| TDK expands its tunnel-magnetoresistance (TMR) angle sensor portfolio with the launch of the TAS4240 TMR-based angle-sensor for automotive and industrial applications. The TAS4240 comes in a compact TSSOP8 package and provides two redundant analog single-ended SIN/COS outputs. The sensor enables precise angle measurements in applications where high performance is needed and space is limited. Samples of the TAS4240 are available now and production started in April 2022.

| What are TMR sensors? |
The TMR sensors of TDK are a new type of magnetic sensors utilizing a TMR element, which is a highly-sensitive reproducing element of an HDD head.
Compared to sensors using a hall element, TDK TMR sensors feature extremely high sensitivity and high output, and realize superior sensing capability as wheel velocity sensors for ABS (anti-lock braking) systems. Moreover, they can also be expected to be utilized as current sensors that conserve energy by controlling charging and discharging of batteries. |
