Eaton L2120PWBK Watertight Locking Plug - IP67

Watertight protection and rugged housing are at the core of the L2120PWBK, delivering IP67-rated performance in wet or dusty industrial settings. This design minimizes water ingress and debris intrusion, lowering the risk of corrosion and unplanned downtime during washdowns and outdoor operation. The four-pole L21-20 configuration with five conductors supports three-phase power and grounding in a compact back-wiring package. This wiring method enables faster field terminations and reduces miswiring risk, translating into quicker panel builds and fewer callouts. Nickel-plated brass contacts, nylon body, and Santoprene seals provide durable, low-resistance connections. The combination resists corrosion and wear, improving contact integrity across temperature swings and washdown cycles. The 20A, 120/208V rating enables common industrial loads such as motors, controllers, and lighting in a single connector, while back-wiring simplifies terminations for technicians with existing wire-in devices. With a torque rating of 14-16 lbf-in, mating components seat securely, resisting vibration and loosening. This precise torque control supports reliable long-term operation in equipment subject to shocks. RoHS compliance and cULus listing ensure regulatory and environmental compliance across North America, while IP67 and related environmental ratings support safe, compliant installation. Back wiring reduces install time and training costs, enabling standardization across multi-site facilities.
