Read on to find out more about standard circular connectors.

What are standard circular connectors?

As with other types of circular connector, a standard circular connector is a cylindrical electrical connector. It features multiple pins and contacts that are surrounded by the housing. When the pins are connected to the housing, the connection is complete, and this continues the circuit in electrical devices. These connectors can also be used to transmit data or signals, which means they are suitable for a number of settings.

The casing tends to be made of plastic, although metal models are also available. Some of these round connectors feature a combination of the two materials.

Why choose a standard circular connector?

Standard circular connectors offer plenty of benefits for those researching ways to complete a circuit or transmit information. The main one is that they are a dependable choice. The rounded structure allows several contacts to be gathered in one place, making it a useful space-saving tool for connecting cables from devices.

These connectors also make it easy to allow contacts with a range of currents. This is because they can withstand a range of voltages.

Additionally, of all the options on the market, standard circular connectors are possibly the most robust, thanks to their shape. These models benefit from being free of angles as they can be safely stored without causing damage. In addition, they pose less of a hazard than their rectangular counterparts as they neatly fit against walls and in cabinets.

What are circular connectors used for?

As they are so versatile, these round connectors have a range of applications. As well as industrial settings, they can be found in industries such as aerospace, defense and security, along with the energy and medical sectors. Their shape and the robust housing for the contacts makes them resistant to turbulence and forceful impact.

What are the different features of standard circular connectors?

There are different types of circular connectors, each designed to perform a certain function. Standard circular connectors typically conform to American or German military standards.

There are different features to factor in when choosing your connector. One of the main functions to decide between is the 4-pin or 6-pin circular connector. From there, you can then browse the models available at RS.
