IP67 watertight construction delivers reliable protection against moisture, dust, and washdown exposure. This reduces moisture-related insulation damage, corrosion, and unexpected downtime, lowering total cost of ownership for industrial machinery. It is particularly valuable in outdoor installations, food-and-beverage processing zones, and metal fabrication lines where water jets are common and ingress protection is mandatory. NEMA L21-20 four-pole, five-wire configuration with 120/208V three-phase capability enables direct, safe power delivery to mixed loads. The business impact is clearer phase balance and reduced connector mismatches, supporting faster setup and fewer field rewires. This makes it well-suited for CNC machines, pumps, and conveyors in manufacturing plants that rely on standardized industrial connectors. Back wiring for #18-10 AWG conductors simplifies field terminations and improves reliability where terminal access is limited. The advantage is faster installations and easier maintenance, which translates to lower labor costs and fewer terminated connections. This setup is ideal for retrofit projects and new equipment installs in control panels and power distribution enclosures. Corrosion-resistant nickel-plated brass contacts and a Santoprene seal inside a nylon body deliver durability in harsh environments. The business impact is extended contact life and consistent conductivity, reducing replacement parts and ensuring stable performance in salt spray and washdown conditions. The color-coding (yellow) aids quick identification in high-activity lines and large multi-connector panels. A torque rating of 14-16 lbf-in supports secure mating without over-torquing, improving safety and connector integrity. The device's RoHS compliance and cULus listing provide regulatory assurance, while IP67 environmental resistance covers NEMA 4X/6 for rugged installations. Together these features support predictable maintenance windows and improved uptime across industrial facilities.

FAQs
The L2120PW supports back wiring and accepts #18-10 AWG conductors, enabling straightforward terminations in control panels and power enclosures. To install, prepare conductors, insert through the back-wiring terminals, secure with appropriate torque, and verify insulation integrity. This approach reduces field termination time and improves reliability in tight installation spaces.
Key ratings are 20A and 120/208V with a four-pole, five-wire configuration for L21-20. The torque specification is 14-16 lbf-in to ensure secure mating without over-torquing, which preserves contact integrity and reduces loosening in vibration-heavy environments.
Yes. The L2120PW is designed for 3ØY 120/208V and uses a NEMA L21-20 configuration with IP67 protection, enabling safe operation in harsh environments, washdowns, and outdoor installations. Its rugged materials and locking mechanism minimize misconnection risks in conveyors, pumps, and CNC machines.
The plug carries RoHS compliance and cULus listing, along with IP67 protection and NEMA 4X/6 ratings, addressing regulatory and environmental requirements typically encountered in food, beverage, and general industrial facilities.
The L2120PW reduces downtime through reliable moisture protection, corrosion resistance, and robust back-wiring terminations. Its durable nickel-plated contacts and Santoprene seals lower maintenance parts replacement, while easy installation accelerates project timelines, delivering measurable total-cost-of-ownership improvements.
