The device stands out with its ability to withstand \u003cb\u003etemperatures up to 120°C\u003c\/b\u003e and its support for direct soldering, ensuring permanent, secure connections where traditional connectors fail. Featuring a \u003cb\u003elinear sensing range of 20g to 6kg\u003c\/b\u003e, a response time under 1ms, and a lifespan exceeding 10 million cycles, it offers the reliability required for advanced robotic tactile sensing, industrial automation, and automotive electronics.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHigh-Temperature Stability up to 120°C\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eUnlike conventional pressure sensors that degrade under thermal stress, the graphene-based unit maintains stable operation in temperatures ranging from \u003cb\u003e-40°C to +120°C\u003c\/b\u003e. This thermal resilience makes the high-temperature pressure sensor particularly suitable for automotive engine bays, industrial machinery monitoring, and other environments where standard FPC sensors typically fail. The material composition ensures consistent data acquisition even during prolonged exposure to elevated heat.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePrecision Linear Output and Rapid Response\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe thin-film force sensor offers a wide detection range, accurately perceiving pressures as light as \u003cb\u003e20g and as heavy as 6kg\u003c\/b\u003e. Crucially, the resistance changes linearly with applied pressure, which significantly reduces the complexity of the algorithms required for data interpretation. Coupled with an activation time of less than 0.01 seconds and a response latency under 1ms, the tactile component allows for real-time feedback systems, essential for high-speed precision control in robotics and interactive interfaces.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eExceptional Mechanical Durability\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eReliability remains a core feature of the design, with the flexible sensor tested to withstand over 10 million mechanical presses (at 1kg force). This longevity ensures that the force-sensitive resistor functions reliably in high-frequency use cases, such as industrial counting systems, anti-touch switches, and pressure-sensitive buttons. The robust construction minimizes maintenance requirements and extends the operational life of the host equipment.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eUltra-Thin Integration with Direct Soldering\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eMeasuring only 0.45mm in thickness, the flexible module integrates seamlessly into compact spaces without altering the mechanical profile of the device. A distinct advantage of this specific model is the support for direct soldering. While many membrane sensors require specific connectors that can loosen over time, this high-temp sensor allows for permanent, secure wire connections, ensuring signal integrity in vibrating or mobile applications like wearable electronics or moving robot limbs.\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/dfimg.dfrobot.com\/enshop\/image\/data\/SEN0684\/1.jpg\" alt=\"Dimension Diagram of Circular Flex Force Sensor\" title=\"Dimension Diagram of Circular Flex Force Sensor\"\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eDimension Diagram\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/dfimg.dfrobot.com\/enshop\/image\/data\/SEN0684\/2.jpg\" alt=\"Pressure-Resistance Curve of Circular Flex Force Sensor\" title=\"Pressure-Resistance Curve of Circular Flex Force Sensor\"\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003ePressure-Resistance Curve\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/dfimg.dfrobot.com\/enshop\/image\/data\/SEN0684\/3.jpg\" alt=\"Typical Application Circuit (Series 2KΩ Resistor for Voltage Division Sampling)\" title=\"Typical Application Circuit (Series 2KΩ Resistor for Voltage Division Sampling)\"\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eTypical Application Circuit (Series 2KΩ Resistor for Voltage Division Sampling)\u003c\/p\u003e\n\u003ch2\u003eApplications:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRobotics: Gripper force feedback, tactile skin for humanoid robots.\u003c\/li\u003e\n\u003cli\u003eAutomotive: Seat occupancy detection, heated surface pressure monitoring.\u003c\/li\u003e\n\u003cli\u003eIndustrial: Safety switches in high-temp machinery, fluid level monitoring (pressure based).\u003c\/li\u003e\n\u003cli\u003eInteractive Interfaces: Pressure-sensitive touch panels, electronic musical instruments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecification:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eThickness: 0.45 mm\u003c\/li\u003e\n\u003cli\u003eActuation Force: 20g\u003c\/li\u003e\n\u003cli\u003ePressure Range: 20g ~ 6 kg\u003c\/li\u003e\n\u003cli\u003eResistance at Actuation (20g): 200 kΩ\u003c\/li\u003e\n\u003cli\u003eResistance at Full Scale (6kg): 1 kΩ\u003c\/li\u003e\n\u003cli\u003eResponse Time: 1 ms\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -40 °C ~ +120 °C\u003c\/li\u003e\n\u003cli\u003eDurability: \u0026gt; 10 million cycles (1 Kg force, flexible press)\u003c\/li\u003e\n\u003cli\u003eActivation Time: 0.01 S\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":42343283654738,"sku":"DF-SEN0684","price":11.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0735\/0383\/files\/SEN0684_Main_01.jpg?v=1774161907","url":"https:\/\/www.pakronics.co.nz\/products\/ultra-thin-circular-flex-force-sensor-0-45mm-20g-6kg-range-120c-high-temp-resistance-df-sen0684","provider":"Pakronics®","version":"1.0","type":"link"}
