FSRUX-400Pushing the Boundaries of Force Sensing

Interlink Electronics' signature line of Force Sensing Resistors® (FSR) are now available with even greater sensing ranges, giving engineers and product designers access to more potential applications than ever before. The FSR UX 400 line of sensors can detect and measure pressure from 0.5 N to 150 N while operating solo or as part of an array. A dependable workhorse, the robust two-wire sensor can withstand millions of actuations and operate in harsh, messy environments and under extreme temperatures, making it a great option for industrial, medical, or automotive applications. Leveraging our 35 years of experience, Interlink's in-house team can work with clients to create custom sensing solutions that incorporate the FSR UX.
