RP-C18.3-ST Thin-Film Pressure Sensor (FSR) 18.3x27mm

The RP-C18.3-ST thin-film pressure sensor is a flexible sensor with a round sensor area of 18.3 mm in diameter. This sensor is designed to enable highly precise pressure measurements, whether for static or dynamic pressure conditions. Thanks to its robust construction and high response speed, it is particularly versatile. The sensor converts pressure into resistance values, with resistance decreasing as pressure increases. With its durable construction and a lifespan of over one million cycles, it is suitable for a wide range of applications such as monitoring systems, medical devices, or smart clothing. Its easy handling and assembly also make it ideal for beginners and professionals in the field of sensor technology. The sensor operates reliably within a wide temperature range of -40 to +85 degrees Celsius and has a response time of under 10 milliseconds. Its ability to capture both the intensity and frequency of pressure forces allows its use in demanding and innovative projects.

Features: 

• The round sensor surface has a diameter of 18.3 mm and offers a compact design.  
• The sensor uses ultra-thin pressure-sensitive materials that ensure high mechanical stability.  
• The resistance decreases proportionally to the applied pressure force, allowing accurate measurements.  
• The trigger force is 20 grams, enabling precise and sensitive activation.  
• The pressure measurement range is between 20 grams and 6 kilograms.  
• It can measure both static and dynamic pressure with a frequency of up to 10 Hz.  
• The sensor has a long lifespan of over one million cycles.  
• It operates reliably in a temperature range from -40 to +85 degrees Celsius.  
• The response time is extremely fast at less than 10 milliseconds.  

Application examples:  

• Use as a pressure switch in electronic projects.  
• Integration into medical devices for monitoring pressure changes.  
• Use in smart shoes for motion analysis.  
• Monitoring systems for beds or seating furniture.  
• Robotics applications for detecting contact forces.
