Rugged, Industrial-Strength USB Hub


ACCES I/O Products, Inc., is pleased to announce the availability of a rugged, industrial-strength 4-port USB hub that mounts in a 3.5 inch drive bay—model USB-3.5-HUB. This small industrial/military grade hub features extended temperature operation (-40°C to 85°C), high retention USB connectors, and an industrial steel drive bay mounting bracket for shock and vibration mitigation. The 3.5″ front panel drive bay mounting provision allows for easy installation in rack-mount industrial and military grade style chassis, as well as in home or office PCs.

The USB-3.5-HUB now brings four high-performance USB ports with high retention type A connectors to the front panel of your PC. The unit makes it easy to add USB-based I/O to your embedded system or to connect peripherals such as external hard drives, GPS, wireless and more. Real-world markets include Industrial Automation, Embedded OEM, Transportation/Automotive, Military/Government, and Home, Office or Production Workstations.

This versatile 4-port hub is self-powered directly from the Berg connector (3.5″ floppy drive power connector) fed from the PC power supply and can provide a full 500mA source at 5V on each of the downstream ports. Available accessories include embedded OEM USB cables for connecting to an available host USB port on your motherboard (either standard or metric spacing) and a power splitter cable in case your Berg connector is already being used.
