About Extension Cords

NEMA 5-15 Plug

NEMA 5-15 Socket

The insulation on these cords resists water, so they can be used outdoors.

SJTOW cords have an oil-resistant insulation.

GFCI Extension Cords

Keep personnel safe from electric shock with these cords. The industry desgination is SJTW, so the insulation resists water.

Cords with a 90° elbow plug fit flush against a wall outlet, so they fit behind machinery or in areas where space is tight.

Cords with manual GFCI reset prevent unexpected start-up.

Intended to withstand demanding applications, these reels have a steel housing and an oil- and water-resistant extension cord. The automatic take-up feature maintains constant tension on the extension cord as the spring-driven winding mechanism retracts it. An adjustable ball lock controls how much cord retracts into the reel.

Reels with a swing-mount bracket dispense cord at any angle.

Ethernet Cords

These Ethernet cords are backward compatible, so they work in networks that meet the same or a lower category. They send data between computers, printers, servers, and switches.

Shielded Ethernet Cords

The shielding on these cords 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.

Cords with braid and foil shielding have better protection than cords with only foil shielding, which is especially important for higher transmission speeds or longer lengths of cord. However, the added shielding increases cord diameter and reduces flexibility.

90° elbow plugs fit flush against equipment, so they fit behind machinery or in areas where space is tight.

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.

Washdown USB Cords

Rated IP67, these cords withstand washdowns and temporary submersion. Connect them to a USB device inside an enclosure. Shielding blocks signal interference from nearby equipment and devices. The higher the USB standard, the faster cords can transmit data. All are backward compatible, so they work with cords and connectors that meet the same or lower USB standard.

Cords with a socket mount onto a panel.

Locking-pin cords have an IP67 rating when used with a cap (sold separately) on the socket end.

Crush-Resistant USB Cords

The insulation serves as a tough armor that protects these cords in high-traffic areas. Shielding blocks signal interference from nearby equipment and devices. They’re backward compatible, so they work with cords and connectors that meet the same or lower USB standard.

Cords with PVC armor are more lightweight than cords with stainless steel armor.

Stainless steel armor is more crush resistant than PVC armor.

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.

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.
