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.

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.

A quarter turn locks these connectors in place to remain secure in high-vibration applications and prevent accidental disconnection. They are not compatible with NEMA configurations.

Styles A, B, C, and D are also known as California Standard plugs, sockets, and receptacles. Plugs have one slot to accept a grounding pin; sockets and receptacles have one grounding pin.

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, and IP69K, they're protected against corrosion, oil/coolant seepage, washdowns, and high-temperature, high-pressure washdowns.

Connect and disconnect with the power on—spring-loaded contacts open like a switch when separating the connectors, preventing an electrical arc. These connectors are approved as switch-rated connectors for branch circuit and motor circuit disconnect switching. When mated, they form a NEMA 4X rated connection that resists corrosion and protects against washdowns. A ground pin is included in the number of wires.

Receptacles include a junction box with a conduit entry hub.

Finger drawplates (sold separately) create a grip around plugs and sockets or receptacles, making it easier to pull them together tightly when mating.

Caps (sold separately) protect plugs when not in use.

Use connectors where ignitable gas and dust may be present, such as in refineries and silos. They are CSA certified for Class I, Division 2, Groups A, B, C, and D; and Class II, Division 2, Groups F and G. All have a chamber that withstands the pressure of an internal ignition—isolating it from spreading to the surrounding environment. They're rated IP66 and IP67 for protection from washdowns and temporary submersion.
