Ruggedized USB isolators provide Level 4 ESD protection for industrial environments
March 13, 2012 // Julien Happich
B&B Electronics has expanded its family of USB isolators with the one-port Ulinx UHR401 and two-port Ulinx UHR402 USB isolators. Designed to isolate and protect connected equipment from surges, spikes and electrostatic discharges carried on USB cable, the devices 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. 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 Ulinx UHR401 and UHR402 are rated for a temperature range of -40 to +80°C. They provide Level 4 ESD protection (15 kV air, 8 kV contact) as well as 4 kV isolation between the upstream and downstream USB ports. Downstream ports provide full 500 mA power to connected devices. The high retention ports hold cables so firmly that it requires 1.45Kg of force to dislodge one. The Ulinx UHR401 and UHR402 are shipped with an external supply that has US, EU, and UK blades. An optional locking barrel plug can be purchased separately. Both models carry a five-year warranty.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
