Connector Material

Conductor and insulating materials make up electronic or electrical connections. Although you may use other materials, plastic and metal are the most frequent materials utilized to build connections. Because the conducting material affects the mechanical durability, electrical conductivity, resilience, and formability of the electrical connections, it is significant.

Typical terminal materials that are available for usage include:


In terms of weight, brass is the least expensive metal you can employ. Generally speaking, depending on the use, brass’s zinc concentration might range from 5% to 40%. Brass has sufficient electrical qualities, strong spring strength, and significant strength.

For KK terminals, brass connectors are often utilized.

Bronze Phosphor

Compared to brass, phosphor bronze is stronger and more resilient. It has improved fatigue resistance and remarkable conductivity. Because of its exceptional flexibility, phosphor bronze may also be used in electrical contact springs.

Copper Beryllium

The ideal copper alloy for spring terminals is beryllium copper. Beryllium makes from 0.5% to 3% of the mixture together with other elements. Compared to phosphor bronze, the alloy is less expensive and has a higher strength.

High Copper Alloy

High copper alloys are appropriate for demanding applications because they have a high copper content (above 96%). The alloys offer superior thermal and electrical characteristics in addition to their great strength. Since they don’t soften readily, you may even use them in high-temperature environments.

Automotive applications are the main usage for high copper alloys.

We shall discuss the factors to take into account while selecting electronic connections in the upcoming chapter.

A Factor to Take Into Account When Buying Electrical Connector

Selecting the best connection for your application requires careful consideration of a number of aspects. There are many different kinds of connections on the market, so be sure to select carefully. Here are some things to think about:


For many engineers and manufacturers, cost is typically a crucial factor. You do want to get the finest for the least amount of money, after all.

If achieving that is your aim, avoid selecting your connections only on the basis of price. It’s possible that you’ll get subpar goods that won’t work and will make your project fail.

To get the most cost-effectiveness, constantly prioritize quality and strive to find a balance between costs.

Additionally important is the setting in which you want to use the connections. Are the connections going to be utilized in the water or on dry land? or on a boat? Will there be severe weather that affects the connectors? Will there be shocks and vibrations during the project?

Based on your usage environment, choose the appropriate connections. When choosing connections, consider those with environmental sealing for protection against flammable gases, liquids, vapors, and dust.

Select the connections after deciding on the required level of safety. When choosing, bear in mind the working temperature range as well.

Signal Sort

The signal that each connector transmits will determine which connectors you need to use. Signals might be digital, analog, or a mix of the two. What frequency, if any, is there in the analog signal? Does it make use of RF or audio? For analog transmissions, what is the bit rate or clock speed?

The kind of connection, pinout, and wiring you require depend on the type of signal.

Keep in mind that some signal combinations cannot be used on the same connection. For high-voltage pins, clearance distances and creepage must be taken into account. On the basis of your own requirements and design criteria, you may also choose a bespoke solution.

Level of Power

Your decision will also be influenced by the amount of current flowing through your connection. You will need numerous bigger, thicker pins for high current routes. Select a connection with greater insulation if you are working with high voltage. You might also need to take creepage and clearance distances into account for high voltage pins.

Wire connection – Sturdiness

The strength of the connections you need depends on the frequency of your terminals. Will you be plugging in and unplugging the terminal frequently? Consider your application while selecting a tough connection.


For every electronic device to operate well, the electrical connector is essential. Selecting dependable and high-quality terminals that guarantee the success of your project is always a smart move. To learn more about electrical connectors and customized solutions, contact us right now.
