The FT-4x00 series MEMS Force sensor represents the highest performance, smallest size and most reliable force sensing solution in the market. Designed to serve a broad range of applications such as buttons, sliders and screens, the FT-4x00 series can be used with or without capacitive touch controllers to enable a robust 3D touch experience.The FT-4x00 series sensing solutions enable new gapless industrial designs, provide 10x higher reliability compared to mechanical switches and can be used with any material including metal, glass, plastic, ceramic, wood, leather, etc.The FT-4x00 series sensors along with proprietary algorithms accurately measure force associated with a touch event on any surface. This MEMS-based solution performs precisely and consistently over temperature and humidity changes and is immune to radio frequencies (RF) and electro-magnetic interference (EMI).The FT-4x00 is the world’s smallest WLCSP MEMS Force sensor and it uses standard pick-and-place assembly and reflow soldering onto PCB/FPCB substrates.
