Cords

Extension Cords

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

Extension Cords for Harsh Environments

The insulation resists water, oil, and chemicals, so these cords withstand dirty and greasy environments.

Abrasion-Resistant Extension
Cords for Harsh Environments

Run these cords through high-traffic areas that are dirty and greasy. They have a thick insulation that resists water, oil, and chemicals, and protects against abrasion.

Abrasion-Resistant Extension Cords

Thick insulation protects the internal wires of these cords, so they can be used in high-traffic areas and over rough surfaces.

Multi-Outlet Extension Cords

Power multiple devices with one extension cord.

Light Duty Multi-Outlet Extension Cords

Designed for indoor use, these cords are often used to power appliances.

Coiled Extension Cords

These self-coiling cords return to their retracted length after stretching for tangle-free storage.

Locking Extension Cords for Harsh Environments

Keep power flowing in dirty areas with rubber-insulated cords that resist oil, water, and chemicals. A locking lever on the socket prevents your device from disconnecting.

Sure-Grip Extension Cords

Also known as hospital-grade cords, these have extra-tight connections to prevent them from detaching. The connectors are marked with a green dot.

Locking Extension Cords

A locking lever on the female socket prevents your device from disconnecting.

Extension Cord Splitters

Attach these splitters to an extension cord to power multiple devices from one cord.

Power Cords

Connect equipment and devices to a power supply.

Light Duty Power Cords

Designed for indoor applications, these cords are often used to power appliances.

Sure-Grip Power Cords

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.

Electronic Equipment Power Cords

Use these cords with computers, lab equipment, and office machines that have IEC connections.

Sure-Grip Electronic Equipment Power Cords

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.

Electronic Equipment Cord Splitters

Power multiple devices from one power source.

Sure-Grip Locking Electronic
Equipment Cord Splitters

Create secure, vibration-resistant connections on both ends—these cord splitters have a hospital-grade plug and locking sockets.

Mini Cords

With a higher maximum current than nano M8 and micro M12 cords, these mini cords are often used with automated systems, motors, and pumps.

Harsh Environment Mini Cords

Often used for automated systems, motors, and pumps in tough industrial areas such as near welding and metal machining, these cords carry higher current than M5, M8, and M12 cords.

Sure-Grip Outlet Strips

Also known as hospital-grade outlet strips, these outlets have an extra-tight fit to prevent plugs from detaching. They are marked with a green dot.

Covered-Cord Outlet Strips

A combination of an outlet box, cord, and duct, these outlet strips minimize tripping hazards and protect the cord from damage.

Automatic-Wind Cord Reels

A ratchet holds the extension cord on these reels in place at any length; a quick pull releases the cord and the spring-driven winding mechanism retracts it.

Impact-Resistant Automatic-Wind Cord Reels

Made of impact-resistant plastic, these reels are more durable than other automatic-wind cord reels.

Water-Resistant Automatic-Wind Cord Reels

Make power accessible in wet and outdoor environments with these cord reels that resist water, oil, and UV light. A tug on the extension cord winds it up automatically, so you don’t have to wind it yourself.

Electrical Connectors

Mini Connectors

Often used to send power and signal to automated systems, motors, and pumps, these mini connectors carry higher currents than M5, M8, and M12 connectors.

Harsh Environment Mini Connectors

Send higher current than M5, M8, and M12 connectors near tough industrial jobs, such as welding and metal machining.

Shielded Mini Connectors

Protect against signal interference while sending 2-3 times more current than M12 connectors.

Sanitary Mini Connectors

Send higher current than M12 connectors to automated systems, motors, and pumps in environments where washdowns are common.

Mini Splitters

Simplify wiring and reduce the number of cords in your automation setup.

Deutsch-Style DC Connectors

Use these connectors in vehicles and other agricultural and construction equipment.

Weatherproof Molex Compact Connector Sets

A sealed housing protects connectors from weather. Sets include a plug and socket with wire leads already installed. They fit standard Molex connectors.

Build-Your-Own AMP Compact Connectors

Configure a connector for your application—combine housings with pins and sleeves for different wire sizes. They fit AMP MATE-N-LOK connectors.

AMP Compact Connector Sets

Connectors come assembled with wire leads already installed, so they can be quickly added to existing wiring systems. Use them with AMP MATE-N-LOK connectors.

Mil. Spec. Compatible Connectors

These connectors have the same pin and socket configuration as connectors that meet MIL-DTL-26482, so they can be used with products that meet the same standard. Quickly mate them by pushing them together.

Mil. Spec. Push-In Connectors

These connectors meet MIL-DTL-26482, so they're compatible with other products that meet the same standard. Quickly mate by pushing them together.

Mil. Spec. Screw-Together Connectors

Rated to MIL-DTL-5015 specifications, these connectors are compatible with other products that meet the same standard. They screw together for a secure connection.
