Force Sensitive Resistor RP-S40-ST (10g-20kg)
The RP-S40-ST is a thin-film force sensitive resistor (FSR) with a wide measurement range from 10 grams to 20 kilograms, offering a variable resistance output from 500kĪ© to 500Ī©. Its ultra-thin 0.45mm profile makes it ideal for integration into compact designs, robotics, and pressure-sensitive control systems compatible with 3.3V/5V microcontroller ADCs.
Features
- Wide dynamic force sensing range from 10g to 20kg.
- Ultra-thin, flexible form factor with a thickness of only 0.45mm.
- Variable resistance output from ~500kĪ© (no load) down to ~500Ī© (full load).
- Robust operating temperature range from -40Ā°C to +85Ā°C.
- Simple two-terminal interface for easy integration with voltage divider circuits.

The RP-S40-ST Force Sensitive Resistor operates on the principle of piezoresistivity, where the electrical resistance through a specialized polymer Matrix decreases predictably with applied force. This analog output provides a continuous variable signal proportional to pressure, enabling nuanced force measurement rather than simple on/off detection.
Designed for durability across a broad temperature spectrum, this sensor is suitable for embedded applications requiring reliable force feedback. Its thin, flexible construction allows for mounting on curved surfaces or within tight spaces, making it a versatile component for tactile interfaces, load distribution monitoring, and human-machine interaction projects.
