ACCES I/O: rugged, industrial grade 4-port SuperSpeed USB 3.1 hub

ACCES I/O Products reveals a new rugged, industrial-strength, 4-port USB 3.1 hub—the USB3-104-HUB. Designed for the harshest environments, this small industrial/military grade hub features extended temperature operation, locking USB and power connections, and an industrial steel enclosure for shock and vibration mitigation. The OEM version (board only) is PC/104 sized and can easily be installed in new or existing PC/104-based systems as well. The USB3-104-HUB makes it easy to add USB-based I/O to your embedded system or to connect peripherals such as external hard drives, keyboards, GPS, wireless and more. Real-world markets include Industrial Automation, Security, Embedded OEM, Laboratory, Kiosk, Military/Mission Critical, Government, and Transportation/Automotive.

This versatile four port hub can be bus powered or self (externally) powered. You may choose from two power inputs (power jack and terminal block) to provide a full 900mA source at 5V on each of the downstream ports. Additionally, a wide input power option exists to accept from 7VDC to 28VDC. All type A and type B USB connections feature a locking, high retention design that complies with class 1, Div II minimum withdrawal requirements. Over 11 pounds of force (50 Newtons), is required to disconnect a cable from the type A connectors. These connectors have a positive locking tab to quickly differentiate it from standard USB connectors. The Type B connection follows the USB3 Vision standard and features a screw lock USB cable to ensure secure connection to the USB3-104-HUB. Using the locking/latching USB connections on this hub increases reliability in your system and prevents accidental disconnection.

Available accessories include a wide variety of standard USB cables and mounting provisions for quick and easy-to-use, out of the box, connectivity. Mounting provisions include DIN rail and various panel mounting plates. Also, external instrument-grade power supplies are available. No driver installation is required for the USB3-104-HUB. Any USB compliant operating system will automatically install it. It will enumerate as a Generic Hub which uses the USB Hub Class Driver that is built into USB compliant operating systems such as Linux (including macOS) and Windows.
