The 3D sensors track movement in all directions, use less power, work in all conditions, and help make systems safe, small, and easy to build.
Infineon Technologies has introduced the third generation of its XENSIV 3D magnetic Hall-effect sensor family, featuring three new series: TLE493D-W3B6-Bx, TLE493D-P3B6, and TLE493D-P3I8. These sensors are developed in line with ISO26262 and include integrated diagnostic functions to support functional safety.
The sensors measure magnetic fields in three orthogonal directions and are available with I²C or SPI communication. They come in multiple measurement ranges and support supply voltages of both 3.3 V and 5 V. Designed for operation in a wide temperature range, the sensors offer high magnetic performance and long-term accuracy, with minimal deviation. A built-in wake-up mode keeps power consumption low.
These technical features give system designers greater flexibility. The 3D measurement capability allows a single sensor to replace multiple traditional sensors, enabling compact and simplified designs. With high accuracy maintained over time, the sensors reduce the need for recalibration and support robust system performance in harsh conditions. The I²C/SPI interfaces make integration into existing digital systems straightforward, and compatibility with common supply voltages simplifies power management.
For developers working on safety-critical automotive systems, ISO26262 compliance and built-in diagnostics make it easier to meet ASIL-B requirements without adding extra safety layers. The wide temperature range ensures consistent performance in both engine compartments and interior controls. The multiple magnetic range options mean the same sensor family can be used across various applications—from linear position sensing in valves and pedals to angular sensing in infotainment knobs or steering wheel controls.
In real-world use, this means fewer components to manage, faster development cycles, and more reliable system performance. Whether in automotive, industrial, or consumer products, these sensors help reduce design complexity while improving safety and efficiency. With low power operation and long-term stability, they’re also well-suited for energy-conscious and maintenance-sensitive applications.
