About NEMA Plugs, Sockets, and Receptacles

Extension Cord Adapters

Change the connection style between an outlet and your equipment.

Abrasion-Resistant Turn-Lock Extension Cords

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

Turn-Lock Extension Cords for Harsh Environments

These cords have an oil- and water-resistant insulation and impact-resistant connectors for protection in harsh environments.

GFCI Turn-Lock Extension Cords

Keep personnel safe from electric shock with these cords.

Extension Cord Splitters

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

Power Cords

Turn-Lock Power Cords

Hardwire these cords to equipment.

Electrical Connectors

Premium Straight-Blade Plugs,
Sockets, and Receptacles

Built to handle tough, repetitive-use applications, these are more durable than standard straight-blade connectors.

Straight-Blade Plugs, Sockets, and Receptacles

Use these connectors in general purpose residential and commercial applications.

Turn-Lock Plugs, Sockets, and Receptacles

Use these general purpose connectors indoors in high vibration applications. A quarter turn locks them together when mated to remain secure in high-vibration applications.

Premium Turn-Lock Plugs, Sockets, and Receptacles

Also known as twist-lock devices, these connectors withstand tough, repetitive use, and are more durable than standard turn-lock connectors. They turn to lock together when mated to prevent accidental disconnection.

Ground-Monitoring Turn-Lock Plugs and Sockets

Check the status of a ground connection—a green light signals that connectors have power and are safely grounded. They turn to lock together when mated to prevent accidental disconnection.

Washdown Turn-Lock Connectors and Cords

When mated, these connectors meet NEMA 6P for protection against washdowns and temporary submersion.

Impact-Resistant Turn-Lock Connectors

A rubber housing protects these connectors from damage caused by drops and impact. They turn to lock together when mated to prevent accidental disconnection.

Corrosion-Resistant Turn-Lock Connectors

Stainless steel hardware and nickel-plated blades or slots protect connections from damage in corrosive environments. These connectors turn to lock together when mated to prevent accidental disconnection.

Non-NEMA Turn-Lock Connectors

A quarter turn locks these connectors in an outlet to remain secure in high-vibration applications and prevent accidental disconnection. They are not compatible with NEMA configurations.

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.

IEC Safe-Break Pin-and-Sleeve Connectors

These connectors meet international standards IEC 309-1 and 309-2. They prevent an electrical arc when separating mated connectors, so you can safely connect and disconnect with the power on.

Hazardous Location Safe-Break
Pin-and-Sleeve Connectors

Use connectors where ignitable gas and dust may be present, such as in refineries and silos. They also prevent an electrical arc when separating mated connectors so you can safetly connect and disconnect with the power on.

Safe-Break Pin-and-Sleeve Connectors

Connect and disconnect with the power on—spring-loaded contacts open like a switch when separating the connectors, preventing an electrical arc.

IEC Pin-and-Sleeve Connectors

Meet international standards IEC 309-1 and 309-2.

Corrosion-Resistant Pin-and-Sleeve Connectors

When used together, connectors maintain a watertight and corrosion-resistant NEMA 4X connection.

Stackable Pin-to-Pin Connectors

Also known as power-pole connectors, these single-pole connectors join two pin connections, rather than a pin and socket. They stack from the top and sides to form any configuration.

Weatherproof DC Connector Sets

Each set includes one plug and one socket. These connectors withstand moisture, harsh engine fluids, and high temperatures. Also known as weather-pack connectors.

Siemens-Compatible Servomotor M23 Connectors

Choose a socket that works with your Siemens servomotor system.
