{"title":"Ultra-Thin Circular Flexible Potentiometer - 0.45mm Graphene","handle":"ultra-thin-circular-flexible-potentiometer-0-45mm-graphene","url":"/products/ultra-thin-circular-flexible-potentiometer-0-45mm-graphene","description":"This circular flexible potentiometer is a membrane-based position sensor for adding low-profile rotary or angular input to space-constrained electronics. Instead of using a bulky mechanical rotary switch, it detects pressure along its sensing ring and provides a linear analogue voltage signal from 0.2V to 0.8V.The sensing layer uses graphene pressure-sensitive material in an ultra-thin 0.45mm flexible structure, helping it fit into compact controllers, smart devices, wearables and robotics assemblies. Its flexible construction can conform to curved housings, making it useful where a rigid through-hole potentiometer would be difficult to mount.Installation is designed to be straightforward, with adhesive backing and solderable metal terminals for integration into prototypes or production hardware. One Circular Flexible Potentiometer is included.Features:Ultra-thin 0.45mm flexible membrane structure for compact integrationGraphene-based pressure sensing material for improved durabilityLinear analog voltage output corresponding to pressure positionLow actuation force starting at 20g for sensitive input detectionFast response time under 1ms for real-time control systemsDurability exceeding 1 million activation cyclesAdhesive backing and solderable terminals for simplified installationFlexible design compatible with curved surfaces and ergonomic interfacesSpecifications:Thickness: 0.45mmActuation Force: 20g-50gRecommended Pressure: 20g-200gRecommended Plunger: Curved Spring / D3 Rubber TipPressure Application Method: Spring Plate / Spring / Weight BlockContact Resistance: ＜100ΩOff-State Resistance: Infinite (V1-V0, V1-V+)Activation Time: ＜0.01sDurability: ＞1 million cycles (normal flexible pressing)Response Time: ＜1msOperating Temperature: -20℃ ~ +65℃Suitable applications include robotics joint feedback, custom human-machine interfaces, gaming controls, IoT position monitoring and wearable gesture input.","vendor":"DFRobot","product_type":"Position Sensor","in_stock":true,"options":[],"variants":[{"id":15969,"title":"Default Title","sku":"DF-SEN0686","mpn":"SEN0686","price":14.5,"on_sale":false,"in_stock":true,"available_quantity":175}]}
