How to Choose the Right Contacts for Your Connector?

Contacts exist in various sizes and varieties, making it difficult to choose the right ones for your connectors. This information will help you decide which product will provide the optimal connection for your needs at the lowest cost.

Electrical contacts

The two most common forms of electrical contacts are:

Signal

Electrical signals can communicate information from one location, source to another or destination. Most cases, a huge amount of information will be referred to as data because of the quantity involved. On the other hand, signals often carry essential information in binary form (for example, ON or OFF), and they can be found in applications such as sensors or buttons. Signal contacts are typically relatively modest (#20 and #16) since they do not need to transfer a significant amount of current or voltage (usually between a few mA to a few A).

Power

Power contacts, on the other hand, are responsible for transmitting voltage and current to make components and machinery operational. When it comes to applications that only need low voltages, the contacts might be the same as the signal contacts. However, larger applications or those that use a lot of energy will require larger contacts, such as size #12 or size #8. A few dozen Amps of current can be delivered using industrial power contacts.

Criteria for Selecting Contacts

Now that we have a better understanding of what contacts are let’s look at how to select the pair that will work best for you. Before you make your decision, there are a few factors that you need to take into consideration.

Connectors and the layout of the (to determine contact size)

• Your wire size
• Contact type (machined, stamped & formed)
• Delivery option (bulk or on a reel)
• Plating
• Termination type (crimp, solder, PC tail, wire wrap)

Specs

The amperage and voltage that will be traveling through your circuit should be taken into account as the very first factor when choosing connections. This will decide the available connectors and, as a result, the contact sizes.

Don’t forget to consider your connector’s and contacts’ ability to carry current. The contacts in your connector will generate heat as electrical current flows through it, and the more contacts you have, the more heat the connector will experience. This means that if your connection’s maximum operating temperature is 125°C and it is going into a machine where the temperature will reach 120°C, the heat generated by the contacts may cause the connector to reach a temperature above 125°C, which could harm your system.

Therefore, choosing the connector layout will be a crucial step. Because adding more contacts within your connector will produce more heat for contacts of the same size and capacity, it is essential to strike the right balance between your electrical needs and the connection’s ability to transmit current. If you choose your layout first, it will define which contact sizes can fit. Each design is also created for specific contact sizes.

Wire Size

This component is most likely the easiest to understand. The wires that will be placed into the connector are generally already there if you are going to purchase contacts. You can choose from various contact sizes depending on the size of these wires.

On the other hand, AWG wire sizes 8, and 10 (8.36 mm2 and 5.26 mm2, respectively) can only have #8 connections since all the other contacts are too tiny.

Contact Type

In addition to machined contacts, other types of connections include stamped and molded contacts. This decision will largely be guided by your taste and the crimping equipment at your disposal.

Machined contacts are typically favored for use in power applications and low-volume order placement. They usually have a higher load-bearing capacity and are designed to withstand rigorous use. Contacts stamped or molded have the advantage of being fed into automated crimping equipment, making them more suitable for big-volume production.

The norms require machined contacts of some industries, most notably the aerospace and railway industries.

Delivery Options

There are a few different ways that contacts can be provided; for example, they can be placed onto a reel, or they can be delivered loose in bags. Although all choices are available, stamped and formed contacts will be provided on reels by default, while machined contacts will be shown in bulk and wrapped loosely.

What you decide to do here will mainly be determined by the configuration of your system. Depending on the automated or semi-automatic crimping equipment you use, you might be required to get your contacts in one of these options. Remember that stamped and formed references mounted on reels are usually meant to be fed into automatic crimping machines. Any attempts to crimp these contacts using hand tools may result in quality problems.

Plating

The plating affects the contacts’ conductivity and lifespan. Under 1A and 5mV, more minor contacts (#20 and #16) will have at least 0.4 mm of gold plated on them. Since gold has good lubricity and conductivity, it can withstand repeated mating cycles and heavy use. However, it does have one drawback, namely a hefty price.

A larger surface results in a greater plating cost for marginally larger contacts; this explains why tin, a less expensive choice that functions almost as well in static or low-vibration conditions, is typically found. The option of gold flash plating is suggested to create a more dependable connection for applications where the system will be subject to greater vibration or multiple mating cycles (100+).

Silver is the recommended material for contacts in sizes #12 and #8, as it offers the ideal compromise between price and good reliability.
