About

Our XENSIV™ linear magnetic sensors deliver precise position detection across automotive, industrial, and consumer applications. They sense both linear and rotary movement – e.g., in shafts, triggers, sliders, and pistons – and support absolute and incremental concepts. Absolute linear sensors report true position over the full measurement range, while incremental devices provide outputs related to motion, including direction and speed.

For automotive-grade applications, our linear Hall portfolio offers multiple output options: choose the TLE4997 for analog ratiometric output, or the TLE4998/TLE4999 for digital interfaces including PSI5, PWM, SENT, and SPC. Single- and dual-die variants are available. Built-in stress compensation is a core feature of our XENSIV™ linear Hall design, reducing drift due to mechanical and package stress. The result is more stable control and long-term performance in demanding environments.

For industrial and consumer applications, our linear TMR-based sensors provide analog output with high sensitivity, low current consumption, and low hysteresis behavior – ideal for small, low- and mid-power systems that still require accurate position feedback.

Infineon's XENSIV™ linear sensors are based on two technologies – Hall effect and TMR (tunneling magnetoresistance) – enabling customization options for sensitivity, noise, bandwidth, and power.

Linear Hall sensors convert magnetic flux density into a voltage. They are robust and maintain stability over a wide temperature range. Our Hall-based devices also feature programmable signal conditioning, such as clamping, low-pass filtering, and gain adjustment, allowing for flexible integration and calibration.

Linear TMR sensors use TMR elements whose resistance changes in response to the applied magnetic field. These sensors deliver very high sensitivity, low noise, and excellent linearity even at low magnetic field strengths.

When paired with suitable magnets, XENSIV™ linear sensors provide accurate angular and linear position measurement, whether used in slider, trigger, motor control, or rotating shaft applications. They can also be employed in core-based current measurement applications, where a linear Hall sensor placed in the air gap of a ferromagnetic core measures current indirectly.

XENSIV™ TLE499x series of highly accurate linear Hall sensors are well suited for torque sensing in steering torque sensors.
Another common use case is to measure the position of throttle and pedal controls, subsequently providing data to the ECU to determine the appropriate quantity of fuel to inject.

Further applications include use in automatic transmission systems, such as gear shift detection, clutch pedal position sensing, and brake sensing. In automotive suspension systems, magnetic linear sensors are used to measure the travel of shock absorbers, enabling damping adjustment for automated headlight control.

Linear sensors are used across a broad range of position and motion-sensing applications for both industrial and consumer markets.

In industrial automation, linear sensors provide reliable position feedback for factory-automated machines, robots, conveyors, valves, and actuators. They help increase uptime and repeatability by delivering robust, low-drift signals in varied environmental conditions.

In consumer and prosumer products, these sensors enable smooth, precise control for human-machine interfaces, such as in joysticks and PC accessories; consistent operation in home appliances; stabilized motion in camera and drone gimbals; and responsive trigger and torque control in power tools.

Our XENSIV™ linear sensors combine low noise, low drift, excellent linearity, and high bandwidth across wide temperature ranges. The linear sensor portfolio includes options with integrated diagnostics, dual-die configurations, and ASIL-ready features to support functional safety concepts. We also provide application notes, magnet design guides, and evaluation kits to accelerate first-time-right designs in automotive, industrial, and consumer applications.
