Thin Film Force Sensitive Resistor

The FSR402 is a thin-film force-sensitive resistor offering high sensitivity within a minimal physical footprint. Measuring just 0.5 inches in diameter, it uses a plastic-and-metal composite structure to convert mechanical pressure into measurable resistance changes across a 0 g–10 kg range. Its ultra-thin profile and lightweight nature enable embedding in flexible or moving assemblies. Rated for 10 million actuations, it maintains stable performance under repeated use. Intended for functional pressure indication rather than calibrated measurement, it excels in applications demanding reliable contact detection, load thresholding, or relative force comparison—such as robot locomotion feedback, robotic hand control, or controlled bite-force trials in preclinical research.
