3D Magnetic Sensor – Sensing the world in all three dimensions

Infineon extended its 3D magnetic sensor product portfolio with automotive and industrial derivatives. The sensor family now comprises TLE/TLI/TLV...., offering accurate three dimensional sensing with extremely low-power consumption. Within its small 6-pin package the sensor provides direct measurement of the x-, y-, and z components of a magnetic field.

Thus the sensor family is ideally suited for the measurement of:

  • detection of three dimensional movement
  • linear position measurement
  • 360° angle measurement


By combining 3-axis measurement in a small package, with low power consumption, the TLE / TLI / TLV493D sensors provide a contactless position sensing alternative to applications which traditionally use mechanical or optical solutions. The system size for these applications can be reduced as magnetic threshold stability over temperature provides a highly accurate and more robust solution for those systems.

The new 3D magnetic sensor family is a real alternative for applications which traditionally use mechanical and optical solutions, since they are robust against environmental harms like dirt or wearing, due to contactless position sensing. Furthermore reduction of development time for basic platforms is possible and moreover they can be used in different products by adjusting the software algorithm of the system.

Infineon's sensor provides a standard 2-wire digital I2C communication interface, which enables a bi-directional communication between the sensor and microcontroller. In keeping with the highest quality standards and environmental regulations, the sensor is RoHs compliant, JESD47 or AEC-Q100 qualified and supports system according functional safety standard ISO 26262.
