How To Choose The Right Power Connector For Our Business Needs

0

Power connectors are also said to be chargers, power supplies, and AC adaptors. The electronic devices that we utilize in converting AC power from wall outlet to usable DC voltage are said to be power adapters and the plugs that are used to connect the electronic devices with adaptors are known as power connectors.

Power connectors are easily available in the market at a very low cost. They are completely fulfilling our business needs. When a person wants to start a new electronic project then he has to consider all the requirements needed in building that particular project. Choosing the right power connector is one of the important topics that must be discussed before starting a new electronic project. 

Nowadays, we can easily find inexpensive connectors. Many people find it difficult to choose the right power connector so this article is totally for such people. In this article, we will know how a person can choose the right power connector and some requirements that a person must have to consider before choosing the right power connector.

Choosing the correct power connector

Before buying any power connector we must have to choose power connected based on:

  • Size.
  • Polarity.

Below is the explanation of choosing a power connector based on size and polarity.

Based on Size

While choosing the size of the power connector, we must consider two measurements to specify the size of the power connector. These are:

  • Plug-OD
  • Plug-ID

Plug-OD describes the outer diameter of the power connector and plug-ID describes the inner diameter of the power connector. Connectors labeled as ‘2.1mm DC connectors’ are the most commonly available connectors in the market. Such connectors have a 5.5mm diameter and a 2.1mm center pin. Single adaptors having a 2.1 plug works very amazingly. 

  • Plug Size:
  • Other connectors can have the following plug size:
  • 8mm x 1.7mm
  • 5mm x 1.7mm
  • 5mm x 2.5mm
  • 5mm x 2.1mm
  • 3mm x 3.0mm

Hence we can easily find the size of a power connector by measuring the OD (inner diameter of port) and ID  (diameter of the center pin). The OD and ID measurements must be matched for the connection of female and male DC connectors.

Based on Polarity

After choosing the size of the power connector, we must match the polarity also for a reliable connection. The circular connector is within almost every appliance. In such types of connectors, one pole is carried by the inner hole and the other pole is carried by the outer hole.

We can easily find the center-positive types of connectors but we can also find the center negative types of connectors. Hence while selecting a power adapter, we must remember that the connector matches with our electronic device.

Choosing Universal Power Connector

Universal power connector proves to be a great choice when we are not sure about the size or polarity of the power connector or multiple devices are to be worked in our business. The main advantage of a universal power adaptor is that it allows us to use different connectors, polarities, and voltages.

Conclusion

The above discussion clearly shows that the device used to make a connection between AC adapter and electronics devices is called a DC power connector. The purpose of the Dc power connector is to convert the AC power from the wall outlet to DC voltage so that PC, laptops, and other devices can utilize it. We must make sure that the polarity and size of the power connector are matched for a reliable connection.
