USB 2.0 Type B Female Connector

The USB 2.0 Type B Female connector is a square-shaped port commonly found on larger peripheral devices like printers, scanners, and external hard drives. It is designed to mate with a standard USB Type B Male plug, forming a stable and secure connection for data transfer and power delivery. This robust port supports the USB 2.0 specification, offering speeds up to 480 Mbps. Its distinct shape prevents incorrect insertion, ensuring a reliable link between the host computer and the peripheral device.

Product Feature

The USB 2.0 Type B Female connector is a standardized peripheral port renowned for its specific physical and electrical characteristics. Here are its key features:

Robust Physical Design:

Characterized by its square shape with a slight taper and a prominent notch on top, the connector measures approximately 10.44 mm x 8.00 mm. This design prevents incorrect insertion and provides greater physical stability compared to Type A, making it ideal for frequently handled devices like printers and scanners.

4-Pin Configuration:

The interface features a 4-pin layout (VBUS, D-, D+, GND) that handles both power delivery and differential data signaling. This pinout is crucial for the half-duplex communication protocol defined by the USB 2.0 specification, supporting the 480 Mbps High-Speed data rate.

Dedicated Peripheral Use:

Unlike the host-oriented Type A, the Type B female port is exclusively implemented on peripheral devices. This clear host-to-peripheral distinction prevents incorrect connection topologies and ensures a master/slave relationship within the USB network.

Moderate Power Delivery:

The connector supplies a standard 5V DC power at up to 500 mA (2.5W) per port as defined by the USB 2.0 Battery Charging Specification. This is sufficient for powering a wide range of bus-powered peripherals without an external power source.

Durability and Retention:

Designed for frequent mating cycles, the connector typically withstands 1,500 insertion/removal cycles. The square form factor and firm fit provide excellent mechanical retention, minimizing disconnection due to cable strain in office and industrial environments.

Clear Host-Peripheral Distinction: 

Its physical design is intentionally non-interchangeable with Type A connectors, enforcing a unambiguous host-to-device connection path. This eliminates potential network conflicts and simplifies the user connection process.

Application field

The USB 2.0 Type B Female connector is a cornerstone of connectivity in numerous professional and industrial settings.

Professional Audio/Video Equipment:

It is the standard port on audio interfaces, mixing consoles, and video switchers, providing a stable and reliable connection for data transfer and device control.

Printing & Scanning:

Nearly all desktop printers and high-end scanners feature this robust port, ensuring a dependable link to a computer for handling large print jobs and high-resolution image data.

External Storage Solutions:

Many external hard drive enclosures and network-attached storage (NAS) devices utilize this port for its durability and consistent performance in data-intensive backup and retrieval tasks.

Industrial Control Systems:

Its sturdy design makes it ideal for factory automation, programmable logic controllers (PLCs), and test & measurement equipment where a secure, latching connection is paramount.

Legacy Peripheral Connectivity:

It serves as a critical interface for older yet vital peripherals, allowing them to remain functional in modern computer setups through adapter cables.
