Infineon Technologies AG showcased its latest sensors and solutions for smart home, intelligent mobility, connected industry, robotics, and health and fitness at this year's Sensor+Test.

One primary topic of the semiconductor maker was magnetic sensors. Infineon's portfolio includes sensors based on all four magnetic technologies: HALL, GMR, AMR, and TMR.

Since functional safety requirements are steadily growing in many automotive and industrial applications, Infineon attaches particular importance to magnetic sensor technologies.

At Sensor+Test, the chip maker expanded its portfolio to include the XENSIV™ TLI4999I3, which Infineon claims to be the first linear Hall sensor for automotive applications to be rated with the highest functional safety level (ASIL-D). (See image below).


Also, Infineon launched its AMR-based XENSIV TLE5109A16 angle sensor. (See image below) With an angle error of merely 0.2 degrees, it provides more accurate measurements at low magnetic fields than comparable products on the market. In its dual-die design, XENSIV TLE5109A16 is also suitable for ASIL-D systems.

More and more applications in the industrial, consumer and automotive sectors require detailed information about the current flowing from solar inverters and electric drives to smart home appliances. Each application has different requirements.

For example, the company looked at measurement range and other parameters when it presented various application examples to demonstrate the flexible uses of its new TLI4971 current sensor based on Hall technology.

A further focus of Infineon's presence at the fair was on pressure sensors.

The company showcased the XENSIV DPS368, an extremely small and precise barometric pressure sensor for wearables, home appliances, drones, therapeutic devices and other applications. (See image below). The device measures to an accuracy of ±2cm, is water-tight up to a depth of 50m. It saves up to 80% of space compared to similar sensors.

Infineon also presented the Turbo MAP sensor XENSIV KP276, which sets a new record for accuracy (± 0.77% FSS) in the company's

portfolio. It enables exceptionally fast measurement and transfer of data. Both the high accuracy and the fast measurement capabilities help optimize the air-fuel ratio in combustion engines and hence reduce emissions.
