From the Unitree robots performing yangko dance on the Spring Festival Gala stage, to Boston Dynamics’ Atlas executing backflips, humanoid robots are rapidly moving from science fiction to reality. Such high-degree-of-freedom devices rely on the coordinated movement of dozens of joints, processing thousands of motion commands per second. As the core carrier for power and signal transmission, connectors directly determine the motion accuracy and operational stability of the robots.
Therefore, choosing the right manufacturer and brand is especially critical when selecting specialized connectors. Founded in 2002, Changzhou Amass Electronics Co., Ltd. (the original creator of the XT Series) has 24 years of expertise in low-voltage, high-current DC connectors for intelligent equipment below automotive grade.We are a “Little Giant” specialized & sophisticated enterprise and a national high-tech enterprise integrating design, R&D, manufacturing and sales. We hold more than 200 patents, with over 10,000 project cases and a cumulative installed base exceeding 100 million units for our customers.
Located in Lijia Industrial Park, Wujin District, Jiangsu Province, our company covers a production area of over 30,000 square meters with independent land property rights. We have a team of nearly 300 professionals dedicated to R&D, manufacturing and sales. Our more than 100 connector products serve a wide range of applications, including garden tools, energy storage equipment, electric vehicles, smart home appliances, intelligent robots, aircraft models and drones. We also provide efficient product development and production services, offering customers 7A full-cycle solutions.
The LIFTF Series connectors developed by Amass feature miniaturization, high vibration resistance and integration.They precisely address the pain points of humanoid robot applications and serve as the neural hub for their flexible operation.
The operating environment of humanoid robots places extreme demands on connectors:20–30 flexible joints must withstand repeated bending and torsion daily, high-frequency vibrations from bipedal locomotion tend to cause loose connections, and the compact humanoid structure requires the connector’s outer diameter to be below 3 mm, while simultaneously supporting simultaneous power and signal transmission. Traditional connectors often suffer from signal interruption due to excessive size and insufficient vibration resistance, becoming a bottleneck restricting the performance upgrade of robots. The LIFTF Series is fully innovated in structural design, material selection and manufacturing processes, perfectly adapting to the requirements of full-scenario operation.
The miniature integrated design overcomes the challenges of limited space. Compared with traditional connectors with a 5 mm outer diameter, the LIFTF Series reduces the size to within 3 mm, achieving dual power and signal transmission in a fingernail-sized form factor. It can be perfectly embedded into narrow cavities such as robot joints and dexterous hands. Featuring a modular integration solution, it integrates multiple signal channels in a confined space, avoiding space waste caused by separate designs, and reserving sufficient room for the layout of sensors and controllers. This adapts to the design trend of lightweight and compact humanoid robots.
Enhanced anti-vibration and anti-disconnection capabilities ensure stable dynamic transmission.Equipped with an upgraded self-locking buckle structure, it locks automatically after mating and withstands wide‑frequency vibrations.With a low contact resistance design, the contact resistance fluctuation is controlled within 3 mΩ, ensuring precise transmission of joint torque feedback signals with an error rate below 1%, providing reliable data support for the posture adjustment of humanoid robots.
Adaptable to all working conditions, the LIFTF Series builds a strong defense for durability.The housing is made of flame‑retardant PBT engineering plastic with special plating technology, featuring an operating temperature range of -40℃ to 120℃, suitable for diverse indoor and outdoor climatic regions. It remains non‑brittle at low temperatures and non‑aging at high temperatures. The dual‑sealing structure achieves IP67 protection, effectively blocking dust and oil intrusion, greatly reducing robot operation and maintenance costs, and adapting to diverse scenarios such as household service and industrial inspection. Compliant with international standards including RoHS2.0 and REACH, the series has been mass‑produced for consumer and industrial humanoid robots and exported to more than 60 countries worldwide.
Every precise movement of a humanoid robot relies on the reliable support of micro-components. The LIFTF Series connectors break performance boundaries through technological innovation, injecting core power into the stable operation of humanoid robots. Amid the wave of embodied intelligence, this "micro hub" is helping humanoid robots cross technical bottlenecks, accelerate their entry into thousands of households and industrial sites, and usher in a new era of intelligent interaction.
