crimping tool, you need to learn a thing or two about this RJ45 tool.

Types of wire crimper

It is very important to pay attention to choose the right type of cable crimp tool as there are so many similar crimping tools such as Molex crimper and coaxial cable crimper available at retail outlets. That means you have to use the dedicated crimp tool according to the different connectors and cables as you require.

Don’t mix up with Molex crimper

For example, to cut, strip and crimp cable with various Molex connector pins, you need to use the corresponding Molex crimper. RJ45 crimper comes with different specifications too based on the different types of cables. For Ethernet cables, you have to choose the Ethernet crimper that is dedicated to twisted pair cables. Otherwise, it can do nothing at all.

Don’t mix up with BNC crimp tool

The same is true to other connectors like BNC. For example, if you would like to connect cables to BNC connectors, you have to use the dedicated BNC crimp tool instead of the RJ45 crimpers.

Don’t mix up with RJ11 crimping tool

And another type that is easily mixed is RJ11 crimping tool. RJ45 connector is usually used for Ethernet cable connection while RJ11 connector is usually used for telephone wire connection. So if you buy a RJ11 crimper, what you can do is crimping for RJ11 connector, which can not fit into RJ45 coupler.

Even when it is used for RJ45 cable, you have to make sure its different types too. For example, for EZ RJ45 plug connectors, the dedicated EZ RJ45 crimp tools are required.

Choose RJ45 crimper based on your need

In addition to wire crimper with single function, there are many other crimping tools that come with multiple functions, which are used to secure the connectors to not only Ethernet cable but also telephone wire. On the top of this kind of cat5 crimper is grooves, which comes with three types – 6P, 8P and 4P. The middle one is the most commonly used grooves for Ethernet cable connector while next to them are the grooves for telephone wire connector. On the back of 8P grooves, you can find the dentate module, which is mainly used to secure the eight contacts to the Ethernet cables. For the details about it, please refers to RJ45 pinout.

The first cutting edge of this wire crimper is for stripping. When it closes there should be a gap about 1.5mm. The second cutting edge, which has no any gap, is used for cutting the RJ45 cable. In the middle the space in convex shape is used to crimp the connectors. You can give it a shot to plug an Ethernet connector and look at it whether or not its eight pins align accurately with those copper contacts. At this time please don’t press hard, or a connector would be damaged.

Prices of RJ45 crimp tool

You may find that in the market average RJ45 crimping tools cost less than $10. And some of medium duty cost from $10 to $50. Or if you would like, you can also choose those high-end models that cost more than $100. In fact their functions are quite similar and so do their methods of operation. The difference between them is the brands and the quality. Usually those of low price don’t necessarily mean that they are of low quality. In terms of which one should be chosen, it really depends on your budget. Compared to those average ones, certainly the RJ45 crimper of famous brand tends to give you some extra reassuring.
