Locking mechanism ensures secure mating even in high-vibration equipment, dramatically reducing accidental disconnections and mid-run outages. This improvement translates to fewer service calls and shorter maintenance windows, boosting overall line uptime. It is particularly beneficial for conveyors, press lines, and outdoor equipment where connectors are exposed to movement and environmental stress. Three-pole, four-wire configuration with back wiring supports clean, safe power distribution. The arrangement guarantees correct grounding and phase integrity, minimizing mis-wiring risks during installation. This makes it ideal for panel builders and OEMs wiring motors, drives, and control circuits in industrial facilities. Cord diameter range of 0.44-1.06 inches and #10-4 AWG allowable sizes offer flexible termination options without re-terminating hardware. The back-wiring method speeds field terminations and reduces assembly time, cutting labor costs. Nylon housing with glass-filled body and zinc-plated brass contacts provide chemical resistance and long service life. The rugged construction supports operating temperature range -40 to 105 °C and a torque rating of 45 lbf-in, ensuring consistent torque and reliable contact retention across cycles. Compliance and sourcing benefits include cULus listing, Federal Specification 6221 02, and California standard. These certifications simplify audits, help meet safety requirements, and support ongoing maintenance programs across multiple sites.
