Infineon´s 3D magnetic sensor family TLE493D offers 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:
- 3 dimensional movement within a magnetic field
- Linear slide movement
- 360° angle rotation
By combining 3-axis measurement in a small package, with low power consumption, the TLE493D 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.
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.
