USB Type-B Female Connector 4-Pin USB 2.0 PCB Mount Socket
The USB Type-B Female Connector, also known as the Standard USB Type-B Receptacle, is one of the most widely used USB connectors in embedded electronics, computer peripherals, and industrial equipment. Designed for dependable power and data connectivity, this connector is commonly found in printers, scanners, Arduino development boards, CNC controllers, communication devices, and various USB-enabled embedded systems.
The USB Type-B connector features a distinctive square-shaped design with beveled upper corners, ensuring proper orientation during insertion. It provides a secure and reliable connection between USB host devices and peripherals while supporting both 5V power supply and USB 2.0 high-speed data transfer.
This connector includes 4 connection pins with 0.1-inch (2.54 mm) spacing, allowing convenient installation on development boards, prototype boards, and custom PCBs. The support posts provide additional mechanical strength during repeated plug insertion and removal. For applications requiring greater flexibility, the support posts can be accommodated by drilling holes in the PCB or removed if necessary.
The USB Type-B Female Connector is widely used in Arduino Uno and Arduino Mega boards as the primary USB programming and power interface. It is equally suitable for DIY electronics, embedded system development, USB communication projects, firmware programming, debugging, and industrial automation equipment.
Manufactured with durable insulating material and high-quality metal contacts, the connector provides excellent electrical conductivity, mechanical stability, and long service life. It complies with the physical and electrical requirements of the USB 2.0 standard, ensuring compatibility with standard USB Type-B cables and host devices.
Whether you’re designing a new development board, replacing a damaged USB connector, repairing an electronic device, or building a custom USB interface, the USB Type-B Female Connector offers a reliable and cost-effective solution for USB power and communication.
