About NEMA Plugs, Sockets, and Receptacles

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.

Space-Saver Turn-Lock Plugs,
Sockets, and Receptacles

A good fit for tight spaces, these connectors are also known as NEMA midget plugs. 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.

Interference-Limiting Turn-Lock Receptacles

Protect computers and other sensitive equipment from signal interference; these receptaces are also known as isolated ground receptacles. 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.

Caps for Washdown Plugs and Sockets

Protect plugs and sockets in washdown environments when not in use.

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.

Harsh Environment Turn-Lock Connectors

Rated NEMA 6P, NEMA 13, IP66, and IP69K when mated, these connectors withstand high-pressure, high-temperature washdowns, oil/coolant splashing, and are corrosion-resistant so they can be used in high-vibration marine environments.

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.

Straight-Blade/Turn-Lock Connectors

Combine straight-blade and turn-lock styles in one receptacle for convenience.

Turn-Lock Vehicle DC Connectors

Connectors lock into place for a secure connection in high-vibration environments. They power small devices, such as chargers for electronics, from a vehicle. Also known as cigarette-lighter plugs and sockets.

Cords

Turn-Lock to Straight-Blade Adapters

Change a turn-lock to a straight-blade connection, or a straight-blade to a turn-lock connection.

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.

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

Give the connectors on these cords a quarter turn to lock in place.

Turn-Lock Power Cords

Hardwire these cords to equipment.
