Terminals and Connectors
What do we mean by terminals and connectors?
Terminals and connectors are any of the various types of electrical wire connectors used to end a wire or cable and connect it to an electrical system or terminate it completely. They can be anything from ring terminals, butt splices, wire caps, ferrules, fork terminals, pin terminals or a host of other styles which are available in a variety of insulation styles. Pacer Group carries everything from waterproof connectors to battery posts and everything between. When selecting wire terminals, you need, the first thing to do is consider what requirements you’re looking for. Do you need waterproof terminals? Is vibration resistance important? What kind of temperatures will the wire terminals need to handle? Questions like these will help you isolate the type and style of wire connector to crimp that will work best for your particular application.

What types do we offer?
We understand that no two jobs are alike and as such, a variety of parts and tools are needed to give the best possible solution. That is why Pacer Group carries a range of wire terminals and connectors. This way you find what you need when you need it. Each type of terminal or connector we carry is something we feel people need access to. Many sites will carry one or two types of electrical wire connectors but are they really offering solutions or just trying to make a sale? By carrying more than we need to, we are offering the greatest number of solutions and ensuring that you find what you need. Take a look below at some of the more popular styles we carry.
These connectors are designed for use where cable-to-cable circuits need to handle harsh conditions. One major advantage of environmentally sealed connectors is that they are field serviceable. No need to cut, strip and re-terminate wires in order to repair a connection. With these connectors, you simply disengage the locking mechanism, pull them apart, make your changes, and reconnect them. It really is that simple. This is one of many reasons you’ll find these in industrial applications.

This type of connector is used to safely connect one or more wires to another wire. There are a variety of styles depending on what the task at hand is. If you simply need to replace a section of wire, a regular butt splice will work. In some cases, you may need to connect two smaller gauge wires to a larger one. In that situation, you would want to use step-down butt splices. Utilizing butt splices reduces the number of wire connectors to crimp. Remember, pay attention to the conditions your connection will need to endure and use that to help select the right type of insulation for your project.

are the most secure type of tongue style wire terminals. That fit cleanly over a stud and are held in place by the locking nut. The advantage of ring terminals is that they remove the possibility of terminal slippage you may find with other types of terminals. These are a common choice due to their durability and ease of installation. They are easy wire connectors to crimp. Depending on the application, you can connect multiple wires to a single ring terminal or connect multiple ring terminals to a single stud.
|Insulation Styles||Type of Terminal||Wire Gauge|
|Non-Insulated||Ring Terminal||Twenty-Two Gauge - Ten Gauge (22AWG - 10AWG)|
|Nylon||Ring Terminal||Twenty-Two Gauge - Ten Gauge (22AWG - 10AWG)|
|Vinyl||Ring Terminal||Twenty-Two Gauge - Ten Gauge (22AWG - 10AWG)|
|Heat Shrink||Ring Terminal||Twenty-Two Gauge - Ten Gauge (22AWG - 10AWG)|
We carry these types of wire terminals in two options, locking and flanged. These are a useful type of electrical wire connectors in environments where you may need to make adjustments without having to fully remove a screw. When using forks to connect one or more wires to a stud, you want to be confident that it will not come loose. Commonly in an electrical environment, vibration can loosen holding screws. To combat this, we recommend flanged forks which snap around the stud creating a solid connection or locking forks which grip the nut also creating a solid connection. This way you know that you've created a solid connection that will not come loose.
|Insulation Styles||Type of Terminal||Wire Gauge|
|Non-Insulated||Fork Terminal||Twenty-Two Gauge - Ten Gauge (22AWG - 10AWG)|
|Nylon||Fork Terminal||Twenty-Two Gauge - Ten Gauge (22AWG - 10AWG)|
|Vinyl||Fork Terminal||Twenty-Two Gauge - Ten Gauge (22AWG - 10AWG)|

These wire terminals are designed for use where the electrical connection is intended to be connected and disconnected multiple times. This is why disconnects are a preferred choice when it comes to field serviceability. They offer superior holding force due to the indentation of the tab of the female part locking into the hole in the male part. This type of connector is known for being simple wire connectors to crimp. Their ease of use makes them a solid choice. Even though they are built for disconnection and reconnection, they are equally built for permanent placement. If you plan to leave them on as a permanent option choose the insulation type that best supports the environment where you will be placing them.

are commonly found in use with compression type terminal blocks. What this means is that many terminals blocks use screws to hold a wire in place. The issue is the many people have to deal with an electrical system that uses stranded wire not solid. When you tighten a screw down on a group of tiny wires, the individual wires become frayed or weakened. This can lead to long term issues. The solution is to use a pin terminal in order to consolidate the wires into the equivalent of a solid wire. These are an effective choice when it comes to electrical wire connectors. Now when the screw tightens, the force is applied equally, and damage is avoided.

are similar to ring terminals in that they connect to a stud through a circular opening. Lugs, however, are much more durable and are usually meant for either larger gauge wire and cable or for harsh environments where corrosion is an increased risk. These are high-quality, durable electrical wire connectors. Think about it, you wouldn’t use a ring terminal to connect a car battery. You would use something specifically meant to handle a tough environment. When considering wire connectors to crimp, always factor the level of protection needed. In order to be as effective as possible, lugs need to be tough and conductive. That’s why all the lugs we carry are made from high quality copper for the highest level of conductivity.

vary in their design much more than most other types of wire terminals. You have everything from snap-in connectors to twist-on electrical wire connectors and even some that require soldering. That’s due to the fact that coaxial connectors are used in a wide range of applications. This means that they need to be versatile to meet a range of needs. They are used in everything from radio transmissions and digital broadcasting to even microwave industries. These are specialized wire connectors to crimp and may require specialized tools. Before selecting the connector you need, make sure to be aware of the specific usage and the type of mating the connector will need to offer.

|BNC Series||Coaxial Connector||RG58, RG59, RG62|
|PL259 Reducer Connectors||Coaxial Connector||RG58, RG59, RG62, RG8X, LMR-240|
These connectors are used to create a permanent seal. That means that they have to be built with durability and longevity in mind. Compression seal connectors are used with coaxial cables, but their installation process is vastly different. Compression tools are used on these wire connectors to crimp them correctly which guarantees the permanent seal mentioned above. This keeps the electrical wire connectors from ever coming off or being pulled out. All Pacer Group compression seal connectors are made from machined annealed brass and coated with an anti-corrosion nickel plated finish.

This type of electrical wire connectors are used to connect a load to a battery. In order to give the highest level of conductivity, all Pacer Group battery posts are made from 131 contact copper. We use this type of copper as it is 95% pure making it highly conductive. Specialized tools may be needed to work with these wire connectors to crimp them correctly. One issue that plagues a lot of battery posts is that they can get corroded over time with causes a range of problems. To prevent this, each post is electro-plated with a bright tin finish. For an added layer of protection, you can add a boot covering to your post. This will help to extend the life of the connection.

When you work with terminal blocks, using the non-terminated end of stranded wires as a connection point will lead to fraying and weakening of the connection. You want to consolidate your stranded wires into one singular point of connection. This is where wire ferrules come in. They create a superior connection to a terminal block. By consolidating the wires into the ferrule, you minimize your risks of the connection fraying or coming loose. This, in turn, creates a stronger connection. These are simple wire connectors to crimp given you have the proper tools. When considering wire connectors to crimp, always factor the tools required.

What types of insulation are available?
The insulation wire terminals carry has a significant effect on the environments they can handle and their overall longevity. Pacer Group carries many wire terminals in four insulation options; heat shrink, nylon, vinyl and non-insulated. This way you can get the wire terminals you want in the insulation you need. Heat shrink offers a range of advantages which is why it is a popular choice. For starters, epoxy lined heat shrink creates a moisture-proof barrier that will prevent corrosion from damaging your conductors. This is especially important in marine environments. Heat shrink terminals also offer more flexibility and abrasion resistance meaning that will last longer than other styles in most conditions. Another benefit of heat shrink terminals is that they are translucent. This means you can easily visually inspect your crimp to make sure the connection is strong. Nylon terminals, in many cases, are can be double crimped. This is where the crimp on the wire is strengthened by a secondary crimp on the insulation. This gives the connection a stronger hold and longer life. Nylon terminals are semi-translucent which means that visual inspection of the crimp can verify the connection. Vinyl terminals are the most cost-effective insulated option. They are available in a wide range of styles and are a very common choice when looking at wire connectors to crimp. Non-insulated terminals are the least expensive, however, they offer the least amount of protection. One strong point of non-insulated is that the crimp is easy to inspect. In certain circumstances, solder can be added to strengthen the connection and create a better seal. All our electrical wire connectors are built with durability in mind.
