Ultra-thin Circular Flexible Potentiometer (0.45mm Graphene)

Description:

The Ultra-Thin Circular Flexible Potentiometer is a next-generation position sensor engineered for modern electronics requiring compact, reliable angular displacement detection. Built with graphene-enhanced pressure-sensitive film technology, this 0.45mm flexible membrane sensor delivers precise voltage output (0.2V–0.8V) in response to applied pressure, eliminating the wear and oxidation issues common in traditional mechanical potentiometers. Ideal for space-constrained applications, this soft rotaryDF_SEN sensor features sub-millisecond response time, low actuation force (20g), and exceptional durability rated for over 1 million cycles. The flexible form factor enables seamless integration into curved surfaces, wearable devices, and ergonomic interfaces, while back-adhesive mounting and solderable terminals simplify assembly. Perfect for robotics joint feedback, HMI controls, gaming triggers, IoT position monitoring, and wearable gesture detection. Operating across -20°C to +65°C with contact resistance below 100Ω, this graphene potentiometer combines advanced materials science with practical engineering for applications demanding precision, longevity, and minimal profile depth.

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.
