Wire Ferrules
What are wire ferrules?
*This Page was Updated on 2/22/2021.
Wire Ferrules are a type of terminal used on a stranded wire to prevent fraying. Think of them like a barrel that slides over the wires and completely covering them. Commonly, they are used on wires inserted into IEC (European) style terminal blocks. The purpose is to create a better connection to the block. How do they do that? Well, if you tried to connect the wire to the block the connection would be weaker. This is due to the fraying of the stranded wire. As you tightened the screw, it would push into the stranded wires and cause them to separate. Wire ferrules essentially make the end of the stranded wire one solid piece. As we said above, wire ferrules keep the wires from stranding by jacketing the wire. This prevents the wire from fraying and provides a more solid connection.
How do you use a Wire Ferrule?
First, the wire is stripped to the correct length and the ferrule is slid over the exposed wire. The nylon casing at the base of the ferrule should butt up against the insulation of the wire. Next, the wire ferrule is crimped using the proper tool. Proper crimping pressure and technique are key to ensuring continued performance. To enhance the lifespan of the connection, heat shrink can be added for extra protection.
What types of wire ferrules are available?
Wire ferrules are separated by the wire gauges that they handle. In this way, you can find the size you need to handle just about any task. We offer wire ferrules in 24-22 AWG, 22-20 AWG, 20-18 AWG, 18 AWG, 16 AWG, 14 AWG, 12 AWG, 10 AWG, 8 AWG, 6 AWG, 4 AWG, and 2 AWG. Each size of wire ferrule carries a specific insulation color. Take a look at the table below to help gain a better understanding of which wire ferrule is right for your project.
What advantages do they offer?
Wire ferrules offer the advantage of keeping your connections strong when your wire is connected to the terminal block. Not only that, but they also reduce the risk that the wire will pull out. The durable design of wire ferrules ensures that they can not only stand the test of time but that they can handle the toughest environments out there. Wire ferrules are known for their longevity which is just one of the many reasons you will find this type of terminal in use in so many industries.
Where would I use wire ferrules?
Wire ferrules can be used anywhere you are using European terminal blocks or similar applications where you need to prevent wire fraying. That is to say, that they can be used in just about any environment. Often times you will find wire ferrules in use in places like marinas, repair shops, industrial job sites, and even private garages. Since they serve the advantageous purpose of preventing wire fraying, especially when used with terminal blocks, wire ferrules have become known as a versatile and useful product.
What do ferrule boxes include?
Ferrule boxes are convenient packages that contain a variety of wire ferrules in an easily dispensable case. Carrying between 10 to 100 of several different types of wire ferrules, these cases are the ideal solution for field service and on-the-go needs. We currently offer two very different ferrule boxes in order to give you the largest selection possible. Take a look at the chart below to decide which of the boxes has the wire ferrules that you are looking for.
