Often used in automated applications such as robotics, these cords withstand continuous motion without degrading data transmission. The shielding blocks signal interference from nearby equipment and devices. They send data between computers, printers, servers, and switches. For faster data transmission speeds, choose a cord with a higher industry designation category. They’re backward compatible, so they work in networks that meet the same or a lower category. All stand up to some abrasion.

Cords with polyurethane rubber insulation resist abrasion better and bend further than cords with PVC plastic insulation. You can use them indoors or outdoors, though you shouldn’t use them in harsh settings. They’re halogen free.
