RP-S40-ST Thin-Film Pressure Sensor (FSR) 40x40mm

The RP-S40-ST thin-film pressure sensor is a versatile sensor with a square sensing area of 40 x 40 mm. This flexible sensor is ideal for precise detection and measurement of pressure in various applications. With its ability to convert pressure into electrical signals, it is optimized for both static and dynamic pressure measurements. The sensor responds to a low trigger force of 20 grams, making it extremely sensitive. At the same time, it can measure forces up to 10 kilograms, providing stable and reliable results. Thanks to its nanometer-thin pressure-sensitive layers and the use of high-quality conductive materials, it boasts a long lifespan of over one million cycles. Its fast response time of under 10 milliseconds makes it perfect for real-time applications. With an operating temperature range of -40 to +85 degrees Celsius, it functions reliably even under demanding conditions. Whether in medical applications, robotics, or smart devices, this sensor impresses with precision and versatility.

Features: 

• The sensor has a square area measuring 40 x 40 mm, which is compact and easy to integrate.  
• The pressure-sensitive layer consists of nanometer-thin materials that enable high sensitivity.  
• The resistance decreases proportionally to the pressure force, supporting accurate measurements.  
• The trigger force is only 20 grams, allowing even slight pressure changes to be detected.  
• The measurement range is from 20 grams to 10 kilograms.  
• The sensor has a long lifespan of over one million measurement cycles.  
• The operating temperature ranges from -40 to +85 degrees Celsius, allowing use in extreme environments.  
• The response time is less than 10 milliseconds, capturing rapid pressure changes.  
• It is suitable for static and dynamic pressure measurements at a frequency of up to 10 Hz.
