Frequently Asked Questions

What are crimp connectors?

What are crimp connectors?

Crimp connectors are a form of solderless electrical connector that is used to terminate stranded wire. Crimp connectors are also known as crimp terminals. Crimp terminals, commonly known as crimp connections, are quick-disconnect devices with spade-foot connectors. Wire splices, and screw terminals, depending on the crimp connector.

Using a wire stripper to remove the electrical insulation from the end of the stranded wire is the first stage of attaching a crimp connection. After this step, the connector can be attached. Since this is reasonably typical for home electrical wiring, it is usual to see three-quarters of an inch (3/4) as a general guideline for how much wire to strip. However, the length of insulation that needs to be removed is genuinely application-specific and should be cross-referenced with the manufacturer’s standards, mainly when the insulation is being used in an industrial setting.

After the insulation has been stripped away, the bare wire is put back into the connector where it belongs. Afterward, a set of crimping pliers squeezes the crimp tightly around the wire to secure it. If the joint is finished properly, it will be gas-tight and provide mechanical stability.

There are many variations of crimp connectors, but the barrel and open barrel varieties are the most prevalent ones. When working with barrel-type connectors, stranded wire is first crimped after being put into the connector’s cylindrical metal opening (thus the name “barrel”). This type of connector is perhaps the one that is used the most frequently.

Open barrel connections are also accurately titled as the “barrel” is split into a V or a U shape. This gives the connectors their distinctive appearance. After the wire has been cradled into the connector, the connector will next be crimped shut. In contrast to barrel connections, which need the wire to be threaded into the connector, this connector allows the wire to be simply put into the connector, making its use in automated applications much simpler. In most cases, these connections’ strength surpasses those produced by barrel connectors. Because of their durability and user-friendliness, they are frequently used in various industrial and automotive applications.

Crimped and soldered connections have their benefits and drawbacks, which are the subject of much discussion. In addition to the task, the particular size and kind of wire play a significant role in determining which connection makes the most sense.

What is a SUPERSEAL 1.0 connector?

Environmentally sealed SUPERSEAL 1.0 connectors are offered in various forms, including cable plugs and PCB mount headers. In applications in severe environments, SUPERSEAL 1.0 connections are utilized since even a slight decrease in connection can have a significant impact.

When should I use SUPERSEAL 1.0 connectors?

The durability and performance of SUPERSEAL 1.0 connectors can be utilized in various locations, including the engine or gearbox, under the hood, for motor controllers, on the chassis, in the cab, and more. The reliability and rugged qualities of SUPERSEAL 1.0 connections have been demonstrated in the field.

Connectors with the SUPERSEAL 1.0 designation were developed to address the growing demand for reliable printed circuit board applications to be used in hostile situations. The SUPERSEAL 1.0 headers come with either straight or right-angle pins, depending on your preference. There are many different alternatives for locking latches and keying systems available.

What are the types of standard Electrical Contacts?


Electrical signals can communicate information from one location, source to another or destination. People typically refer to such information as data when referring to a huge amount of information. 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. As a result, signal connections are often relatively modest (20 and 16), as they do not need to transfer a significant amount of current or voltage (usually between a few mA to a few A).


On the other side, power contacts are responsible for transferring voltage and current to make components and machinery function. The connections can be the same as those used for the signal in applications that need low voltages. However, larger applications or those that use a lot of energy will require larger contact sizes, such as size 12 or 8. A current of up to a few dozen Amps can be delivered by power connectors used in industrial settings.
