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.

Interference-Limiting Turn-Lock Receptacles
Protect computers and other sensitive equipment from electromagnetic interference (EMI). Also known as isolated ground receptacles, they have a ground terminal that is insulated from the mounting strap so you can run an isolated ground wire through the conduit. When mated with a plug, a quarter turn locks them in place to remain secure in high-vibration applications and prevent accidental disconnection. Receptacles fit standard wall plates (not included).

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.
