About

Magnetic speed sensors with TMR, GMR, and Hall effect technology

Achieve precision in every rotation with our specialized magnetic speed sensor portfolio.

Infineon's XENSIV™ magnetic speed sensors harness the power of TMR, GMR, and Hall effect technologies to deliver accurate linear and rotational speed measurements. Our latest innovations feature high-sensitivity TMR technology, combining the benefits of GMR and Hall effect for exceptional sensitivity across a broad operating range.

How it works:

  • TMR-based speed sensors: Offer the best of GMR and Hall technologies, combining high sensitivity with a wide operating range.
  • GMR-based speed sensors: Measure changes in resistance caused by magnetic field fluctuations, providing reliable speed detection.
  • Hall effect speed sensors: Utilize the Hall effect principle, where a voltage is generated when a magnetic field intersects a semiconductor with a current, enabling precise speed measurement.

Applications:

Infineon's magnetic speed sensors seamlessly integrate with ferromagnetic gear tooth wheels or magnetic encoders, allowing for precise speed and position measurement. Discover the versatility and accuracy of our magnetic speed sensors, designed to meet the demands of various applications.

Ideal all-purpose magnetic speed sensors for wheel speed sensing

Active wheel-speed sensors are an integral part of brake control systems. They detect the rotational wheel speed of vehicles using a non-contacting measurement principle.

Wheel speed sensors are installed on each wheel of the car, independent of the drive system. The speed information is used for several vehicle functions such as ABS, ESC, or ADAS applications. Dedicated sensors also provide direction information in addition to speed.

Infineon offers dedicated wheel speed sensors in TMR, GMR, and Hall technology:

  • TLE494x Hall effect series
  • TLE504x GMR series
  • TLE554x TMR series

XENSIV™ speed sensors for speed and direction detection

Infineon's XENSIV™ transmission speed sensors deliver precise speed and direction signals for high-performance transmissions with both magnetic encoder (pole wheel) and ferromagnetic (steel wheel) targets. They combine ultra-low jitter, active vibration suppression, robust EMC performance, and wide air-gap capability. 

The portfolio spans Hall and TMR-based sensors with 2-wire current and 3-wire voltage interfaces, offering strong stray-field immunity, adaptive hysteresis, and dynamic self-calibration—ideal for conventional and hybrid drivetrains. They are also suitable for related industrial applications.

All sensors are automotive AEC‑Q100 qualified and available in lead-free, halogen-free PG‑SSO (Shrink Small Outline) packages, including ISO 26262-compliant functional safety options.

  • TLE495x Hall effect series
  • TLE5555x TMR series
