RP-C7.6-ST Thin Film Pressure Sensor

The RP-C7.6-ST is a circular flexible thin-film pressure sensor with a compact 7.6 mm active area and ultra-thin 0.3 mm profile. It converts applied force into a variable resistance — output resistance decreases as pressure increases — making it straightforward to read with any microcontroller's analogue input.

With a trigger force of just 30 g and a measurement range up to 1.5 kg, this sensor responds in under 10 ms and is rated for over one million actuations. The wide −40 °C to +85 °C operating range suits both indoor and outdoor applications.
