RP-L-170 Thin Film Pressure Sensor

The RP-L-170 is a long, flexible thin-film pressure sensor with a 170mm active area for detecting both static and dynamic pressure. As pressure is applied, the sensor's resistance decreases — making it easy to read with any analogue input on a microcontroller.

Built from ultra-thin film with nanometre pressure-sensitive layers, the sensor is just 0.35mm thick. It triggers at under 20g and measures up to 10kg or more, with a response time under 10ms and a lifespan exceeding 1 million cycles.

Key Features
