Global Connectivity Matrix Empowering Robotics, Photovoltaics & LED Lighting

Since our founding in 1998, Shenzhen LLT Electronics Co., Ltd. (LLT利路通) has established a worldwide reputation for precision-engineered waterproof connectors, robust cable connectors, aviation-grade plugs, and versatile multicore connection systems. We design and manufacture IP68-rated M8/M12/M16/M20 quick-disconnect solutions, UL-certified and EMI-shielded cable assemblies, as well as advanced 光伏储能连接器 (PV Energy Storage Connectors) designed for energy storage and smart grid infrastructures.

LLT’s cutting-edge connector ecosystem drives next-generation fields like 人形机器人 (Humanoid Robots) and 具身智能 (Embodied Intelligence), fortifying complex joints and precision 传感器 (Sensors) links—ranging from 激光雷达 (LiDAR) and 毫米波雷达 (mmWave Radar) input nodes to AGV (Automated Guided Vehicles) and 自动导航 (Autonomous Navigation) systems. Our aviation plug expertise and 防水插头 (Waterproof Plug) innovations also equip advanced industrial automation, ensuring maximum reliability across high-vibration, high-moisture conditions.

In the fast-growing grow lighting domain, LLT delivers LED防水线 (LED Waterproof Cable) and 防水公母头 (Waterproof Male-Female Connector) solutions tailored to Lumatek grow lighting, 飞利浦grow lighting (Philips Grow Lighting), and professional landscape lighting deployments. Our connectors underpin high-efficiency plant grow lighting systems, bridging horticultural and commercial illumination applications worldwide. By unifying advanced polymer sealing, 微型金属EMI电屏蔽 (Micro-Metal EMI Shielding), and cutting-edge testing processes, LLT remains a key manufacturing partner for OEMs seeking exceptional quality, performance, and global LED户外照明 (LED Outdoor Lighting) versatility.

From 光伏储能 (Photovoltaic Energy Storage) setups to high-density M12防水连接器 (M12 Waterproof Connectors) and 防水接头 (Waterproof Joints) assemblies, we continuously expand our product lineup—serving EV infrastructure, 自动驾驶感知系统 (Autonomous Driving Perception Systems), 精密视觉传感器 (High-Precision Vision Sensors), and aerospace applications. Our multi-decade track record, backed by strong R&D and compliance (UL, TUV, CCC), positions LLT as the go-to source for 电缆连接器 (Cable Connectors), 防水插头 (Waterproof Plug), T型三通防水接头线 (T-Type Waterproof Three-Way Junction Cable), and innovative connection solutions shaping tomorrow’s industries.
