Measuring only 2.0 x 1.0 x 0.5 inches (5.0 x 25 x 1.2 cm), and packaged in an over-moulded enclosure that protects the circuit board, the USB Port Guardian is small enough to tuck into a pocket or a laptop bag, yet tough enough to stand up to repeated use in harsh environments.
The UH201 USB Port Guardian provides up to 2 kV of protection on the USB line and up to 4 kV ESD contact protection. The isolator is bus powered, has male and female type A USB connectors, and provides 400 mA downstream power when connected to a high-power USB port.
Its high-speed digital isolation chip electrically separates the technician’s PC from the remote I/O device, while allowing full-speed USB 2.0 communications at 12 Mbps – the top of the line for USB isolation products. The isolator also operates reliably over a wide temperature range -40 to +85°C.
Applications include any situation in which a technician must obtain data from equipment in the field, as in industrial control and manufacturing, remote sensing and remote metering, instrumentation, point-of-sale, test and measurement, laboratory information systems and more.
