Standard magnetic tactile sensor module - MLX90901
Product description
New technology. Engineering samples available in limited quantities
The MLX90901 is a fully calibrated tactile sensor module that delivers precise 3D force feedback for advanced robotic systems. It accurately measures applied forces and translates them into a digital 3D vector at up to 400Hz, along with their localization heatmap on the module sensing surface.
Built on Melexis’ magnetic Tactaxis® technology, it combines the sensor, magnet, elastomer, mechanical structure, and supporting electronics within a single complete unit. It resolves the contact force across three axes, capturing normal force together with shear in two directions.
Built for reliability, the MLX90901 boasts exceptional thermal stability through temperature monitoring and magnetic offset compensation, along with robust immunity to external stray magnetic fields. Unlock enhanced dexterity and interaction for your robots with the MLX90901 and comprehensive supporting software libraries.
The DVK90901 evaluation kit provides developers a straightforward route to benchmark the MLX90901, characterize its three-axis force response, and begin integrating the module into robotic hand designs. Support for I²C simplifies connection to robotic hand controllers.
