Seven Port Industrial Grade USB Hub

  • 4 kV Isolation (UHR307)
  • High Retention USB Connectors
  • ESD Protection – 15 kV Air
  • Rugged Metal Case
  • Wide Operating Temperature (-40 to 80°C)
  • USB 2.0 – Refer to Specification Table
  • Panel Mount Brackets & DIN Rail clip


The UHR207 and UHR307 are Industrial Grade Seven Port USB Hubs. Model UHR307 includes 4 kV isolation. They are designed and tested to meet heavy industrial EMC standards. High retention USB connectors hold standard USB cables tight and are perfect for high vibration applications – requiring up to 3.2 lbs-force to disconnect them.

The Heavy Industrial EMC specifications allow these hubs to operate where standard office grade hubs fail – such as near variable frequency drives, motor control centers, welding, and other large electrical loads.

4 kV Isolation (UHR307) between the upstream and downstream USB ports protects expensive equipment from dangerous ground loops and helps ensure data integrity.

They are powered from an external 10 to 30 VDC source. Two power connectors are provided – terminal block or threaded / lockable barrel plug. Refer to ordering information for power supply recommendation. Each downstream port provides up to 500 mA of power to connected USB devices.
