Material Advantages

High-quality stainless steel 17-4PH

Button load cell are typically made of high-quality stainless steel material, which provides excellent durability and corrosion resistance. They can effectively withstand harsh environments and maintain stable operation over a long period of time. Stainless steel is resistant to oxidation, corrosion, and wear, making it suitable for various applications, including outdoor, humid, and chemically corrosive environments.

Customer Case

GML669 button force sensor for robot


Our customer, a leading robotics company, was developing a robotic arm for industrial applications. The robotic arm required precise weight sensing capabilities to ensure accurate handling and manipulation of objects. They approached us to develop a miniature button load cell that could be integrated into the robotic arm.

Problems faced by customers include

The load cell needed to be compact and lightweight to fit within the limited space available in the robotic arm without compromising its functionality.The load cell had to provide highly accurate weight measurements to enable the robotic arm to handle objects of varying weights with precision.The load cell had to withstand the rigors of industrial environments, including vibrations and impacts, to ensure long-term reliability.


We developed a miniature button weighing sensor that was small in size and lightweight, allowing it to fit seamlessly into the robotic arm without adding significant bulk. The sensor utilized advanced strain gauge technology to provide precise weight measurements, ensuring the robotic arm could handle objects with utmost accuracy.We designed the sensor with durable materials and incorporated shock-absorbing features to enhance its resistance to vibrations and impacts, making it suitable for industrial environments.
