Eaton L1020PW Watertight locking plug - IP67 rated
Part Number: L1020PW
Quick Summary
The Eaton L1020PW watertight locking plug provides secure, back-wired connections for industrial equipment in wet environments, delivering reliable power in washdown and outdoor settings. Historically, moisture ingress and conduit moisture damage cause unexpected downtime; this receptacle is designed to resist water exposure and harsh cleaning cycles. It carries RoHS compliance, cULus listing, and IP67 protection, with industrial-grade materials to meet demanding electrical codes and operator safety expectations. For procurement and installation, its 125/250V rating, back-wiring method, and 0.43–1.15 in cord diameter compatibility simplify field wiring while reducing labor time. This combination supports lower total cost of ownership through longer service life and fewer callouts in demanding industrial environments.

FAQs
The L1020PW provides dependable power delivery for industrial equipment in harsh, moisture-prone environments. It supports 20A circuits at 125/250V, uses a three-pole, three-wire non-grounding configuration (L10-20), and features IP67 protection with a durable yellow nylon housing and Santoprene seal. This makes it ideal for washdown areas, outdoor installations, and control panels requiring reliable mating and sealing.
Back wiring accepts #18-10 AWG conductors; remove terminal access, insert conductors into the appropriate poles, and tighten to the specified torque of 14–16 lbf-in. The nickel-plated brass contacts ensure reliable termination, while the Santoprene seal maintains IP67 protection. Verify polarity and secure seating before mating with a corresponding receptacle.
Yes. The L1020PW carries IP67 protection and RoHS compliance, along with cULus listing (NOM). It is designed for environmental resistance including NEMA 4, 4X, 6, and 6P scenarios, making it suitable for outdoor, washdown, and heavy industry installations. These certifications help meet regulatory requirements and reduce risk for systems exposed to moisture, dust, and chemical exposure.
Key installation considerations include wiring size (#18-10 AWG), back-wiring method, cord diameter compatibility (0.43–1.15 in), and a compact footprint (2.49 in width and height). The unit weighs about 0.25 lb, which simplifies handling in tight panels. Torque spec is 14–16 lbf-in for secure mating, and the yellow nylon housing with Santoprene seal supports reliable operation in wet environments.
Investing in the L1020PW yields measurable ROI through reduced maintenance labor, fewer moisture-related outages, and longer service life in harsh facilities. The rugged locking mechanism minimizes accidental disconnection, while back wiring simplifies field terminations for faster commissioning. With RoHS and cULus compliance, users can confidently meet safety codes and environmental requirements across manufacturing, food and beverage, and water-treatment applications.
