Powered exclusively by the host USB port, it provides downstream devices with 100 mA of power and High Speed USB connectivity at 480 Mbps. Designed for easy mounting in harsh environments and cramped spaces, the mini (2.4 x 1.75 x 1.10 in, 6.1 x 4.45 x 2.79 cm) USB hub features a rugged ABS plastic housing, built-in mounting tabs, a wide (-40 to 80°C) operating temperature, and B&B Electronics’ signature high-retention USB connectors that require up to 3.4 lbs. of force to disconnect, ensuring tight connections even in high-vibration situations.
The UH104 is made primarily for industrial automation, instrumentation, security, kiosks, point-of-sale and laboratory market applications. The hub is designed, tested and proven rugged enough for industrial EN61000-6-1 harsh environments. Its construction was validated using IEC60068-2-32 drop testing, and it also adheres to 15 kV ESD protection and FCC / CISPR Class B standards.
This entry-level hub shares many of the features of B&B’s top-of-the-line USB hubs, although it does not include their built-in surge protection and electrical isolation, features that are intended for use in ultra-rugged applications.
