PJ-202A

Barrel - Power Connectors is a broad field of electrical connectors for connecting one or many wires from a power source to a consumer application. The PJ-202A application field and working principle are just one example of the many power connectors available today.The PJ-202A is a two-pin power connector with a male and female design. The plug has a locking screw, or Barrel, which prevents the wires from becoming detached from the connector. It is used to provide a secure connection for a range of power and communication devices, from computers to power adapters. The plug body is constructed of polyamide and the contact pins are silver-plated copper.The barrel design of the connector makes it easy to use because it is compatible with a wide variety of connectors, including the more common three-pin power connectors. It also has a good contact resistance and can carry up to 10 amps of current. The plug can be used with a variety of sizes of wire ranging from 12 to 24 AWG.The working principle for the PJ-202A is similar to other power connectors. When the plug is inserted into the socket, the two contact pins are in direct contact with the electricity flow. When the locking screw is tightened, the pins are forced into the socket and the metal surface of the Barrel is in contact with the socket, completing the connection. This connection is mainly used to connect a device such as a power adapter to the power source.The PJ-202A is mostly used in the computer industry for its strong connection, good contact resistance, and compatibility with a wide range of connectors. It is also used in a variety of consumer electronics, such as audio devices, cameras, and video game consoles.The PJ-202A is reliable and easy to use. It is cost-effective and can be used in a variety of applications. For these reasons, the PJ-202A is popularly used in both professional and consumer applications. With its two-pin design, the connector is capable of carrying higher loads and has a greater degree of resilience than other connectors.In conclusion, the PJ-202A application field and working principle is a successful example of a Barrel - Power Connectors. It provides a secure connection, is compatible with a wide range of other connectors, and is easy to use. It is cost-effective and reliable, making it the perfect choice for a variety of applications.
