Infineon extends XENSIV™ magnetic sensing portfolio with high-performance TMR technology

Infineon Technologies expands its proven XENSIV™ magnetic sensing portfolio with a comprehensive range of Tunnel Magnetoresistance (TMR) sensors. Complementing the company's established Hall, GMR and AMR sensing solutions, the new TMR technology unlocks unique capabilities in magnetic sensing. TMR delivers exceptional sensitivity and a high signal-to-noise ratio (SNR), enabling accurate parameter retrieval and reliable sensing from smaller magnets without bandwidth limitations. Performance is maintained across larger airgaps and with increased mechanical tolerances. This makes TMR sensors ideal for low power position sensing in gaming and HMI (Human-Machine Interface), health and lifestyle wearables, and for position and current sensing in automotive and industrial applications.

TMR technology directly addresses the industry trend toward smaller, highly adaptable systems and fast control and protection loops. Developers can achieve optimal performance within strict cost frames. For current sensing, the portfolio offers inherently insulated, in plane sensing with wide range measurement capabilities. This enables exceptionally low noise measurements with higher bandwidths and minimal signal delay times. TMR position sensors combine high sensitivity and low noise for fine motion resolution with low power consumption and robust, contactless operation that remains stable over temperature (more info).
