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 4X, 6P, and IP67 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.

IEC Safe-Break Pin-and-Sleeve Connectors

These connectors meet international standards IEC 309-1 and 309-2, so they’re compatible with other IEC 309 devices. They allow you to connect and disconnect with the power on—spring-loaded contacts open like a switch when separating the connectors, preventing an electrical arc. All are approved as switch-rated connectors for branch and motor circuit disconnect switching. Connectors have a ground pin that is included in the number of wires. Rated NEMA 4X, 12, IP67, and IP69K, they're protected against corrosion, oil/coolant seepage, washdowns, and high-temperature, high-pressure washdowns.
