![]() In addition to the three general categories of electrical power connectors, there are numerous individual connectors that fall under each heading. Because of the large load they can carry, heavy-duty connectors are effective in large-scale power distribution applications, as well as power management and protection systems, such as circuit breakers. Heavy-duty connectors carry high-level currents in the range of hundreds of kilovolts (kV). Medium-duty can be found in an array of domestic and industrial applications. Thus, proper material selection is critical in ensuring the device’s integrity. Unlike low-duty connectors, medium duty variants can suffer from electrical wear if the contact material isn’t carefully monitored to prevent involuntary welding and erosion. Medium Duty Electrical Power ConnectorsĪ medium-duty power connector carries a higher-level electrical current at up to 1,000 V. Power connectors found in cars, radio and communication devices, and those intended for basic instruments are all classified as light-duty power connectors. It’s important to minimize the presence of external contaminants on connector contacts (such as dirt, dust, and water) because the component is prone to oxidation and contaminants can catalyze the process. However, if contact resistance doesn’t stay low and stable, the ability of the device to transmit current may be compromised. Light Duty Electrical Power ConnectorsĪ light-duty electrical power connector can carry up to 250 volts (V) of a low current. Generally, electrical power connectors are classified according to how much voltage they carry. There are three categories of electrical connectors: light duty, medium duty, and heavy duty. Each category heading refers to how much voltage the connector can handle. To better understand which connector is best-suited for a particular purpose, it’s helpful to examine how electrical power connectors are classified and the capabilities of each variant. Depending on the electrical current carried and the purpose of the application, one of several types of power connectors may be appropriate. Depending on the amount of current and type of cable or wire, different connectors are used.Įlectrical power sources can range in size from small batteries to large power grids, therefore, connectors that allow the transmission of electricity vary in form. In electronics, electrical power connectors are what you plug into a device’s receptacle. Electrical power connectors are the link between a device and its source of power. ![]() When it comes to electronics, power is essential.
