FAQs
The L2020CWBK supports back wiring with #18-10 AWG conductors, enabling straightforward terminations. Its four-pole, non-grounding design and 0.36-0.84 inch cord diameter range provide flexibility for common industrial cables, while the stays-on locking mechanism ensures secure, vibration-resistant connections in panels and equipment enclosures.
This connector is rated for 20A, with a voltage rating of 347/600V and an IP67 degree of protection. The four-pole, four-wire configuration (non-grounding) supports robust three-phase power delivery while maintaining ingress protection against dust and water in challenging environments.
Yes. The IP67 rating, NEMA compatibility (L20-20), and rugged Nylon/Santoprene construction make it well-suited for outdoor applications and wash-down zones. It tolerates moisture, dust, and mechanical stress, reducing downtime and maintenance costs in harsh industrial environments.
The L2020CWBK is RoHS compliant and cULus listed, supporting regulatory compliance and safety requirements in many regions. These certifications streamline sourcing decisions, simplify approvals in quality programs, and reduce risk in supplier audits while ensuring reliable performance.
Maintenance is minimized by its durable nylon body, Santoprene seal, and corrosion-resistant nickel-plated brass contacts, which resist wear in dusty or damp environments. The locking mechanism reduces loosening during vibration, lowering rework and downtime, and extending service life for critical industrial connections.
