## Description

The RP-C18.3-LT is a circular flexible thin-film pressure sensor, 18.3mm in diameter, designed for highly sensitive detection of both static and dynamic force. When pressure is applied to the active area, resistance decreases proportionally — making it straightforward to interface with a microcontroller's ADC for pressure or force measurement. Ultra-thin at 0.4mm, it's flexible enough for embedding in wearables, medical devices, footwear, and bed monitoring systems, while remaining durable for over one million actuation cycles. Specifications Active Area Diameter – 18.3mm Thickness – 0.4mm Pressure Range – 20g to 6kg Trigger Force – 20g (initial resistance drops below 200kΩ) Initial Resistance – >10MΩ (unloaded) Activation Time – <10ms Response Time – <10ms Dynamic Pressure – Up to 10Hz frequency Drift – <5% at 2.5kg static load over 24h Hysteresis – ±10% at 1000g Operating Temperature – −40°C to +85°C Lifespan – >1 million actuations EMI/ESD – None generated Ideal For Pressure switches and touch detection Smart footwear and wearable force sensing Bed and chair occupancy monitoring systems Medical device pressure measurement Robotics gripper feedback and tactile sensing Package Contents 1× RP-C18.3-LT Thin Film Pressure Sensor Resources Product Wiki & Documentation
