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).

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.

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).

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.

Stainless steel hardware and nickel-plated blades or slots protect connectors from damage in corrosive environments. 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).

A rubber housing protects these connectors from damage caused by drops and impact. Lock them in place with a quarter turn to remain secure in high-vibration applications and prevent accidental disconnection. Not intended for use in wet or damp environments.

The plug on these cords turns to lock in an outlet, so they remain securely attached in high-vibration applications.

Change the connection style between an outlet and your equipment.

Adapters with a power-indicating light have a light on the socket that illuminates when the adapter has power.

STW and SJTW adapters have a water-resistant outer insulation. STOW and SJTOW adapters have an oil- and water-resistant outer insulation.

These cords have an oil- and water-resistant insulation and impact-resistant connectors for protection in harsh environments. Give the connectors a quarter turn to lock in place; they remaining secure in high-vibration applications.

Thick insulation protects the internal wires of these cords, so they can be used in high-traffic areas and over rough areas. The insulation also resists water. Give the connectors a quarter turn to lock in place; they remain secure in high-vibration applications.
