B&B Electronics Manufacturing Co. Inc. has included two new products in its line of USB isolators. The one-port Ulinx UHR401 and two-port Ulinx UHR402 USB isolators tout tough construction, and are engineered to isolate and protect connected equipment from surges, spikes and ESD.

Ulinx hubs are built to withstand industrial networking hazards such as shock, drop, vibration, electromagnetic interference (EMI) and temperature extremes, boasted B&B Electronics. 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.

UHR401, UHR402

The devices feature 15kV air and 8kV contact ESD protection.

Applications of the devices 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 60601-1 certification.

The Ulinx UHR401 and UHR402 are rated for a temperature range of -40C to 80C. They provide level 4 ESD protection (15kV air, 8kV contact) as well as 4kV isolation between upstream and downstream USB ports. Downstream ports provide full 500mA power to connected devices. The high retention ports hold cables so firmly that it requires 3.2lbs of force to dislodge one, noted the company. The Ulinx UHR401 and UHR402 are shipped with an external power supply that has US, EU and UK blades. An optional locking barrel plug can be purchased separately.

The UHR401 is priced at $169. The UHR402 is priced at $179. Both models carry a five-year warranty.
