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.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAdvanced Graphene Construction for Extended Durability\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eAt 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.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e0.45mm Ultra-Thin Profile for Seamless Integration\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eMeasuring 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.\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/dfimg.dfrobot.com\/enshop\/20251216\/1%20(2).jpg\" alt=\"Dimension Diagram of\" title=\"Dimension Diagram of\"\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cb\u003eDimension Diagram\u003c\/b\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cb\u003e\u003cbr\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e \u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cb\u003e\u003cimg src=\"https:\/\/dfimg.dfrobot.com\/enshop\/20251216\/2.jpg\" alt=\"Pressure Application Method of\" title=\"Pressure Application Method of\"\u003e\u003cbr\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cb\u003e\u003cb\u003ePressure Application Method\u003c\/b\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eAccurate 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.\u003c\/p\u003e\n\u003ch2\u003eApplications:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRobotics: Joint angle detection and soft-touch feedback.\u003c\/li\u003e\n\u003cli\u003eHMI Interfaces: Custom volume knobs, lighting dimmers, or scroll wheels on curved surfaces.\u003c\/li\u003e\n\u003cli\u003eGaming: Creating ultra-low profile triggers or circular input pads.\u003c\/li\u003e\n\u003cli\u003eIoT Devices: Position monitoring in smart locks or valve controllers.\u003c\/li\u003e\n\u003cli\u003eWearables: Integration into clothing or accessories for gesture detection.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecification:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eThickness: 0.45mm\u003c\/li\u003e\n\u003cli\u003eActuation Force: 20g-50g\u003c\/li\u003e\n\u003cli\u003eRecommended Pressure: 20g-200g\u003c\/li\u003e\n\u003cli\u003eRecommended Plunger: Curved Spring \/ D3 Rubber Tip\u003c\/li\u003e\n\u003cli\u003ePressure Application Method: Spring Plate \/ Spring \/ Weight Block\u003c\/li\u003e\n\u003cli\u003eContact Resistance: 100Ω\u003c\/li\u003e\n\u003cli\u003eOff-State Resistance: Infinite (V1-V0, V1-V+)\u003c\/li\u003e\n\u003cli\u003eActivation Time: 0.01s\u003c\/li\u003e\n\u003cli\u003eDurability: 1 million cycles (normal flexible pressing)\u003c\/li\u003e\n\u003cli\u003eResponse Time: 1ms\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -20 ~ +65\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eProduct Includes:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCircular Flexible Potentiometer x1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":42343285325906,"sku":"DF-SEN0686","price":14.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0735\/0383\/files\/SEN0686_Main_01.jpg?v=1774161986","url":"https:\/\/www.pakronics.co.nz\/products\/ultra-thin-circular-flexible-potentiometer-0-45mm-graphene-df-sen0686","provider":"Pakronics®","version":"1.0","type":"link"}
