Also known as twist-lock devices, these connectors withstand tough, repetitive use, and are more durable than standard turn-lock connectors. They turn to lock together when mated to prevent accidental disconnection.

Stainless steel hardware and nickel-plated blades or slots protect connections from damage in corrosive environments. These connectors turn to lock together when mated to prevent accidental disconnection.

Use connectors where ignitable gas and dust may be present, such as in refineries and silos. They also prevent an electrical arc when separating mated connectors so you can safetly connect and disconnect with the power on.

Meet international standards IEC 309-1 and 309-2.
