Industrial-Grade USB Hubs
The most rugged USB Hub on the Market!
Our Industrial Grade USB Hubs are designed for the harshest environments. They are EMC tested to meet heavy industrial standards. The four port hubs are UL listed for Class 1 Division 2 hazardous locations. High retention USB connectors hold standard USB cables tight and are perfect for high vibration applications. The UHR304 and UHR307 offer 4 kV Isolation between the upstream and downstream USB ports to protect expensive equipment from dangerous ground loops and to help ensure data integrity. No doubt about it, these hubs will operate where standard office grade hubs fail – such as near variable frequency drives, motor control centers, welding, and other large electrical loads.

When deciding between the isolated models and the non-isolated models, you should be aware that isolation technology available on the market today is limited to 12 Mbps. USB 2.0 devices operate at one of three speeds. Low speed devices, such as a keyboard or mouse, operate at 1.5 Mbps (USB 1.1). This is called “Low Speed.” Other devices, such as scanners or printers may operate at 12 Mbps (USB 1.1). This is called “Full Speed.” Devices such as USB video cameras may require 480 Mbps (USB 2.0). This is called “High Speed” USB. Our USB Hubs support 2.0 – However, the isolated hubs do not support “High Speed” 480 Mbps and will ratchet back to 12 Mbps.
The UHR204, our non-isolated four port hub, can operate on USB Bus Power. In this mode, it provides 100mA per port to downstream devices. It can also be powered from an external source if you need 500 mA to downstream devices. The UHR304, our isolated four port hub, and both the isolated and non-isolated seven port hubs, require external power. External 10 to 30 VDC can be provided through the removable terminal block connection or a handy threaded barrel plug if you desire our wall transformer power supply. The external power supplies are sold separately. Review the accessories tab for more information.
All of our industrial grade hubs include a mounting accessory package that includes a DIN Rail Clip for attaching to a standard 35mm DIN Rail. It also includes mounting brackets that can be used to mount the hubs to any flat surface.
