Generic RP-L-400 Force Sensitive Resistor (20g-10kg) - Thin Film Pressure Sensor
The RP-L-400 is a thin-film force-sensitive resistor (FSR) providing variable resistance output from 500kΩ to 500Ω over a 20g to 10kg sensing range. Its ultra-thin 0.45mm profile and flexible construction make it ideal for integration into embedded systems, robotics, and interactive electronics projects with Arduino, Raspberry Pi, or other microcontroller platforms.
Features
- Wide Force Sensing Range: Accurately measures applied force from 20 grams up to 10 kilograms.
- Variable Resistance Output: Provides an analog resistance signal ranging from approximately 500kΩ (light touch) down to 500Ω (full force).
- Ultra-Thin & Flexible Profile: With a thickness of only 0.45mm, it is suitable for space-constrained and conformal applications.
- Broad Operating Temperature: Functions reliably across an industrial temperature range from -40°C to +85°C.
- Simple Interface: Easy to integrate with voltage divider circuits for analog voltage reading by microcontrollers.

The RP-L-400 Force Sensitive Resistor operates on the principle of piezoresistivity, where the electrical resistance of its active area decreases predictably as force is applied. This change in resistance can be converted into a measurable analog voltage signal using a simple series resistor, enabling precise force detection and measurement.
Constructed with a durable, flexible polymer thick film (PTF) substrate, the sensor is designed for repeated use and can conform to curved surfaces. Its wide operating temperature range ensures stable performance in diverse environments, from industrial controls to consumer electronics, providing a reliable and cost-effective solution for tactile sensing and pressure mapping.
