Things to consider when purchasing the best wire connectors in the market

Do you know that choosing the right wire connector for your application can be one of the toughest tasks ever? There are numerous wire connectors in the market. The right wire connector for your needs will provide a reliable means to field maintenance. There are several crucial things you should consider when purchasing the best wire connectors in the market. Here are the most crucial things you should not leave behind when making your purchase.

Current rating

It has emerged as the most important factor you should consider when selecting wire connectors. Usually, the current rating is stated in amps per circuit. In simple terms, the current rating is the amount of current that can be passed through a mated material. It is important to note that the current rating of a certain circuit size will assume all circuits of the housing. Additionally, it assumes that the maximum wire gauge for that connector is used. What if a small wire is used? In that case, the maximum carrying capacity should be dated by 1.0 amps in the circuit.

Connector size and circuit density

It is becoming an important factor in wire connectors selection process. You can agree with me that indeed the downsizing equipment has been trending over the years. What is circuit density? It can simply be described as the number of circuits a wire connector can hold per square inch. With this measure, you will be able to determine the space requirements and the size of one connector family. Most wire connectors in the market provide high current capability and high circuit density with small housings.

Level of reliability

Reliability is another essential factor that needs to be considered when purchasing wire connectors. However, reliability has become a complicated concept that mainly depends on many factors. It is quite a difficult task to determine accurate figures. Fortunately, the most reliable wire connectors come with specification for mean time to failure. The specification is very important since it serves as a guide in selecting the right wire connector for any application.

Environmental sealing

You might have heard that some environments require protection against invasion of flammable gases. Additionally, you will come across some reliable wire connectors that come with environmental sealing options that are quite effective against unexpected splashes. Once you are aware the level of safety required, you can go on to verify the IP rating number in the code system. In that case, you will be able to know whether you are investing in the right wire connector for your needs.

Material and the plating

It is the last factor you should consider since most wire connectors in the market are manufactured with nylon plastic material. For high resistance, these wire connectors come with inflammability ratings. The most common options in the market include tin, lead and gold.

Calculate the pricing

How should you calculate the price of the wire connector? The price is calculated based on the total cost that includes the plug, the cost of terminal connectors and the labor cost.

Check the operating temperature range

Nowadays, most wire connectors are subjected to extreme and harsh conditions that include vibration and shock. Wire connectors and terminal connectors manufactured to be used in harsh conditions come with unique features that enable them to resist vibration and shocks. They can also resist extremely high temperature.

Wire size

It is a crucial criterion when looking for the best wire connectors. Kindly don’t forget this factor more so when the current rating required is near the maximum. The best wire connectors in the market can accommodate wire gauges of 16 AWG.

The criterion that matters most to you will dictate the size and the model of your wire connector.


Presence of the warranty in the wire connectors kit allows you to return the product in case you are not satisfied with it. You should avoid wire connectors that don’t have a warranty. Usually, reputable manufacturers specify the warranty of the specific product.

Final thoughts

Pricing, wire size, and warranty are the most important factors to consider when purchasing the best wire connectors in the market. Additionally, you should not forget the level of reliability and the material of the specific wire connectors. And now that we have reviewed the best wire connectors in the market, you will have an easy time when choosing your dream wire connector. We hope that this information will help you in the future.
