Description

The FSR 402 from Interlink Electronics is a compact and reliable force sensing resistor designed for precise touch control and pressure measurement. With its polymer thick film (PTF) technology, the FSR 402 provides accurate force readings by decreasing resistance as pressure is applied. Its small 18.28 mm diameter and thin profile (0.45 mm) make it ideal for applications in diverse industries such as automotive, medical devices, consumer electronics, and industrial systems. It offers a robust, repeatable, and cost-effective solution for integrating force sensing into electronic devices.
