USB isolators have been developed by B&B Electronics to isolate and protect connected equipment from surges, spikes and electrostatic discharges carried on the USB cable.
The new one- and two-port USB isolators feature a rugged design for greater durability.
In contrast to consumer-grade USB hubs, the new devices are built to withstand industrial networking hazards such as, shock, drop, vibration, electromagnetic interference (EMI) and temperature extremes.
They are equipped with high retention ports that hold USB cables firmly in place to eliminate data loss, and in extreme cases, the risk for fire caused by loose cables and arcing.
Applications include industrial control and manufacturing, remote sensing and remote metering, instrumentation, point-of-sale, test and measurement, laboratory information systems (LIMS) and medical applications requiring EN 60601-1 certification.
The devices are rated for a temperature range of -40 to 80°C.
They provide Level 4 ESD protection (15kV air, 8kV contact) as well as 4kV isolation.
