Description

The RP-L-110 Force Sensitive Resistor (FSR) operates on the principle of piezoresistivity, where applied force compresses a specialized nano-Particle sensing layer, shunting conductive traces on a flexible substrate to produce a variable resistance. This two-terminal device functions as a force-controlled variable resistor or a programmable threshold switch, requiring simple voltage divider circuits for signal conditioning with 3.3V or 5V logic systems.

Constructed from durable polyester films with a spacer adhesive layer, the sensor’s active area remains free of adhesive to ensure unimpeded force transduction. The thin, flexible form factor allows for integration into tight spaces and curved surfaces, suitable for both static load monitoring and dynamic impact sensing across a wide operational temperature range.

Frequently Asked Questions

What is the operating principle of the RP-L-110 Force Sensitive Resistor?

The RP-L-110 operates as a piezoresistive sensor. When force is applied to its active area, a nano-Particle sensing layer compresses, creating electrical shunts between conductive traces on a flexible substrate. This action decreases the electrical resistance between its two terminals proportionally to the applied force, providing an analog output signal.

How do I interface the RP-L-110 FSR with an Arduino or Raspberry Pi?

Interface the FSR using a simple voltage divider circuit. Connect one FSR terminal to your microcontroller's analog input pin (e.g., A0 on Arduino) via a fixed-value resistor (typically 10kΩ). Connect the other FSR terminal to ground. The junction between the FSR and the fixed resistor provides a variable voltage that the ADC can read, which you can then map to a force value.

What is the difference between the 20g-10kg and 50g-5kg specifications?

The 20g-10kg range indicates the sensor's full physical capability, from a minimal detectable force to its maximum limit before potential damage. The 50g-5kg range represents the recommended operational zone where the sensor provides its most linear and reliable resistance-force relationship, ensuring optimal accuracy and longevity for typical applications.
