Feature → Business Impact → Application: The watertight locking design creates a secure, vibration-resistant connection that minimizes accidental disengagement in noisy or rugged environments, reducing downtime and rework in conveyors and packaging lines. This translates to higher line uptime and lower maintenance costs. The L23-20/NEMA configuration and four-pole, five-wire arrangement enable comprehensive power distribution for industrial drives and motor starters, simplifying panel layouts and enhancing fault isolation in automation cabinets. Compatibility with #18-10 AWG conductors and back-wiring wiring method speeds installation and reduces field labor, which is critical for retrofit projects and high-mix, low-volume production lines. The Santoprene elastomer seal and nylon body deliver durable resistance to oils, solvents, and temperature cycling, supporting long service life in manufacturing floors. With IP67 and NEMA ratings, operators gain reliable moisture ingress protection, meeting safety and reliability targets while maintaining compliance with RoHS and cULus requirements. This combination of features supports faster commissioning, improved repeatability, and lower total cost of ownership for industrial electrical installations.

FAQs
The L2320CWBK supports back-wiring for conductors in the range of #18 to #10 AWG. This broad compatibility enables straightforward integration with common control and power skins in industrial cabinets, minimizing the need for sub-assembly changes and reducing installation time on retrofit projects.
The connector is rated for 20A at 347/600V and features IP67 sealing with NEMA L23-20 configuration for four poles and five wires, including a grounding conductor. These ratings ensure suitability for rugged, wash-down environments while maintaining safe operation and compliant performance in modern automation systems.
Yes. With IP67 environmental protection and NEMA 4/4X coating endurance alongside NEMA 6/6P listings, this connector excels in outdoor and washdown environments. The watertight design plus Santoprene elastomer seal minimizes moisture ingress, helping maintain reliability in challenging industrial settings such as outdoor chemical plants and packaging lines.
Install using back-wiring with conductors within #18–10 AWG, and apply appropriate torque per conductor size (14–16 lbf-in for #10–14 AWG; 20 lbf-in for #8 AWG). Use the four-pole, five-wire configuration with grounding, and ensure the mating half is properly secured to maintain IP67 integrity in operation.
The connector is RoHS compliant and cULus Listed, confirming compliance with environmental and safety standards for industrial electrical components. This supports procurement workflows that require traceable certifications and aligns with quality management systems in many automation projects.
