About Industry Designation for Cable Insulation

NEMA 5-15 Plug

Also known as hospital-grade cords, these cords have an extra-tight connection to prevent them from detaching. The plug is marked with a green dot.

Use these cords in vehicles and other agricultural and construction equipment. The industry designation is SOOW, so the inner and outer insulation resists oil.

Continuous-Flex Ethernet Cords

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.

Cords with TPE rubber insulation are more abrasion resistant and bend further before kinking than cords with PVC plastic or polyurethane rubber insulation. They also withstand chemicals. Choose them for harsh outdoor environments. These cords are halogen free.

Continuous-Flex USB Cords

Often used in automated applications such as robotics, these cords withstand continuous motion without degrading data transmission. Shielding blocks signal interference from nearby equipment and devices. All are backward compatible, so they work with cords and connectors that meet the same or lower USB standard.

High-Temperature Continuous-Flex USB Cords

A Plug × A Plug

Often used in robotics, packaging, conveyors, and other applications with constant movement and high temperatures, these silicone rubber cords bend and flex at temperatures up to 325° F. Because of their flexibility, they can withstand frequent movement without degrading data transmission. They also have braided shielding to block signal interference from nearby equipment and devices. With a flat construction, these cords take up half as much space as round cords and easily fit inside enclosures and other tight areas. These cords also stand up to water, oil, and UV rays, making them good for use indoors and outdoors. They’re rated ISO Class 1 for use in clean room applications.

All are backward compatible, so they work with cords and connectors that meet the same or lower USB standard—the higher the USB standard, the faster cords can transmit data. The USB connections at each end of these cords withstand temperatures up to 185° F.

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.

Parallel and serial printer cords connect a computer to a printer. Parallel cords transmit data faster than serial printer cords.

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.

Coaxial Cords

Transmit audio, video, and data signals over long distances with minimal signal loss.

Push in RCA and S-video cords to connect.

BNC cords attach with a quarter turn.

SMA and F-Type cords screw on.

RG-58/U and RG-59/U cords are good for low frequency transmissions such as radio signals.

RG-6/U cords are good for medium to high frequency transmissions and are often used in satellite signal transmission.
