USB Adapter Cords

Adapt your USB port to connect to a variety of other devices. These USB cords are backward compatible, so they work with cords and connectors that meet the same or a lower USB standard.

Double-shielded cords have insulation, so they reduce signal interference from nearby equipment and devices.

D-Sub Cords

Connect computers, monitors, printers, and other devices with DB connections.

RS-232 cords transmit data between a modem and another device, such as a computer.

Shielded cords have foil to prevent signal interference from nearby devices. Use them in settings with low to moderate signal interference, such as labs, storage facilities, and offices.

Double-shielded cords have braid and foil for better protection against signal interference than shielded cords. However, the extra shielding adds diameter and reduces flexibility. They’re used in steel mills, machine tool plants, and other heavy processing facilities.

Cords with reversible mounting hardware have removable thumb screws to enable a wider range of mounting options than other cords. Mount them to ports and adapters, as well as directly into panels.
