BB-UHR304
4 Port High Retention USB Full Speed Isolated Hub

  • 4 kV Isolation
  • High Retention USB Connectors
  • Level 4 ESD Protection – 15kV
  • Rugged Metal Case – Panel & DIN Rail Mount
  • Wide Operating Temperature (-40 to 80°C)
  • USB 2.0 – Full Speed (12 Mbps)

The BB-UHR304 is an Industrial Grade Four Port USB Hub. It is designed and tested to meet heavy industrial EMC standards and 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 - requiring up to 3.2 lbs-force to disconnect them. Model BB-UHR304 has 4 kV Isolation between the upstream and downstream USB ports to protect expensive equipment from dangerous ground loops and to help ensure data integrity.

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.
