DC Connectors

DC power connectors, also known as cylindrical connectors or coaxial power connectors are designed to supply DC power to an extra-low voltage device. We offer both waterproof (IP67) and none-waterproof variations. Alongside these, we have combined connectors which include a pushbutton, rocker switch or slide switch. This allows for a smaller footprint than a sperate connector and switch configurations.

Frequently Asked Questions about DC Connectors

DC connectors are also known as coaxial power connectors are sized based on their outer and inner diameters, for instance, sizes such as 6x4mm, 5.5x2.5mm and 4x1.7mm. DC connector are designed so that the larger number is the outer diameter, this would be the outer diameter of the male part or the size of the hole on a female part. While the smaller number relates to the inner diameter, this being the hole on the male part and the diameter of the inner pin on a female connector.

A DC power jack works by passing electricity through its central barrel and using its external barrel as the ground, this set up ensures that you cannot accidentally touch the live part of the connector. The male plug is then pushed into a female jack which is held in place by friction. The live part of the plug is now connected to the central pin within the jack while the outer ground is connected to the inner part of the jack housing completing the circuit.

AC and DC are both electrical currents, they stand for alternating current and direct current. AC power is the standard type of current that you will find in homes and businesses, it is called alternating current as the direction of the charge periodically changes between positive and negative. This is down to the way in which the electricity is created and distributed as AC can travel much further than DC. DC however is a direct current and does not change between a positive and negative state. This form of power is therefore found in batteries and battery-operated products, such as laptops. In these cases, the AC current from the wall outlet is passed through a transformer to change it to DC before it enters your device.
