Ultra-thin Circular Flexible Potentiometer (0.45mm Graphene)

The Circular Flexible Potentiometer is an advanced position tracking component designed to overcome the physical limitations of traditional mechanical switches. Utilizing innovative graphene-based pressure-sensitive materials within a 0.45mm ultra-thin structure, this membrane rotary sensor converts physical pressure into a linear voltage signal ranging from 0.2V to 0.8V. Unlike bulky mechanical counterparts, this resistive film device offers a contact-based sensing mechanism with a rapid response time of less than 1 millisecond and a low trigger force of 20g. Designed for reliability, the component boasts a lifespan exceeding 1 million cycles, making it an essential solution for precise angular displacement feedback in space-constrained environments such as industrial automation systems, service robots, and smart home interfaces.

Advanced Graphene Construction for Extended Durability

At the core of this thin-film position sensor lies a composite of environmentally friendly polyester film and high-conductivity graphene. This material choice resolves common issues associated with mechanical wear and contact oxidation found in standard carbon film potentiometers. By eliminating moving mechanical parts, the flexible electronic component ensures signal stability and consistent performance over long-term use, maintaining a contact resistance below 100Ω even after extensive operation.

0.45mm Ultra-Thin Profile for Seamless Integration

Measuring only 0.45mm in thickness, the soft potentiometer is engineered for applications where vertical space is critical. Its flexible form factor allows the sensing strip to conform to curved surfaces, enabling novel designs in wearable electronics and ergonomic controllers. Installation is streamlined through the inclusion of a back-adhesive tape for quick mounting and solderable metal terminals, significantly reducing assembly time compared to rigid, through-hole components.

Pressure Application Method

Accurate control is achieved through the sensor's ability to output a continuous DC voltage that corresponds linearly to the pressure point's location. With a recommended pressure range of 20g to 200g, the angular displacement detector sensitively captures minute changes in position. This linearity allows for precise interpretation of user inputs or mechanical movements, providing real-time data essential for feedback loops in precision equipment and interactive devices.
