Lilutong L20 Series IP68 Waterproof Connectors
——Engineered for Excellence in Global Outdoor Lighting Systems
UL-Certified Innovation for Harsh Environments
The L20 Series IP68 Waterproof Connectors by Lilutong Connector Co., Ltd. redefine reliability in outdoor lighting infrastructure. Designed to meet UL2238 (Industrial Control Equipment Connectors) and UL1977 (Component Connectors for Use in Communications Systems) standards, these connectors integrate clip-terminal quick-connect, solder-in, and threaded locking mechanisms to optimize cable management and ensure uninterrupted performance in extreme conditions.
Certified Performance Highlights (per UL2238/UL1977):
- Temperature Resilience: Operates at -40°C to +105°C (UL1977 Section 6.1), withstanding thermal cycling in Nordic winters and desert summers.
- Current & Voltage Compliance: Rated for 10A continuous current and 300V AC/DC (UL2238 Table 7.1), supporting high-power LED arrays in stadiums and highways.
- Mechanical Durability: Survives 5,000+ mating cycles (UL1977 Clause 8.3) with <5mΩ contact resistance variance, ideal for high-traffic urban lighting.
How the L20 Series Dominates Outdoor Lighting Projects
1. Cable Management Revolution
- Modular T/Y/X-Type Configurations: Simplify branching in complex layouts (e.g., Oslo Smart City Lighting), reducing installation time by 50% vs. traditional junction boxes.
- Self-Locking Clip Mechanism: UL2238-tested 25N tensile strength (Clause 9.3) prevents accidental disconnections in hurricane-prone coastal zones.
2. UL-Validated Waterproof Integrity
- Triple-Seal Architecture: Exceeds UL1977 72-hour salt spray (Clause 7.4) and 1m submersion (IP68) requirements, proven in Chicago Riverwalk LED upgrades.
- Vibration Resistance: Passes 10-55Hz/1.5mm amplitude vibration tests (UL2238 Clause 8.2), ensuring stability in subway tunnel lighting.
3. Hyper-Customizable Core Options
- 2-18 Core Flexibility: From basic 2-core pathways to hybrid 3+8-core smart lighting systems, all compliant with UL1977 insulation resistance (>1000MΩ, Clause 5.2) and dielectric strength (1500V AC, Clause 5.3).
- Quick-Latch Design: Achieves UL2238 50N insertion/removal force (Clause 9.2) for tool-free maintenance in Parisian monument lighting.
Global Market Leadership
1. North American Expertise
- CTO Credentials: Mr.Liang (B.S. & M.S., University of Michigan, Ann Arbor) leverages 15+ years of UL compliance experience, optimizing L20 Series for NEC Article 406 and CSA C22.2 No. 182.3.
- Bilingual Engineering Team: Delivers real-time UL documentation support (English/Chinese), accelerating approvals for US DOT and EU ENEC projects.
2. European & American Triumphs
- Landmark Deployments: Powers Munich Airport’s runway lighting and New York’s Hudson Yards, with UL2238-certified flame resistance (94V-0, Clause 4.2) ensuring public safety.
- Supply Chain Agility: 48-hour prototyping for Philips/Osmram-compatible spectral horticultural lighting systems.
