The supplied specifications do not provide details such as power-input requirements, individual port power output, dimensions, operating temperature range, or the exact functionality of the switch. These details should be confirmed from the manufacturer’s technical documentation when needed.

5Gbps USB 3.0 Data Speed
One of the primary benefits of the B-04 is its stated 5Gbps data speed.
USB 3.0 is designed for high-speed data communication, making the B-04 suitable for applications where connected USB devices need more bandwidth than older USB standards provide.
Potential devices can include:
- USB storage devices
- External drives
- Flash drives
- USB adapters
- Cameras
- Data-transfer peripherals
- Compatible industrial equipment
The 5Gbps figure represents the stated maximum interface data rate. It should not be interpreted as a guaranteed file-transfer speed in every real-world situation.
Actual performance can vary depending on the host system, connected device, USB cable, storage hardware, software, file sizes, and other components involved in the transfer.
Fully Compliant with USB 3.0 Specifications
The B-04 is specified as fully compliant with USB 3.0 specifications.
This makes it appropriate for users who specifically require USB 3.0 connectivity and compatibility.
USB 3.0 can provide substantially higher data-transfer capability than USB 2.0. However, the connected device also needs to support the relevant USB standard to take advantage of higher performance.
For example, connecting a USB 2.0 peripheral to the B-04 does not turn that peripheral into a USB 3.0 device. Its performance remains limited by the capabilities of the device itself.
Similarly, suitable USB 3.0 cables should be used when high-speed data transfer is required.

Four Additional USB High Speed Ports
The B-04 adds four additional USB High Speed ports.
This configuration can be useful when a system needs several extra USB connections without requiring a very large multi-port hub.
Users may connect compatible peripherals such as storage devices, cameras, adapters, input devices, and other USB equipment.
Four ports can provide a practical balance between connectivity expansion and installation size, particularly for professional workstations and fixed equipment.
Current Protection Throughout
The B-04 includes current protection throughout.
Protection is an important consideration in professional USB installations because multiple connected peripherals can have different electrical characteristics and operating requirements.
The current-protection feature provides an additional protective mechanism within the hub’s design.
However, it should not be interpreted as protection against every possible electrical problem. Users should still follow the manufacturer’s installation instructions and use compatible equipment and cables.
Industrial-Grade Rugged Metal Enclosure
The B-04 features an industrial-grade rugged metal enclosure design.
A rugged enclosure is particularly useful when USB connectivity is required in environments where equipment may be permanently installed or exposed to more demanding working conditions than a typical desktop setup.
The metal housing complements the hub’s mounting options and helps create a more secure installation.
Rather than simply sitting loose on a desk, the B-04 can be integrated into a fixed equipment arrangement using an appropriate mounting method.

DIN Rail Mounting
The B-04 supports DIN rail mounting, making it suitable for installations where DIN rail equipment is already used.
DIN rail mounting can help keep equipment securely positioned inside suitable control cabinets, technical enclosures, or other professional installations.
Potential benefits include:
- Secure equipment placement
- Organized installation
- Reduced surface-space requirements
- Easier integration with other mounted equipment
- Convenient access to USB connections
Before installation, users should confirm that the available DIN rail arrangement and mounting hardware are appropriate for the B-04.
Wall and Surface Mounting
In addition to DIN rail mounting, the B-04 supports wall and surface mounting.
This provides flexibility when the installation environment does not use a DIN rail.
For example, a technical workstation may use surface mounting, while a wall-mounted equipment arrangement may benefit from wall installation.
Multiple mounting choices allow users to select the configuration that best fits the available space and equipment layout.
USB Hub with Switch
The product name identifies the B-04 as a USB 3.0 HUB with Switch.
The supplied specifications do not explain the exact electrical or operational function of the switch. Therefore, the switch should not be described as a specific power switch, port switch, or data switch without manufacturer confirmation.
For product buyers, this is an important detail to verify if the switch function is a key purchasing requirement.

Industrial USB 3.0 Connectivity
Industrial USB connectivity often requires more than simply adding extra ports.
In fixed technical environments, users may need:
- Secure mounting
- Durable enclosure construction
- High-speed USB communication
- Electrical protection
- Organized installation
The B-04 combines these characteristics in one compact four-port hub.
Its rugged metal enclosure and mounting flexibility can make it more suitable for professional installations than a basic consumer desktop hub.
Applications of the B-04
Industrial Workstations
Industrial workstations may require USB connections for peripherals, storage devices, adapters, and other equipment.
The B-04 can provide four additional USB 3.0 ports in a mountable format.
Technical Workstations
Engineers and technicians often use multiple USB devices during testing, configuration, maintenance, and data-management activities.
The B-04 can expand available USB connectivity without requiring a larger multi-port hub.
IT Environments

Best Practices for USB 3.0 Installations
Use suitable USB 3.0 cables: The quality and specification of the cable can affect high-speed data performance.
Match device capabilities: A USB 3.0 hub cannot increase the native capability of a USB 2.0 or older device.
Keep cables organized: Proper cable routing reduces accidental disconnections and makes maintenance easier.
Use secure mounting: Select the mounting option that best matches the installation environment.
Avoid unnecessary cable stress: Even with a rugged metal enclosure, USB connectors should not be subjected to excessive pulling or bending.
Follow installation requirements: Current protection is an additional protective feature, not a replacement for proper electrical practices.
Verify system compatibility: Confirm that the host computer or equipment supports the required USB connectivity.
