Premium Turn-Lock Plugs, Sockets, and Receptacles

Also known as twist-lock devices, these connectors are built to handle tough, repetitive-use applications, and are more durable than standard turn-lock connectors. A quarter turn locks them in place to remain secure in high-vibration applications and prevent accidental disconnection.

Receptacles for outlet boxes fit standard wall plates (not included).

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. A red light indicates power only. The lights are visible from any angle for quick identification. A quarter turn locks connectors in place to remain secure in high-vibration applications and prevent accidental disconnection.

Washdown Turn-Lock Connectors and Cords

When mated, connectors meet NEMA 6P for protection against corrosion and washdowns. All have a multiple-ring seal and rubber housing to keep out liquid. They resist heat, oil, and chemicals. A quarter turn locks them in place to remain secure in high-vibration applications and prevent accidental disconnection.

Plugs mate with female receptacles and female sockets with an attached cover.

Male receptacles mate with female sockets without an attached cover.

Harsh Environment Turn-Lock Connectors

Rated NEMA 6P, NEMA 13, IP66, and IP69K when mated, connectors withstand high-pressure, high-temperature washdowns, oil/coolant splashing, and are corrosion resistant so they can be used in marine environments. They require a quarter turn to mate.

Plugs have a multiple-ring seal to keep out liquid when mated. They have a locking ring that screws together with sockets and receptacles so connections remain secure in high-vibration applications such as oil drilling and mining operations.

Sockets and receptacles have an attached cover that creates a watertight seal when not mated.
