FSR X 400 Series

The New Standard in Force Sensing

Interlink Electronics' signature line of Force Sensing Resistors^® are now available with even greater sensing ranges, giving engineers and product designers access to more potential applications than ever before. The FSR X 400 line of force sensors can detect and measure pressure from 0.3 N to 50 N while operating solo or as part of an array. A dependable workhorse, the robust sensor can withstand millions of actuations as well as harsh, dirty environments and extreme temperatures, making it a great option for applications in industries like robotics, medicine, automotive, and the IoT. 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.
