Eaton L1820CW Watertight Locking Connector - IP67

Engineered for washdown and outdoor installations, the L1820CW leverages IP67 protection along with NEMA 4, 6, 6P and 4X ratings. This combination guards against water ingress, dust, and corrosive environments, extending service life and reducing corrective maintenance in harsh facilities. This design also supports rapid replacement in maintenance cycles. Back wiring simplifies field termination by routing conductors directly into the device, minimizing exposed conductors and accelerating panel assembly. The unit accepts #18-10 AWG conductors, with a maximum cord diameter of 0.36-0.84 inches, and relies on a secure locking mechanism to maintain contact reliability under vibration. This approach reduces wiring errors, speeds installation, and minimizes space inside enclosures. Compatibility with standardized panels helps with procurement and stocking. Configured as L18-20, three-pole, four-wire, 120/208 V, this locking connector supports standard three-phase service used in motors, pumps, and industrial controls. The 20A rating with a 14-16 lbf-inch torque specification ensures tight, vibration-resistant connections in dynamic environments. Industry-standard mounting and cable routing practices are supported. Face and body made of nylon with nickel-plated brass contacts provide dependable mechanical strength and corrosion resistance. Santoprene thermoplastic elastomeric seal materials deliver enduring watertight performance across temperature swings and chemical exposure. This combination minimizes wear and ensures long-term reliability in high-heat zones. Designed for industrial back-panel installations, the L1820CW’s yellow color aids identification in busy control rooms and outdoor rigs. The locking mechanism prevents accidental disconnection, even in equipment subject to vibration. Color coding aids preventative maintenance checks. Field service is simplified by clear labeling and standard sizing, enabling technicians to swap connectors quickly without rewiring. When used in compliant assemblies, it supports RoHS and cULus NOM certifications, aligning with global supplier requirements. It also helps reduce spare-part diversity and streamline maintenance schedules. For OEMs and maintenance teams, this Eaton solution offers predictable performance, lower total cost of ownership, and a safer, more reliable power distribution point in industrial automation environments. The content ensures long-term reliability and easier expansion in scalable control architectures.
