B&B Electronics Ltd. has expanded its family of USB isolators. Designed to isolate and protect connected equipment from surges, spikes and electrostatic discharges carried on USB cable, the new one-port Ulinx UHR401 and two-port Ulinx UHR402 USB isolators also protect themselves by virtue of their rugged construction. Unlike consumer-grade USB hubs, Ulinx hubs are built to withstand industrial networking hazards like shock, drop, vibration, electromagnetic interference (EMI) and temperature extremes.
