Build-Your-Own Latching Connectors

Male

Female

Configure a connector for your application—combine male and female inserts with a base and a hood. Select components based on the number of poles needed. To protect connections while maintaining access, the base and hood latch together securely, yet can be quickly detached for equipment repair or replacement. Once assembled, these connectors are rated NEMA 4X, 12, and IP65 for protection against corrosion, washdowns, dirt, oil/coolant dripping, and water projected from a nozzle.
